java.lang.Object edu.cmu.sphinx.linguist.acoustic.tiedstate.HTKLoader
public class HTKLoader
Remark1: S4 does not use HMM tying: the HTK "tiedlist" is not loaded nor user for now Remark2: HTK does nearly never backoff to monophones, whereas S4 might do it. Hence, all 1ph must be present, which is not always the case in HTK models. In this file, we have simply tied all 1phs to the first 3ph found with the same base phone. This is clearly not the best option, this may impact the performances. A better alternative should be proposed. Remark3: HTK is case-sensitive, while S4 requires upper-case names. A good option would be to modify S4 to make it case-sensitive, but in this version, I have rather built a class "NamesConversion" to transform the models, lexicons and grammar. Remark4: HTK does not have separate filler file. It should be quite easy to define the fillers in the configuration of HTKLoader, but I have not yet done it. For now, a separate filler file must be built. Remark5: The HTK/Julius lexicon has different fields for the word name and the printed output. We simply delete and don't use this field ("[...]") in this version. This modify the way scoring must be done. WARNING ! Remark6: Diphones are not allowed in S4 (?), and when they occur in the HTK MMF, the 2ph is transformed into a 3ph with "SIL" context. When both the transformed 2ph and the 3ph coexists in the MMF file, only the first one is kept (!) Remark7: HTKloader does not support yet all the HTK format. However it should work for standard 3ph models (it supports state/transition tying).

Formula 1: Albon fastest before crashing in wet Brazilian practice
SAO PAULO: Red Bull's Alexander Albon set the pace in a damp first practice for the Brazilian Grand Prix on Friday before crashing into the tyre wall and bringing the session to a premature end.
The British-born Thai rookie, confirmed earlier in the week by his team for 2020 alongside Dutch youngster Max Verstappen, lapped the Interlagos circuit with a best time of one minute 16.142 seconds on intermediate tyres.
Albon then paid the price for switching to slicks on a drying track, the Thai bringing out the red flags with two and a half minutes remaining after skidding out near the still slippery last corner.
Valtteri Bottas was second quickest for Mercedes, 0.551 slower, with team mate Lewis Hamilton one of four drivers who completed laps but without setting any times on a wet morning in Sao Paulo.
Mercedes and Hamilton have already wrapped up both championships, with Hamilton taking his sixth in Texas two weeks previously.
Mercedes said there were no problems with Hamilton's car. The weekend forecast is for dry conditions, meaning that there was little to be gained from running in the wet.
Ferrari's Sebastian Vettel and team mate Charles Leclerc were third and fourth on the timesheets.
Monegasque Leclerc, third in the championship, will have a 10-place grid penalty for Sunday's penultimate race of the season after an engine change.
Verstappen, runner-up to Hamilton in Brazil last year after leading and then tangling with backmarker Esteban Ocon who had tried to unlap himself, failed to clock a time.
The Dutchman, also trying out the slicks, spun through the Senna Esses without hitting anything just before Albon went off and reported conditions were still too slippery.
"We're looking for some form of retribution from last year," Red Bull principal Christian Horner told Sky Sports F1 television.

Concurrency and Threads
Threads vs Processes
- Traditional Operating Systems have Processes
- Each process has its own address space
- Single thread of control
- When a process makes a system call, the process blocks until the call completes.
- In many situations it is desirable to have multiple threads of control for:
Explicit parallelism - to take advantage of multiple processors
- To allow computation to continue while waiting for system calls to return
- example: one thread reads a file into a buffer, another thread compresses the buffer, and a final thread writes out a compressed file.
To reduce the cost of context switching
Implicit parallelism - to keep a single processor busy
What are Processes, Threads?
- Processes have:
- Program counter
- Stack
- Register set
- An exclusive virtual address space
- Sandboxing from other process except to the extent that the process participates in IPC
- Threads:
- Threads can be thought of (and are often referred to as) lightweight processes
- Provide multiple threads of control
- Have multiple program counters
- Have multiple stacks
- One parent process, the virtual address space is shared across processes
- Each thread runs sequentially
- In a given process with N threads, 0-i threads may be blocked, and 0-k threads are runnable or running.
Common Threading Use Cases
- Parallel computation:
- An algorithm is designed to solve some small part or subproblem of a larger problem
- To the extent that the subproblems are not inter-dependent, they can be executed in parallel
- Multiple threads can work against a common task queue.
Warning
The focus of this course is on distributed (not parallel) systems. Nevertheless, you may find that you want to take advantage of parallel computing in your work. We encourage you to read Christopher and Thiruvathukal, http://hpjpc.googlecode.com, which contains many examples of parallel algorithms in Java. You may also find LÃ¤ufer, Lewis, and Thiruvathukal’s Scala workshop tutorial helpful. See http://scalaworkshop.cs.luc.edu.
- Example Parallel Computation - factoring an integer
- Example Pipeline Processing - a more concise and language friendly file compression
- Helper class - ThreadedList
Mutual Exclusion
Mutual exclusion is a general problem that applies to both processes and threads.
- Processes
- Occurs with processes that share resources such as shared memory, files, and other resources that must be updated atomically
- When not otherwise shared, the address space of a process is protected against reads/writes by other processes
- Threads
- Because threads share more resources such as having a shared process heap, there are more resources that need to be potentially protected
- Because the address space is shared among threads in one process, cooperation and coordination is required for threads that read from and write to shared data structures
When mutual exclusion is achieved, atomic operations on shared data structures are guaranteed to be atomic and not interrupted by other threads.
Mutex Example/Java
This code example shows how to implement a classic mutex, a.k.a. a Lock, in Java.
These examples come from http://hpjpc.googlecode.com by Christopher and Thiruvathukal.
Semaphore Example
This shows how to implement a counting semaphore in the Java programming language.
Barrier
This shows how to implement a barrier, which is a synchronization mechanism for awaiting
a specified number of threads before processing can continue. Once all threads have arrived,
processing can continue.
Deadlock - a classic problem
A classic problem in computer science and one that is often studied in operating systems
to show the hazards of working with shared, synchronized state, is the dining philosophers problem.
We won’t describe the entire problem here but you can read http://en.wikipedia.org/wiki/Dining_philosophers_problem.
our “solution” has the following design:
- Fork: A class to represent the forks shared by adjacent philosophers at the table.
- Diner0: A class used to represent a philosopher. The philosopher does three things a philosopher normally does: think(), sleep(), and eat().
- Diners0: A class used to represent all of the diners seated at the table with their shared forks. This is where the concurrency takes place.
Fork
Diner0
Diners0
Diners1 - eliminating deadlock with resource enumeration
Execution - With Deadlock
If you have Java and Gradle installed on your computer, you can try these out!
Make sure you have the HPJPC source code:
hg clone https://bitbucket.org/loyolachicagocs_books/hpjpc-source-java
The following Gradle task in build.gradle shows how to run Diners0’s main() method:
To build:
To run:
If you run this, you will notice that deadlock ensues fairly quick.
We assume they have moved over to the bar or found a nice place to have dessert.
Common Data Structures in Concurrent Programming
- Bound Buffer
- Makes use of a mutex and semaphore internally
- Defines a maximum number of items that exist in the bound buffer’s queue.
- Has two operations: Enqueue() and Dequeue()
- Enqueue() - enqueues items in the data structure. If the enqueue operation would cause the bound buffer to exceed the maximum, the Enqueue() call will block until another thread dequeues at least one item.
- Dequeue() - dequeues an item from the data structure. If there are zero items in the queue, Dequeue() will block until another thread enqueues an item in the data structure
- Bound buffers are used to make sure that when one thread is producing work for a second thread, that if one thread is faster or slower than the other, that they appropriately wait to some extent for each other.
Example Bound Buffer
Design Considerations
- Threading requires the support of the operating system - a threading library / package is needed
- In Windows, this is a part of the Windows SDK and .NET Framework
- In Linux and Mac OSX, PThreads provides threading
- Thread usage and creation
-
- The total number of threads
- Having several hundred threads on a system with an order of magnitude fewer cores can cause you to run into trouble.
- If a majority of those threads are runnable, then the program will spend most of its time context switching between those threads rather than actually getting work done.
- If such a system is dynamically starting and stopping threads, then the program will most likely spend most of its time creating and destroying threads.
Kernel Threads vs User Mode Threads
- There are two types of threads:
- Kernel Threads
-Supported by modern operating systems
-Scheduled by the operating system
- User Threads
-Supported by almost everything
-Scheduled by the process
- Context switching:
- Kernel threads have a higher overhead because the scheduler must be invoked and there might be a time lag before a runnable thread is actually executed.
- Kernel threads often perform very well because the operating system has more information about the resource state of the computer and can make better global scheduling decisions than can a program
- User-mode threads can context switch with fewer overall operations, but scheduling them is guess-work.
- User mode threads can be created more rapidly because new stacks and scheduler entries do not need to be created by the operating system
- Where are user-mode threads used?
- In systems without kernel mode threads
- When the number of threads a system needs is in the hundreds or thousands (user-mode threads scale better in these scenarios)
- Where are kernel-mode threads used?
- When the number of threads is not very high (less than 10 per core)
- When blocking calls are involved (user-mode thread libraries usually have separate I/O libraries)
Concurrent File Copy Example
- FileCopy0: The sequential version
- FileCopy1: The concurrent version
Sequential File Copy
Concurrent File Copy Organization
Quick overview of the various classes:
- Pool: Maintains a list of buffers that can be used for allocating/freeing blocks of data without triggering new (or dispose) repeatedly.
- Buffer: Used as a shared object for reading and writing blocks of data (via the FileCopyReader1 and FileCopyWriter1 classes)
- BufferQueue: Used to queue up blocks as they are read or written. This allows for varying speeds of reader and writer, subject to the number of blocks available in the Pool.
- FileCopyReader1: Used to run the reader thread.
- FileCopyWriter1: Used to run the writer thread.
- FileCopy1: Used to act as a drop in replacement for FileCopy0. Sets up the reader and writer threads and then joins with both when the reading/writing are completed.
Execution
You can run FileCopy0 and FileCopy1 by using the corresponding Gradle tasks.
As shown, there are two properties you can set: fc0_src and fc0_dest:
gradle FileCopy0 -Pfc0_src=inputFile -Pfc0_dest=outputFile
You can also run FileCopy1 (the same parameter names are used):
gradle FileCopy1 -Pfc0_src=inputFile -Pfc0_dest=outputFile


In the ﬁxed boundary equilibrium problem, the shape of the boundary magnetic surface (it is also the boundary of the computational region) is given while the shape of the inner ﬂux surface is to be solved. A simple analytical expression for a D-shaped magnetic surface takes the form
|
| (427) |
|
| (428) |
with 𝜃 changing from 0 to 2π. According to the deﬁnition in Eqs. (29), (30), and (32) we can readily verify that the parameters a, R0, κ appearing in Eqs. (427) and (428) are indeed the minor radius, major radius, and ellipticity, respectively. According to the deﬁnition of triangularity Eq. (31), the triangularity δ for the magnetic surface deﬁned by Eqs. (427) and (428) is written as
|
| (429) |
Another common expression for the shape of a magnetic surface was given by Miller[8, 20], which is written as
|
| (430) |
|
| (431) |
Note that Miller’s formula is only slightly diﬀerent from the formula (427). For Miller’s formula, it is easy to prove that the triangularity δ is equal to Δ (instead of δ = sinΔ as given in Eq. (429)).
In the iterative metric method[11] for solving the ﬁxed boundary equilibrium problem, we need to provide an initial guess of the shape of the inner ﬂux surface (this initial guess is used to construct a initial generalized coordinates system). A common guess of the inner ﬂux surfaces is given by
|
| (432) |
|
| (433) |
where α is a parameter, ψ is a label parameter of ﬂux surface. If the shape of the LCFS is given by Eqs. (427) and (428), then Eqs. (432) and (433) are written as
|
| (434) |
|
| (435) |
Fig. 29 plots the shape given by Eqs. (434) and (435) for a =0.4, R0 = 1.7, κ = 1.7, Δ = arcsin(0.6), and α = 1 with ψ varying from zero to one.

Hi! I'm Sandy and welcome to my food blog. Each week I usually try a new recipe and post it here to share it with the world. If you enjoy any of the recipes that I post, please feel free to share it or leave a comment.
I grew up in Northamptonshire, UK and learned to cook from my mother. Once I had left home and became independant I started cooking full time and even managed to sell some of my baked goods at local markets. Now I work full-time within the web design and development industry but my love for cooking remains.
Although I always try to eat a healthy balanced diet myself, I know that some people have food allergies and intolerences so I try to mix things up a bit so everyone can try some of my recipes. I am certified in Nutrition and health which also includes the management of diabetes. So, trust me, I do understand.

The Axis jar files are built in the xml-axis/java/build/lib
directory. Here is an example CLASSPATH, which I use when developing
code:
If you access the internet via a proxy server, you'll need to set an environment variable so that the Axis tests do the same. Set ANT_OPTS to, for example:D:\\xerces\\xerces-1_4_2\\xerces.jar
G:\\junit3.7\\junit.jar
G:\\xml-axis\\java\\build\\lib\\commons-discovery.jar
G:\\xml-axis\\java\\build\\lib\\commons-logging.jar
G:\\xml-axis\\java\\build\\lib\\wsdl4j.jar
G:\\xml-axis\\java\\build\\lib\\axis.jar
G:\\xml-axis\\java\\build\\lib\\log4j-1.2.8.jar
G:\\xml-axis\\java\\build\\classes
-Dhttp.proxyHost=proxy.somewhere.com -Dhttp.proxyPort=80 -Dhttp.nonProxyHosts="localhost"
org.apache.axis.components.logger.LogFactory
is the factory,
or discovery mechanism, for the logger component/service.
The org.apache.axis.components.image
package demonstrates
both a factory, and supporting classes for different image tools used
by Axis. This is representative of a pluggable component that uses
external tooling, isolating it behind a 'thin' wrapper to Axis that
provides only a limited interface to meet Axis minimal requirements.
This allows future designers
and implementors to gain an explicit understanding of the Axis's
specific requirements on these tools.
To use the JCL SPI from a Java class, include the following import statements:
import org.apache.commons.logging.Log;
import org.apache.axis.components.logger.LogFactory;
log
attribute as follows:
public class CLASS
{
private static Log log = LogFactory.getLog(CLASS.class);
...
Messages are logged to a logger, such as log
by invoking a method corresponding to priority:
The Log
interface defines the following methods for use
in writing log/trace messages to the log:
log.fatal(Object message);
log.fatal(Object message, Throwable t);
log.error(Object message);
log.error(Object message, Throwable t);
log.warn(Object message);
log.warn(Object message, Throwable t);
log.info(Object message);
log.info(Object message, Throwable t);
log.debug(Object message);
log.debug(Object message, Throwable t);
log.trace(Object message);
log.trace(Object message, Throwable t);
In addition to the logging methods, the following are provided:
log.isFatalEnabled();
log.isErrorEnabled();
log.isWarnEnabled();
log.isInfoEnabled();
log.isDebugEnabled();
log.isTraceEnabled();
Configuration of the behavior of the JCL ultimately depends upon the logging toolkit being used. The JCL SPI (and hence Axis) uses Log4J by default if it is available (in the CLASSPATH).
Configure Log4J using system properties and/or a properties file:
Use this system property to specify the name of a Log4J configuration file.
If not specified, the default configuration file is log4j.properties.
A log4j.properties file is provided in axis.jar
.
This properties file can sometimes be overridden by placing a file of
the same name so as to appear before axis.jar
in the CLASSPATH.
However, the precise behaviour depends on the classloader that is in use
at the time, so we don't recommend this technique.
A safe way of overriding the properties file is to replace it in axis.jar. However, this isn't very convenient, especially if you want to tweak the properties during a debug session to filter out unwanted log entries. A more convenient alternative is to use an absolute file path to specify the properties file. This will even ignore web app's and their classloaders. So, for example on Linux, you could specify the system property:
log4j.configuration=file:/home/fred/log4j.props
LogFactory.getLog(logger.name)
,
used to create the logger instance. Priorities are:
DEBUG
,
INFO
,
WARN
,
ERROR
,
or FATAL
.
Log4J understands hierarchical names,
enabling control by package or high-level qualifiers:
log4j.logger.org.apache.axis.encoding=DEBUG
will enable debug messages for all classes in both
org.apache.axis.encoding
and
org.apache.axis.encoding.ser
.
Likewise, setting
log4j.logger.org.apache.axis=DEBUG
will enable debug message for all Axis classes,
but not for other Jakarta projects.
A combination of settings will enable you to see the log events that you are interested in and omit the others. For example, the combination:
log4j.logger.org.apache.axis=DEBUG log4j.logger.org.apache.axis.encoding=INFO log4j.logger.org.apache.axis.utils=INFO log4j.logger.org.apache.axis.message=INFOcuts down the number of a log entries produced by a single request to a manageable number.
For example: one can capture DEBUG (and higher) level information in a logfile, while limiting console output to INFO (and higher).
org.apache.axis.transport.http.AxisServlet
class
supports a number of standard query strings (?list, ?method, and ?wsdl) that
provide information from or perform operations on a web service (for instance, ?method is
used to invoke a method on a web service and ?wsdl is used to retrieve the WSDL document for
a web service). Axis servlets are not limited to these three query strings and developers may
create their own "plug-ins" by implementing the org.apache.axis.transport.http.QSHandler
interface. There is one method in this interface that must be implemented, with the following signature:
public void invoke (MessageContext msgContext) throws AxisFault;The
org.apache.axis.MessageContext
instance provides the developer with a number of useful
objects (such as the Axis engine instance, and HTTP servlet objects) that are accessible by its
getProperty
method. The following constants can be used to retrieve various objects provided
by the Axis servlet invoking the query string plug-in:
String
containing the name of the query string plug-in. For instance, if the query string ?wsdl is
provided, the name of the plugin is wsdl.
String
containing the name of the Axis servlet that inovked the query string plug-in.
Boolean
containing true
if this version of Axis is considered to be in development
mode, false
otherwise.
Boolean
containing true
if listing of the Axis server configuration is allowed,
false
otherwise.
org.apache.axis.server.AxisServer
object containing the engine for the Axis server.
javax.servlet.http.HttpServletRequest
object from the Axis servlet that invoked the
query string plug-in
javax.servlet.http.HttpServletResponse
object from the Axis servlet that invoked the
query string plug-in
java.io.PrintWriter
object from the Axis servlet that invoked the
query string plug-in
org.apache.commons.logging.Log
object from the Axis servlet that invoked the query
string plug-in, which is used to log messages.
org.apache.commons.logging.Log
object from the Axis servlet that invoked the query
string plug-in, which is used to log exceptions.
import
statements have been
omitted for brevity):
public class QSClockHandler implements QSHandler { public void invoke (MessageContext msgContext) throws AxisFault { PrintWriter out = (PrintWriter) msgContext.getProperty (HTTPConstants.PLUGIN_WRITER); HttpServletResponse response = (HttpServletResponse) msgContext.getProperty (HTTPConstants.MC_HTTP_SERVLETRESPONSE); response.setContentType ("text/html"); out.println ("
" + System.currentTimeMillis() + "
"); } }Once a query string plug-in class has been created, the Axis server must be set up to recognize the query string which invokes it. See the section Deployment (WSDD) Reference in the Axis Reference Guide for information on how the HTTP transport section of the Axis server configuration file must be set up.
System.getProperty()
,
and instead call AxisProperties.getProperty
.
AxisProperties.getProperty
will
call System.getProperty
, and will (eventually)
query other sources of configuration information.
Using this central point of access will allow the global configuration system to be redesigned to better support multiple Axis engines in a single JVM.
These guidelines are fundamentally independent of programming language. They are based on experience, but proper credit must be given to More Effective C++, by Scott Meyers, for opening the eyes of the innocent(?) many years ago.
Finally, these are guidelines. There will always be exceptions to these guidelines, in which case all that can be asked (as per these guidelines) is that they be logged in the form of comments in the code.
There are a few corrollaries to this rule.
main
method or program.
For a middleware component, this is the entry point(s) into the component.
For Axis this is AxisServlet
or equivalent.
After catching specific exceptions which can be resolved internally, the outermost code must ensure that all internally generated exceptions are caught and handled. While there is generally not much that can be done, at a minimum the code should log the exception. In addition to logging, the Axis Server wraps all such exceptions in AxisFaults and returns them to the client code.
This may seem contrary to the primary rule, but in fact we are claiming that Axis does know what to do with this type of exception: exit gracefully.
When in doubt, log the exception.
When in doubt, log the exception and any related local information that can help to identify the complete context of the exception.
Log the exception as an error (log.error()
)
if it is known to be an unresolved or unresolvable error,
otherwise log it at the informative level (log.info()
).
e
is caught and wrapped
by a new exception w
,
log exception e
before throwing w
.
Log the exception as an error (log.error()
)
if it is known to be an unresolved or unresolvable error,
otherwise log it at the informative level (log.info()
).
e
is caught and resolved,
logging of the exception is at the discretion of the coder and reviewers.
If any comments are logged, the exception should also be logged (log.info()
).
Issues that must be balanced are performance and problem resolvability.
Note that in many cases, ignoring the exception may be appropriate.
Exceptions raised in the business logic (this includes the server and Axis handlers) must be delivered to the client code.
handlers
, providers
and other
user controllable hook-points must be guarded
by catch(Exception ...)
.
Exceptions generated by user code and caught by system code should be:
cd xml-axis/javaTo run the tests:
ant compile
cd xml-axis/javaNote: these tests start a server on port 8080. If this clashes with the port used by your web application server (such as Tomcat), you'll need to change one of the ports or stop your web application server when running the tests.
ant functional-tests
Please run ant functional-tests and ant all-tests before checking in new code.
sample00=My name is {0}, and my title is {1}.
Messages.getMessage("sample00", "Rich Scheuerle",
"Software Developer");
if ( operationName == null )
throw new AxisFault( "No operation name specified" );
We will add an entry into org/apache/axis/i18n/resource.properties:
noOperation=No operation name specified.
And change the code to read:
if ( operationName == null )
throw new AxisFault(Messages.getMessage("noOperation"));
java.util.ResourceBundle
to access property files and message strings,
and uses java.text.MessageFormat
to format the strings using variables.
Axis provides a single class org.apache.axis.i18n.Messages
that manages both ResourceBundle and MessageFormat classes.
Messages methods are:
public static java.util.ResourceBundle getResourceBundle();
public static String getMessage(String key) throws java.util.MissingResourceException;
public static String getMessage(String key, String var) throws java.util.MissingResourceException;
public static String getMessage(String key, String var1, String var2) throws java.util.MissingResourceException;
public static String getMessage(String key, String[] vars) throws java.util.MissingResourceException;
Axis programmers can work with the resource bundle directly via a call
to Messages.getResourceBundle()
,
but the getMessage()
methods should be used instead for two reasons:
Messages.getMessage("myMsg00");
Messages.getResourceBundle().getString("myMsg00");
getMessage
methods enable messages with variables.myMsg00=This is a string.
Messages.getMessage("myMsg00");
If you have a message with variables, use the syntax
"{X}"
where X
is
the number of the variable, starting at 0. For example:
myMsg00=My {0} is {1}.
Messages.getMessage("myMsg00","name", "Russell");
You could also call the String array version of getMessage:
Messages.getMessage("myMsg00", new String[] {"name", "Russell"});
The String array version of getMessage
is all that is necessary, but the vast majority of messages will have 0,
1 or 2 variables, so the other getMessage
methods are provided as a convenience to avoid the complexity of the String
array version.
Note that the getMessage methods throw MissingResourceException if the resource cannot be found. And ParseException if there are more {X} entries than arguments. These exceptions are RuntimeException's, so the caller doesn't have to explicitly catch them.
The resource bundle properties file is org/apache/axis/i18n/resource.properties.
See Also: Test and Samples Structure
Editor's Note: We need more effort to streamline and simplify the addition of tests. We also need to think about categorizing tests as the test bucket grows.If you make changes to Axis, please add a test that uses your change. Why?
Some general principles:
One way to build a test is to "cut and paste"
and existing tests, and then modify the test to suit your needs.
This approach is becoming more complicated as the different kinds of tests
grow.
A good "non-wsdl" test for reference is test/saaj.
java org.apache.axis.wsdl.Wsdl2java -t -s
SequenceTest.wsdl

<wsdl2java url="${axis.home}/test/wsdl/sequence/SequenceTest.wsdl"
output="${axis.home}/build/work"
deployscope="session"
skeleton="yes"
messagecontext="no"
noimports="no"
verbose="no"
testcase="no">
<mapping namespace="urn:SequenceTest2" package="test.wsdl.sequence"/>
</wsdl2java>
As of Axis 1.0, RC1, we have moved to a "componentized" test structure. Instead of having one high-level large recursive function, there are smaller, simple "component" build.xml files in the leaf level of the test/** and samples/** trees.
These "component" files have a common layout. Their primary targets are:
A "sample" test xml file can be found in test/templateTest
If a convention can be reduced to a regular expression match, it can be enforced at build time by updating java/test/utils/TestSrcContent.java.
All that is necessary is to add a pattern to the static FileNameContentPattern array. Each pattern has three parameters:
A reasonable summary of the regular expression notation is provided in the Jakarta ORO javadocs.
You try to run some JUnit tests on an Axis client that invokes a web service, and you always get this exception:
java.lang.ExceptionInInitializerError at org.apache.axis.client.Service.(Service.java:108) ... Caused by: org.apache.commons.logging.LogConfigurationException: ... org.apache.commons.logging.impl.Jdk14Logger does not implement Log at org.apache.commons.logging.impl.LogFactoryImpl.newInstance (LogFactoryImpl.java:555) ...
Actually, the Jdk14Logger does implement Log. What you have is a JUnit classloading issue. JUnit's graphical TestRunner has a feature where it will dynamically reload modified classes every time the user presses the "Run" button. This way, the user doesn't need to relaunch the TestRunner after every edit. For this, JUnit uses its own classloader, junit.runner.TestCaseClassLoader. As of JUnit 3.8.1, confusion can arise between TestCaseClassLoader and the system class loader as to which loader did or should load which classes.
There are two ways to avoid this problem.
# # The list of excluded package paths for the TestCaseClassLoader # excluded.0=sun.* excluded.1=com.sun.* excluded.2=org.omg.* excluded.3=javax.* excluded.4=sunw.* excluded.5=java.* excluded.6=org.w3c.dom.* excluded.7=org.xml.sax.* excluded.8=net.jini.*
Copy this file, preserving the directory path, into another location, e.g. deployDir. So the copied properties file's path will be deployDir/junit/runner/excluded.properties. Add an extra entry to the end of this file:
excluded.9=org.apache.*
Edit your classpath so that deployDir appears before junit.jar. This way, the modified excluded.properties will be used, rather than the default. (Don't add the path to excluded.properties itself to the classpath.)
This fix will prevent the commons-logging exception. However, other classloading problems might still arise. For example:
Dec 10, 2002 7:16:16 PM org.apache.axis.encoding.ser.BeanPropertyTarget set SEVERE: Could not convert [Lfoo.bar.Child; to bean field 'childrenAsArray', type [Lfoo.bar.Child; Dec 10, 2002 7:16:16 PM org.apache.axis.client.Call invoke SEVERE: Exception: java.lang.IllegalArgumentException: argument type mismatch at org.apache.axis.encoding.ser.BeanPropertyTarget.set (BeanPropertyTarget.java:182) at org.apache.axis.encoding.DeserializerImpl.valueComplete (DeserializerImpl.java:284) ...
In this case, you have no choice but to give up on dynamic class reloading and use the -noloading argument.
One other heads-up about JUnit testing of an Axis web service. Suppose you have run JUnit tests locally on the component that you want to expose as a web service. You press the "Run" button to initiate a series of tests. Between each test, all your data structures are re-initialized. Your tests produce a long green bar. Good.
Suppose you now want to run JUnit tests on an Axis client that is connecting to an application server running the Axis web application and with it your web service. Between each test, JUnit will automatically re-initialize your client.
Your server-side data structures are a different matter. If you're checking your server data at the end of each test (as you should be) and you run more than one test at a time, the second and later tests will fail because they are generating cumulative data on the Axis server based on preceding tests rather than fresh data based only on the current one.
This means that, for each test, you must manually re-initialize your web service. One way to accomplish this is to add to your web service interface a re-initialize operation. Then have the client call that operation at the start of each test.
tcpmon
to Monitor Functional Tests.
Here is an easy way to monitor the messages while running
functional-tests
(or all-tests
).
Start up tcpmon listening on 8080 and forwarding to a different port:
java org.apache.axis.utils.tcpmon 8080 localhost 8011Run your tests, but use the forwarded port for the SimpleAxisServer, and indicate that functional-tests should continue if a failure occurs.
ant functional-tests -Dtest.functional.SimpleAxisPort=8011 -Dtest.functional.fail=noThe SOAP messages for all of the tests should appear in the tcpmon window.
tcpmon
is described in more detail in the
Axis User's Guide.
SOAP Monitor
to Monitor Functional Tests.
If you are debugging code that is running as a web application using
a web application server (such as Tomcat) then you may also use the
SOAP Monitor utility to view the SOAP request and response messages.
Start up the SOAP monitor utility by loading the SOAP monitor applet
in your web browser window:
http://localhost:<port>/axis/SOAPMonitor. As you run your tests, the SOAP messages should appear in the SOAP monitor window.
SOAP Monitor
is described in more detail in the
Axis User's Guide.
java org.apache.axis.transport.http.SimpleAxisServer -p 8080In another window, first deploy the service you're testing:
java org.apache.axis.client.AdminClient deploy.wsddThen bring up the JUnit user interface with your test. For example, to run the the multithread test case:
java junit.swingui.TestRunner -noloading test.wsdl.multithread.MultithreadTestCase
log4j.properties
file
is packaged in axis.jar
with reasonable
default settings.
Subsequent items presume changes to these settings.
There are multiple options open to the developer,
most of which involve
extracting log4j.properties
from axis.jar
and modifying as appropriate.
Java
programs from
a command line or script file,
include the JVM option
-Dlog4j.configuration=yourConfigFile
.
CLASSPATH
such that
your version of log4j.properties
appears
prior to axis.jar
in the CLASSPATH
.
ant
(this includes building Axis and running it's tests),
set the environment variable ANT_OPTS
to -Dlog4j.configuration=yourConfigFile
.
src/log4j.properties
directly. Be sure NOT to commit your change(s).
log4j.rootCategory
priority to
DEBUG
.
DEBUG
(The log4j.properties
file in Axis defines two appenders:
CONSOLE
and LOGFILE
).
log4j.rootCategory
priority to
INFO
or higher.
log4j.logger.logger.name
priority to
DEBUG
for the loggers that you are interested in.
DEBUG
(The log4j.properties
file in Axis defines two appenders:
CONSOLE
and LOGFILE
).
grep
to
search for them in log messages.
System.out.println
or
System.err.println
should be avoided.
Developers may be tempted to use System.out.println
while debugging or analyzing a system.
If you choose to do this, you will need to disable the
util/TestSrcContent
test,
which enforces avoidance of
System.out.println
and System.err.println
.
It follows that you will need to remove your statements
before checking the code back in.
As an alternative,
we strongly encourage you to
take a few moments and introduce debug statements:
log.debug("reasonably terse and meaningful message")
.
If a debug message is useful for understanding a problem now,
it may be useful again in the future to you or a peer.
The kit comes as a zip file which you should unzip into a directory of your choosing. The installation instructions are in the JAX-RPC Release Notes document which is stored in the docs directory. If you open the index.html file in the docs directory using a web browser, you'll see a list of all the documents supplied with the kit.
Note that the kit includes the JavaTest test harness which is used for running the compatibility tests.
If any more information is needed about running these tests, please add it here!

UD for Spanish
Tokenization and Word Segmentation
- In general, words are delimited by whitespace characters. Description of exceptions follows.
- According to typographical rules, many punctuation marks are attached to a neighboring word. We usually tokenize them as separate tokens (words) with the exception of abbreviations such as etc. “etc.” which are kept as one token with the period.
- There are two main classes of multi-word tokens:
- Contractions of prepositions and definite articles. Example: al = a + el “to the”, del = de + el “of the”.
- Certain verb forms (infinitives, imperatives, present participles) are writen together with object clitic pronouns, while with other verb forms the clitics are written as separate words. Examples: convertirse = convertir + se “to become” (lit. “to convert itself”), hacerlo “to do it”.
Morphology
Tags
- Spanish uses all 17 universal POS categories, including particles (PART).
- The only word to be tagged as particle is no “not”.
- TODO: rules for the PRON vs. DET distinction.
- Spanish auxiliary verbs (AUX) are:
- ser and estar “to be”, used as copulas
- ser “to be” for the passive (la sentencia fue publicada “the sentence was published”)
- estar “to be” for the progressive (mis hijos están estudiando inglés “my children are studying English”)
- haber “to be” for the perfect tenses (ha venido hoy “he came today”)
- There are four main (de)verbal forms, distinguished by the UPOS tag and the value of the VerbForm feature:
Nominal Features
- Nominal words (NOUN, PROPN and PRON) have an inherent Gender feature with one of two values:
Masc
orFem
.- The following parts of speech inflect for
Gender
because they must agree with nouns: ADJ, DET. Only a subset of adjectives can inflect for gender, with the suffix -o indicating the masculine and -a the feminine. A large group of adjectives (e.g. grande “big” or feliz “happy”) have just one form regardless of the gender of the modified noun. These adjectives have the gender feature empty.
- The following parts of speech inflect for
- The two values of the Number feature are
Sing
andPlur
. The following parts of speech inflect for number: NOUN, PROPN, PRON, ADJ, DET, VERB, AUX (finite and participles). - Case has 4 possible values:
Nom
,Dat
,Acc
,Com
. It occurs only with personal pronouns (PRON). The “case” (i.e., role w.r.t. predicates or other phrases) of other nominals is expressed using prepositions, not morphologically. - Definite has 2 values:
Ind
,Def
. It is used to distinguish the indefinite and definite articles (DET).
Degree and Polarity
- Degree applies to adjectives (ADJ) and adverbs (ADV) and has one of three possible values:
Pos
,Cmp
,Abs
. The absolute superlative is marked morphologically on adjectives. Otherwise, the comparative and superlative of most adjectives is formed periphrastically, andDegree=Cmp
is only used with a few irregular forms. - Polarity is used to mark the negative particle no, i.e., only the
Neg
value is used.
Verbal Features
- Finite verbs always have one of four values of Mood:
Ind
,Imp
,Sub
andCnd
. - Finite verbs can have one of four values of Tense:
Past
,Imp
,Pres
,Fut
.- Imperative and conditional forms do not have the
Tense
feature. (In Spanish grammar, the conditional is itself often classified as a tense. However, it is a mood in Universal Dependencies.) - The
Tense
feature is also used with the past participles (venido “come”).
- Imperative and conditional forms do not have the
- The Aspect feature is currently not used in Spanish.
It is not needed for the imperfect past tense because UD has the special value
Tense=Imp
. And it is not needed for the perfect tenses because they are constructed periphrastically. - The Voice feature is not used in Spanish because the passive voice is expressed periphrastically.
Pronouns, Determiners, Quantifiers
- PronType is used with pronouns (PRON) and determiners (DET).
- NumType is used with numerals (NUM), adjectives (ADJ) and determiners (DET).
- The Poss feature marks possessive personal determiners (e.g. mi “my”), possessive personal pronouns (e.g. mío “mine”), and possessive interrogative or relative determiners (e.g. cuyo “whose”).
- The Reflex feature is always used together with
PronType=Prs
and it marks reflexive pronouns (me, te, se, nos, os). Note that their forms in the first and second person are ambiguous with irreflexive accusative forms, and theReflex
feature must be decided by context. - Person is a lexical feature of personal pronouns (PRON) and has three values,
1
,2
and3
. With personal possessive determiners (DET), the feature actually encodes the person of the possessor. Person is not marked on other types of pronouns and on nouns, although they can be almost always interpreted as the 3rd person. - The Polite feature distinguishes informal second-person pronouns (tú, vosotros,
Polite=Infm
) from the formal usted, ustedes (Polite=Form
). - There is one layered feature, Number[psor]. It appears with possessive determiners and encodes the lexical number of the possessor. The extra layer is needed to distinguish this lexical feature from the inflectional number that marks agreement with the modified (possessed) noun.
Other Features
Syntax
Core Arguments, Oblique Arguments and Adjuncts
- Nominal subject (nsubj) is a bare noun phrase without preposition. If it is a personal pronoun, it must be in the nominative form (note however that Spanish is a pro-drop language, where pronominal subjects can be omitted).
- Direct nominal object (obj) is either a bare noun phrase (for inanimate objects) or a prepositional phrase with the preposition a (for animate objects) or a personal pronoun in the accusative form.
- Extra attention has to be paid to the reflexive pronoun se. It can function as:
- Core object (obj or iobj): él se vio en el espejo “he sighted himself in the mirror.”
- Reciprocal core objects (
obj
oriobj
): se besaron “they kissed each other.” - Reflexive passive (expl:pass): se celebran los cien años del club “hundred years of the club are celebrated” (lit. “celebrate themselves”); se dice que la escribió en París “it is said that he wrote it in Paris.”
- Inherently reflexive verb, cannot exist without the reflexive clitic, and the clitic cannot be substituted by an irreflexive pronoun
or a noun phrase. In many cases, an irreflexive counterpart of the verb actually exists but its meaning is different because it
denotes a different action performed by the agent.
In accord with the current UD guidelines, we label the relation
between the verb and the clitic as expl:pv, not
compound
. Example: se trataba de un negocio nuevo “the matter is a new contract.”
- In passive clauses, the subject is labeled with nsubj:pass or csubj:pass, respectively.
- The auxiliary verb in periphrastic passive is labeled aux:pass.
Non-verbal Clauses
- The copula verbs ser and estar (be) are used in equational, attributional, locative, possessive and benefactory nonverbal clauses.
- Existential clauses use a different verb, hay (be), and the entity whose existence is asserted is its object: hay algo para comer “there is something to eat.”
Relations Overview
- The following relation subtypes are used in Spanish:
- acl:relcl for relative clauses
- nsubj:pass for nominal subjects of passive verbs
- csubj:pass for clausal subjects of passive verbs
- aux:pass for passive auxiliaries
- The following relation types are not used in Spanish at all: clf, dislocated
Treebanks
There are three Spanish UD treebanks:

Date memoizes some instance methods using metaprogramming to wrap the methods with one that caches the result in an instance variable.
If a Date is frozen but the memoized method hasn’t been called, the first call will result in a frozen object error since the memo instance variable is uninitialized.
Work around by eagerly memoizing before the first freeze.
Ruby 1.9 uses a preinitialized instance variable so it’s unaffected. This hack is as close as we can get to feature detection:

Regular readers know that here at Hooting Yard we like to keep abreast of important doings in the world of petulant Canadian pop songstresses. That being so, it did not escape our attention that a new acoustic version of Jagged Little Pill by Alanis Morissette is being issued as a “ten year anniversary commemorative edition”.
Next year will see the twentieth anniversary of the publication of two ground-breaking books, Stab Your Employer and Smooching With Istvan. These were early collaborations between Max Décharné and Frank Key and are, just like Dobson's pamphlets, sadly out of print. Following Ms Morissette's example, I think that twentieth anniversary commemorative acoustic editions would be a splendid idea. I know what you're thinking—these were written works, not musical ones. Hell, we won't let that stop us! Max and I have already arranged for a series of meetings to thrash out the details of the project.
Meanwhile, admirers of the woman Johnny Esposito calls “Her Shrillness”, if there are any, ought to visit the Alanis Morissette Random Lyrics Generator.


Mancini's Italy visit 'wounded' Venice
by BeSoccerRoberto Mancini's Italian national football team travelled to flood-hit Venice on Saturday, the morning after extending their winning streak in Euro 2020 qualifying.
The FIGC delegation visited several businesses damaged by the flooding, and chatted with Venetians, volunteers and police.
"Venice will overcome this too. Like an athlete who suffers a serious injury and then gets up again," said delegation chief Gianluca Vialli.
"Venice is a wounded city, but it is strong as well as being wonderful, and has shown great character and an extraordinary ability to stand up," said Gravina.

Italy coach Mancini later signed autographs as 200 fans were allowed to watch the team's training session at the city's 'Taliercio' sports centre, which had initially been planned behind closed doors.
The visit also coincides with the unveiling of a partnership agreement between the four-time world champions and Venice Airport, later on Saturday.
The Azzurri will on Sunday travel to Palermo for their final Euro 2020 qualifying game against Armenia.
The Azzurri have bounced back impressively after failing to qualify for last year's World Cup for the first time since 1958.
Italy registered a record 10th straight win as they eased past Bosnia and Herzegovina 3-0 in Zenica on Friday.

PLANET SICK-BOY: http://www.sick-boy.com
It seems to be an annual tradition this time of year. I'm not talking about Christmas shopping or trimming the tree or even packing yourself full of turkey and pie. The custom I refer to is that of heaping oodles of undeserving praise on a small, independent foreign film. Last year, it was the Brazilian festival fave Central Station, which nabbed two Oscar nominations (for Best Actress and Best Foreign Film). This year, it's Pedro Almodóvar's All About My Mother.
Don't get me wrong – it's not a bad movie at all. In fact, it's better than Central Station. But a Best Director win at Cannes? Two European Film Award nominations (Picture and Actress)? And five-star review after five-star review? I just don't get it. I would have to use two hands to count the number of superior films in competition at Cannes. Better than Kikujiro? Not a chance in hell. Among other favorites, Almodóvar beat David Lynch, Peter Greenaway, Jim Jarmusch, Atom Egoyan, John Sayles, Michael Winterbottom and Tim Robbins for the Best Director award.
The film centers around a woman in her late thirties named Manuela (Cecilia Roth – think Deborah Kara Unger in about ten years). She's a hospital nurse and single mom with a seventeen-year-old son named Esteban (Eloy Azorín) who dreams of becoming a writer. As the picture opens, Manuela and Esteban watch a dubbed version of All About Eve, discussing the translation of its title into Spanish (so you'll be watching English subtitles of an American film dubbed in Spanish – oy vey!). For Esteban's birthday, the two take in a stage performance of A Streetcar Named Desire, but he is killed in an accident trying to get an autograph after the show.
This is where Almodóvar (Live Flesh) shines, tactfully blending scenes from both Eve and the stage version of Streetcar to underscore the emotion of his characters. Add to that a nifty ironic twist early on involving organ donation that I won't reveal here, even though I've heard he used a similar theme in The Flower of My Secret (which I've never seen). The use of Streetcar is serendipitous as Manuela actually played Stella several years ago in a Barcelona production, opposite a Kowalski that became Esteban's father. She always told her son that his father died before he was born but in reality, Manuela took off for Madrid, pregnant with Esteban and neglecting to tell the father.
All About My Mother, an obvious homage to the title of All About Eve, is basically the story of Manuela's attempt to track down the father of her child in Barcelona, reversing her journey from seventeen years ago. She meets many zany characters along the way, including a pregnant nun (Penélope Cruz), a transsexual (Antonia San Juan), a junkie (Candela Peña) and an actress (Marisa Paredes). Each woman helps to demonstrate a powerful quote from the film - `Women will do anything to avoid being alone.'
Mother, like other Almodóvar films, is a non-stop visual assault of bright, beautiful colors (his Live Flesh cinematographer Affonso Beato is back here).  It plays like a cheesy Spanish soap opera that you might stumble upon flipping through cable stations. I have a feeling that guy in the giant bee costume may be more entertaining. Alberto Iglesias provides the acoustic-heavy score.

Mathmatically, a proper vertex coloring of an undirected graph G=(V,E) is a map c: V -> S such that c(u) != c(v) whenever there exists an edge (u,v) in G. The elements of set S are called the available colors. The problem is often to determine the minimum cardinality (the number of colors) of S for a given graph G or to ask whether it is able to color graph G with a certain number of colors. For example, how many color do we need to color the United States on a map in such a way that adjacent states have different color? A compiler needs to decide whether variables and temporaries could be allocated in fixed number of registers at some point. If a target machine has K registers, can a particular interference graph be colored with K colors? (Each vertex in the interference graph represents a temporary value; each edge indicates a pair of temporaries that cannot be assigned to the same register.)
Another example is in the estimation of sparse Jacobian matrix by differences in large scale nonlinear problems in optimization and differential equations. Given a nonlinear function F, the estimation of Jacobian matrix J can be obtained by estimating Jd for suitable choices of vector d. Curtis, Powell and Reid [9] observed that a group of columns of J can be determined by one evaluation of Jd if no two columns in this group have a nonzero in the same row position. Therefore, a question is emerged: what is the number of function evaluations need to compute approximate Jacobian matrix? As a matter of fact this question is the same as to compute the minimum numbers of colors for coloring a graph if we construct the graph in the following matter: A vertex represents a column of J and there is an edge if and only if the two column have a nonzero in the same row position.
However, coloring a general graph with the minimum number of colors (the cardinality of set S) is known to be an NP-complete problem [30]. One often relies on heuristics to find a solution. A widely-used general greedy based approach is starting from an ordered vertex enumeration v1, ..., vn of G, to assign vi to the smallest possible color for i from 1 to n. In section Constructing graph algorithms with BGL we have shown how to write this algorithm in the generic programming paradigm. However, the ordering of the vertices dramatically affects the coloring. The arbitrary order may perform very poorly while another ordering may produces an optimal coloring. Several ordering algorithms have been studied to help the greedy coloring heuristics including largest-first ordering, smallest-last ordering and incidence degree ordering.
In the BGL framework, the process of constructing/prototyping such a ordering is fairly easy because writing such a ordering follows the algorithm description closely. As an example, we present the smallest-last ordering algorithm.
The basic idea of the smallest-last ordering [29] is as follows: Assuming that the vertices vk+1, ..., vn have been selected, choose vk so that the degree of vk in the subgraph induced by V - {vk+1, ..., vn} is minimal.
The algorithm uses a bucket sorter for the vertices in the graph where bucket is the degree. Two vertex property maps, degree and marker, are used in the algorithm. The former is to store degree of every vertex while the latter is to mark whether a vertex has been ordered or processed during traversing adjacent vertices. The ordering is stored in the order. The algorithm is as follows:
namespace boost { template <class VertexListGraph, class Order, class Degree, class Marker, class BucketSorter> void smallest_last_ordering(const VertexListGraph& G, Order order, Degree degree, Marker marker, BucketSorter& degree_buckets) { typedef typename graph_traits<VertexListGraph> GraphTraits; typedef typename GraphTraits::vertex_descriptor Vertex; //typedef typename GraphTraits::size_type size_type; typedef size_t size_type; const size_type num = num_vertices(G); typename GraphTraits::vertex_iterator v, vend; for (boost::tie(v, vend) = vertices(G); v != vend; ++v) { put(marker, *v, num); put(degree, *v, out_degree(*v, G)); degree_buckets.push(*v); } size_type minimum_degree = 1; size_type current_order = num - 1; while ( 1 ) { typedef typename BucketSorter::stack MDStack; MDStack minimum_degree_stack = degree_buckets[minimum_degree]; while (minimum_degree_stack.empty()) minimum_degree_stack = degree_buckets[++minimum_degree]; Vertex node = minimum_degree_stack.top(); put(order, current_order, node); if ( current_order == 0 ) //find all vertices break; minimum_degree_stack.pop(); put(marker, node, 0); //node has been ordered. typename GraphTraits::adjacency_iterator v, vend; for (boost::tie(v,vend) = adjacent_vertices(node, G); v != vend; ++v) if ( get(marker, *v) > current_order ) { //*v is unordered vertex put(marker, *v, current_order); //mark the columns adjacent to node //It is possible minimum degree goes down //Here we keep tracking it. put(degree, *v, get(degree, *v) - 1); minimum_degree = std::min(minimum_degree, get(degree, *v)); //update the position of *v in the bucket sorter degree_buckets.update(*v); } current_order--; } //at this point, get(order, i) == vertex(i, g); } } // namespace boost
