More information,
I had this working with JBoss 4.0.1 back in late Dec.
when I was doing research.

I am trying to working on adding this to our production branch.

Please re-read the documentation.  You need to put the jdk14-pluggable-transformer.jar and also the generated jboss-classloader-transformer.jar in your bootclasspath.  See section

10.3.2 JBoss 4.x and JDK 1.4


BTW, the reason we did this is because the old way was not reliable as it relied on a JBoss specific classloader.  Tomcat and other applications use their own customer classloader in many situations which resulted in things like JSPs not getting aspectized.

BTW, the old EnableTransformer switch still works.  So, if you use EnableTransformer instead of EnableLoadtimeWeaving, you can still use the old way.

I do not know how I missed that.  I will give it a try.
Thanks

I try to run create-pluggable-jboss-classloader.bat

I get a memory could not be "written" when trying to run the line after
rem Run instrumented program

I click OK and it goes on a produces jboss-classloader-transformer.jar

I have done the rest of the items in the doc and still do not get my aspect to run.

Are there any class loading or packaging issues.  My ejb is packaged in it's own jar and is in the deploy directory

The jboss-aop.xml is in the deploy directory

The aspects are packaged in a jar that is in the lib directory

That bat file line look like 
%JAVA_CMD%  -Xbootclasspath/p:%AOP_FILES% -classpath %USER_CLASSPATH% %AOPPATH% %AOPCLASSPATH% %MAINCLASS_AND_ARGS%

I can not find anything def on MAINCLASS_AND_ARGS

It works fine for me. Don't worry too much about the contenys of  create-pluggable-jboss-classloader.bat. It sounds like it is creating the file as expected

Did you do these steps from the docu:

anonymous wrote : 
  |  This will create a jboss-classloader-transformer.jar. Copy this jar to the bin/ directory of your JBoss Application server distribution.
  | 
  | Next, you need to copy the jdk14-pluggable-instrumentor.jar from the lib/ directory of your JBoss AOP distribution to the bin/ directory of your JBoss application server installation. Next edit run.sh or run.bat (depending on what OS you're on) and add the following to the JAVA_OPTS environment variable
  | 
  | 
  |   | JAVA_OPTS="$JAVA_OPTS -Dprogram.name=%PROGNAME% -Xbootclasspath/p:jboss-classloader-transformer.jar:jdk14-pluggable-instrumentor.jar"
  |   |          
  |   | 
  | 
  | After modifying JAVA_OPTS and setting the EnableLoadtimeWeaving to true, then you should be ready to go.

I have add those items to java_opts and added the jars to the bin directory and EnableLoadtimeWeaving=true.  And still not executed my aspects.

I am working on the examples under injboss and not getting the aspects execute.  So there is something miss alined.

Make sure that you add org.jboss.injbossaop to the "Include" attribute of the aspect manager service. Otherwise they get excluded by the org.jboss value put into the Exclude attribute. Entries are comma separated. 

I have enabled this example by default in 1.3.1

there is a typo in your "Include" attribute.  Do you see it?

no.  The only thing I see that I try changing is the . at the end of injbossaop 

I tried both

  | <attribute name="Include">org.jboss.test,org.jboss.injbossaop.</attribute>

OK I got my head out of my

The issue was the bat file.

I pasted the line directly from the tutorial as

  | JAVA_OPTS="$JAVA_OPTS -Dprogram.name=%PROGNAME% -Xbootclasspath/p:jboss-classloader-transformer.jar:jdk14-pluggable-instrumentor.jar"
  | 

I needed to change the : between the two jars to a ;


  | JAVA_OPTS="$JAVA_OPTS -Dprogram.name=%PROGNAME% -Xbootclasspath/p:jboss-classloader-transformer.jar;jdk14-pluggable-instrumentor.jar"
  | 

I change the other things to make it dos base but not that

Thanks again for your help.  I have the injboss examples working and I have my old examples working again
