Eclipse and Maven

This one is really stupid, but it had me scratching my head for a long time, so ... in it goes.

I develop mainly on a powerful desktop machine in work. Recently however I was transferring some work to my laptop, so I could potentially work on some problems from home.

When I imported the project I was working on onto the same version of eclipse on my laptop it was producing errors.

We use mvn for our builds, so I did the usual thing, of running

mvn eclipse:clean eclipse:eclipse

Still no luck.

After much head scratching te problem was that I had never initialized my M2_REPO variable within my laptops version of eclipse. Therefore all the M2_REPO based libs that mvn eclipse:eclipse generates, were not pointing to anything.

Very annoying.

Weblogic states

WE had a question on our weblogic status recently. SOme libraries were listed as been in the "Installed" state, as opposed to the usual "Active" state.

Heres a breakdown on the various states in Bea Weblogic:

1. There is no valid deployment state as "Installed".

2.. The deployment state is stored in "weblogic.management.runtime.AppRuntimeStateRuntimeMBean". As per the documentation these are the states:
STATE_ACTIVE, STATE_ADMIN, STATE_FAILED, STATE_NEW, STATE_PREPARED, STATE_RETIRED, STATE_UPDATE_PENDING
This is the link to documentation: http://e-docs.bea.com/wls/docs90/javadocs_mhome/weblogic/management/runtime/AppRuntimeStateRuntimeMBean.html

3. You can also check this runtime MBean on the MBean Reference: http://e-docs.bea.com/wls/docs92/wlsmbeanref/core/index.html

4. I got some known issues where it is stated that "Installed" is a console text string that indicates the LibraryMBean is present in the configuration.The Installed state can be changed by rebooting the domain. The problem can happen unexpectedly. Also the library works fine with Installed state as well.

5. It may be possible that the console is picking up a wrong state for the deployment.

6. We can verify this by using WLST to reach the AppRuntimeStateRuntimeMBean and then get the status.
i) First access the DomainRuntimeMBean using the following link: http://e-docs.bea.com/wls/docs92/config_scripting/nav_edit.html#wp1001225
ii) The DomainRuntimeMBean has the handle to AppRuntimeStateRuntimeMBean. Please check the API docs for the method getAppRuntimeStateRuntime(): http://e-docs.bea.com/wls/docs92/javadocs_mhome/weblogic/management/runtime/DomainRuntimeMBean.html
iii) Then get the module IDs and then access the status using AppRuntimeStateRuntimeMBean.getCurrentState(..).

Please let me know what are the results of this test.

Moreover this seems to be a non-reproduceable issue as we can see this occurs only in Production but not in Test.

Please let me know whether the provided information is sufficient. Also let me know if you face any problems in testing the deployment status using WLST.

svn externals

It often useful to link to an external resource within a svn project.

for instance you may store Wsdl and Xsd files in one location, but your implementation code may need to access it. You don't want to copy and paste it since you will end up with 2 copies to maintain.

for these cases you can use svn externals to link to an external svn directory (note only directories can be linked to, not individual files)

e.g. (I set svn:externals via eclipse)

Use Team> Set Property > [select svn:externals]
Enter the name of the directory link you want, (a revision number if required, e.g. -r123), followed by the remote directory to link to.

wsdl [-r rev] http://svnHost/repos/trunk/MyProject/myDir1/wsdl

xsd [-r rev] http://svnHost/repos/trunk/MyProject/myDir1/xsd

SVN Ignore
Svn can be instructed to ignore certain files etc.

For example when working with eclipse projects you will want to specify that .classpath, and .project files will not be included in svn, checkin's or diff's.

Ignores can be setup globally or per directory.

Global
This can be done via eclipse (in the windows/ preferences/ Team control),

or find your subversion config file. e.g. ~/.subversion/config then edit the following line, e.g.

global-ignores = .project .claspath *.o *.lo *.la #*# .*.rej *.tmproj

Local
cd to project directory,
svn propset svn:ignore "target/*

This should ignore the target directory (e.g. for maven builds)

ALSB install problems

On of our servers was throwing up an exception, while trying to start the Adminserver

Search jar files for class

Heres a handy little command for searching classes withen jar files (for example when searching all the jars in a war file)

find <dirs> -name '*.jar' -exec jar tvf {} \; > outputfile

THis will produce a list of all files in the jar files outputted to outputfile.

This script below will print out the filename of each jar, and each associated file within.


list=$(find /apps/bea -print | grep .jar)

for el in $list; do

printf "Searching in %s\n" "$el";

case $el in

jar -tf $el | grep com.bea.console.utils.ConsoleRequestListener

;;

esac

done

Jaxb Multiple namespace definitions

I was mildly concerned about the number of namespace definitions that Jaxb was printing every time it marshaleld an Xml document.

I'm using Spring-ws with jaxb bindings. In my definition of the Spring Marshaller I declare the jaxb packages which this marshaller will marshall. Each of these is turned into a namespace definiton on the resulting xml doc.

<bean id="jaxb2Marshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
<property name="contextPath" value="com.company.package1:com.company.package2:com.company.package3:com.company.package4">
</property>
</bean>

Results in

<ns1:request ns1="http://www.company.com/Package1" ns2="http://www.company.com/Package2" ns3="http://www.company.com/Package3" ns4="http://www.company.com/Package4">
<ns1:data>text
</ns1:data>
</request>

This was mildly irritating.

After a bit of searching I find its a 'performance feature' in Jaxb2

https://jaxb.dev.java.net/issues/show_bug.cgi?id=103

So they won't be fixing it.

The alternative from my point of view is to declare multiple marshallers, and use them where appropriate.

<bean id="jaxb2Marshaller1" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
<property name="contextPath" value="com.company.package1">
</property>
</bean>
<bean id="jaxb2Marshaller2" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
<property name="contextPath" value="com.company.package2">
</property>
</bean>
..etc..

Python gotcha

This Seemingly innocuous indentation error in python was annoying me.

Problem invoking WLST - Traceback (innermost last):
(no code object) at line 0
File "C:\apps\installWls.py", line 249
toDeploy = sys.argv[3]
^
SyntaxError: inconsistent dedent

Looking at my code (wlst code to auto deploy application into weblogic server), it was all indented correctly.

Well of course the computer was right. It wasn't indented correctly, but it was no obvious.

The issue was some copy and paste code I took from the internet.

It was indented using spaces, whereas I was using tabs.

Replacing the space indentation with tabs fixed the issue (but its not obvious uinless you set your editor to display non visible characters.

StackoverFlow using spring-ws on weblogic 9.2


We finally got our spring-ws application deployed.

Or so we thought. The next day when we arrived int he code was crashing, and the JMS queue was not been read....

The img to the right shows the non-heap memory growth. Something is not clearing.

Below is the stack trace we get





Edit

Two things to check that might help: (I have not been able to test this now, as I no longer work on this project or for this client.)

* Make sure that you haven't somehow configured a foreign JNDI or foreign JMS server that is self referencing.

* Make sure that you haven't specified a URL when there's no need to specify a URL. (Server side applications and configuration should never specify a URL for a resource unless the resource is in a different cluster. When a resource is located in the same cluster, JNDI lookups should simply be made directly in the cluster's JNDI name-space. The way to ensure that the lookup is direct is simply to use initial contexts that were created without an URL.)

Spring-ws and weblogic incompatibilities

I wrote about incompatible versions of spring before resulting in cryptic error messages.

Well my solution there wasn't the full picture, if you are running xml /web servicse on weblogic. (Though at least this time I recognised the error as incompatible jars)

I was getting various different non-intuitive errors when trying to run a spring-ws application on weblogic 9.2.1.

e.g.
<User defined listener org.springframework.web.context.ContextLoaderListener failed: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'webServiceTemplateProxy' defined in class path resource [com/meteor/provisioning/servicecategory/serviceBeansSpringConfig.xml]: Cannot resolve reference to bean 'webServiceTemplate' while setting bean property 'target'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean withname 'webServiceTemplate' defined in class path resource [com/meteor/provisioning/servicecategory/serviceBeansSpringConfig.xml]: Cannot resolve reference to bean 'messageFactory' while setting bean property 'messageFactory'; nested exception is org.springframework.beans.factory.BeanCreationException:

After a lot of effort and with help from various postings (namely here, and here ), I managed to track down the various xml jars I needed to override weblogics internal jars.

These include the following taken from my maven pom.xml file. (Note I can't guarantee that this is the full list, or that this list does not contain jars that are in fact not needed. All I can say is that this list worked for me). BTW some of these I had to manually install in my maven repository myself, as I couldn't find them on remote repositories.

The problem is with weblogic (various versions, 9.2, 9.2.1, 8.1, and I believe 10) and spring-ws. Weblogic comes with various xml libraries, most of which have been superseded by newer versions. Spring-ws requires some of these newer jars (e.g. saaj, and axiom), which in turn refer to newer versions of base xml libraries. Thus you have an incompatibility.


Also from Arjens post you need to update your weblogic.xml file, adding the following, to instruct weblogic to take the supplied files before already installed files int he weblogic system
<container-descriptor>
<prefer-web-inf-classes>true</prefer-web-inf-classes>
</container-descriptor>


BTW I was only able to finally fix the problem by firstly deploying it on Tomcat.

The above example works much easier in Tomcat, since it doesn't have any conflicting xml libraries causing grief. By actually getting the application running in tomcat, I was able to (relatively) quickly find out which jars I needed.

Tomcat would throw a NoClassDefFound exception when it came across a jar it didn't have. This doesn't happen in weblogic since it has xml jars, just the wrong versions. Once I had the application running in tomcat, I knew I had found all the required jars. When I moved it back to weblgoic the problem was solved.

Note: unlike Ajens post, I required saaj1.3 in my WEB-INF/lib folder

Actually I wasn't quite there yet, (see next post), but I this had finally sorted out this problem

Failure executing javac

There's nothing quite so deflating as seeing a message like the following

[INFO] ------------------------------------------------------------------------
[ERROR] BUILD FAILURE
[INFO] ------------------------------------------------------------------------
[INFO] Compilation failure
Failure executing javac, but could not parse the error:
An exception has occurred in the compiler (1.5.0_06). Please file a bug at the Java Developer Connection (http://java.sun.com/webapps/bugreport) after checking the Bug Parade for duplicates. Include your program and the following diagnostic in your report. Thank you.
com.sun.tools.javac.code.Symbol$CompletionFailure: file javax\xml\ws\WebServiceClient.class not found


You really begin to wonder if you're doing something very wrong.
Fortunately you're not, and there is a quick and easy workaround.
This it turns out is a bug with javac on windows

My quick solution. Compile using cygwin. (If you haven't got cygwin, simply download setup.exe, and install)

This worked fine. My details was using jdk 1.5.0_06 (the bug has been reported on 1.5.0_04, and seen on 1.6 as well), on windows xp building using maven 2.0.8. Running my maven script in a cygwin bash window worked fine.

spring versions

Beware of mixing tools with different Spring versions.

I was using spring ws 1.5.3, and getting the following error

java.lang.NoSuchMethodError: org.springframework.util.ResourceUtils.toURI(Ljava/net/URL;)Ljava/net/URI;
....

Problem is that I had spring 2.0.x on my path, but spring-ws requires spring 2.5.x

Once I updated to using spring 2.5.x the problem was solved.

Could be a nasty problem, since the error message could easily lead you on a wild goose chase

Maven multiple source directories

By default with maven you can only specify a single source directory. Not very flexible. The following pluggin expands this, allowing you to specify many src dirs.

Heres a sample from the pom.xml

<build>


<build>
   <!-- Replaced with build-helper-maven-plugin below to allow for multiple source directories
       <sourceDirectory>${basedir}/src/main/java</sourceDirectory>
   -->
   <testSourceDirectory>
       ${basedir}/src/test/java
   </testSourceDirectory>
   <plugins>
       <plugin>
           <artifactId>maven-compiler-plugin</artifactId>
           <configuration>
               <source>1.5</source>
               <target>1.5</target>
               <debug>false</debug>
           </configuration>
       </plugin>
       <plugin>
           <groupId>org.codehaus.mojo</groupId>
           <artifactId>build-helper-maven-plugin</artifactId>
           <version>1.1</version>
           <executions>
               <execution>
                   <id>add-source</id>
                   <phase>generate-sources</phase>
                   <goals>
                       <goal>add-source</goal>
                   </goals>
                   <configuration>
                       <sources>
                           <source>
                               ${basedir}/src/main/java
                           </source>
                           <source>
                               ${basedir}/src/types/java
                           </source>
                       </sources>
                   </configuration>
               </execution>

Why spring rocks in a nuthell

http://www.jroller.com/kdonald/entry/the_essence_of_spring

Injecting enums in Spring beans
Found this while searching for how to insert enums into Spring beans from the xml config file (basically you just put the enum value directly in the xml file, http://www.jroller.com/kdonald/entry/spring_hidden_gem_support_for)

PropertyPlaceholderConfigurer doesn't work with XmlBeanFactory

SImple gotcha.

I was using Spring and the PropertyPlaceholderConfigurer. This simply allows you to populate your spring config file with values from a properties file at runtime. For me the properties file is loaded from the classpath (using the classpath: prefix). this is then stored in a seperate config folder whihc is shared between all projects, thus allowing us to update the config file with needing to redploy the complete application again.

e.g.

<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>jms.properties</value>
<ref bean="getNetworkServicePropertyFile" />
</list>
</property>
</bean>
<bean id="test" class="com.meteor.provisioning.Test">
<property name="jmsTemplate" value="${jms.receiveTimeout}" />
</bean>


I write a simple class to instantiate this from a Unit test.


public static BeanFactory getSpringContext() {
springConfigFile = System.getProperty("SpringConfig", springConfigFile);
if (_beanFactory == null) {
Resource resource = new ClassPathResource(springConfigFile);
//_beanFactory = new XmlBeanFactory(resource);
}
return _beanFactory;
}
public static Object getBean(String bean){
return getApplicationContext().getBean(bean);
}

and finally a test case

public class Test {
private String jmsTemplate;

public void setJmsTemplate(String jmsTemplate) {
this.jmsTemplate = jmsTemplate;
System.out.println("jmsTemplate = "+jmsTemplate);
}

@org.junit.Test
public void doTest(){
Utils.getBean("test");
}

}



It didn't work. The PropertyPlaceholderConfigurer, wasn't updating the internal spring file with values from the jms.properties. The jmsTemplate value was been returned as ${jms.receiveTimeout}

Turns out that only ApplicationContext files do the replacement. A quick update to

public static ApplicationContext getApplicationContext() {
springConfigFile = System.getProperty("SpringConfig", springConfigFile);
if (_beanFactory == null) {
_beanFactory = new ClassPathXmlApplicationContext(springConfigFile);
}
return _beanFactory;
}

fixed the problem. Thanks also to http://francisoud.blogspot.com/2007/06/spring-property-placeholder.html

Converting Video and Audio

This is going to be an ongoing article as I try and locate the best free tools for the job.
Good general reference site is Afterdawn, and their forums

Ok firsts.
Copy/ Backup DVD
DVDShrink is an invaluable tool for compressing and copying and backing up DVD's to a directory on your pc. It can copy full DVD, or you can remaster the contents and remove copyright protection notices/ menus/ trailers etc.
There's a handy guide on MrBass

Some newer DVD's have copy protection which DVDShrink can't handle, then DVDDecrypter can sometimes help. If you want to burn the result onto a backup DVD (instead of just storing it on your pc) you probably will still need to run DVDShrink on the ripped files to reduce them enough to fit on your backup DVD. (Unless your DVD burner can burn multi layer)

Burning Images
ISOBurn for buringn images

Video Converting formats

handbrake. This si a great tool (oringally only on Mac, but on Windows and Linux now), for ripping dvd's to mp4, or H264 formats. Doesn't convert formats from what I can see

Super tool for convert all sorts of types

Audio

Switch is a tool. I've just tried to convert 3 mp4's. Converted for 2 of them, didn't work on one.
