NoClassDefFoundError HeirarchicalLoaderRepository3

wallayta Dec 10, 2006 11:39 AM

I was using JBoss AOP load-time with JDK1.4. Now trying to use it with jrockit-R26.4.0-jdk1.5.0_06 I get the following error :

java.lang.NoClassDefFoundError: org/jboss/mx/loading/HeirarchicalLoaderRepository3 at org.jboss.aop.deployment.JBossScopedClassLoaderHelper.isScopedClassLoader(JBossScopedClassLoaderHelper.java:64) at org.jboss.aop.deployment.JBossScopedClassLoaderHelper.ifScopedDeploymentGetScopedParentUclForCL(JBossScopedClassLoaderHelper.java:44) at org.jboss.aop.AspectManager.instance(AspectManager.java:334) at org.jboss.aop.deployment.AspectManagerService$1.transform(AspectManagerService.java:216)

I have download jboss-aop_1.5.2GA and I'm using jbossas-4.0.5GA.
I've tried pluggable-implementor.jar and jrockit-pluggable-implementor.jar from lib-50 but none is working.

I had problem the same. I will test my problem of the granularity(other topic) with the instrumentor of the BEA

When I try to have AOP load-time in jdk-1.4 manner with installed jrockit-1.5 I also get an error about HeirarchicalLoaderRepository3, not a NoClassDefFoundError by a java.lang.ClassCircularityError.

I really don't understand why.

If you want to do load-time with jrockit, you just can't do that in the jdk1.4 manner.
You need to use the native classloader hooks of jrockit.

http://labs.jboss.com/portal/jbossaop/docs/1.5.0.GA/docs/aspect-framework/reference/en/html/running.html#d0e3208

But, since you installed JRockit 1.5, you can also go for the load time instrumentations in the jdk1.5 manner.

First, thank you for posting an your message.

When I posted the first message about this problem I've configured AOP load-time in JDK1.5 plain manner, and I get the specified exception stack trace. I've also tried with the jrockit specific jrockit-pluggable-instrumentor.jar from lib-50 (and modification about MBean code to use AspectManagerService rather than AspectManagerServiceJDK5).

I'd like to precise that when I use load-time for a standalone Java app I've no problem, It's only with JBossAS that I get the error.

I couldn't reproduce this error on my machine.

Are you running "all" or "default" jboss as configuration?

Besides, could you please confirm that you've followed all these steps (http://labs.jboss.com/portal/jbossaop/docs/1.5.0.GA/docs/aspect-framework/reference/en/html/running.html#d0e3174):

1.Copy the jboss-aop-jdk15.deployer file to server/<config-name>/deploy directory
2.Edit jboss-aop-jdk15.deployer/META-INF/jboss-service.xml so that:
mbean code is org.jboss.aop.deploymentAspectManagerService
EnableLoadTimeWeaving is set to true
3.Edit run.sh to increment JAVA_OPTS and JBOSS_CLASSPATH environment variables like this:
JAVA_OPTS="$JAVA_OPTS -Dprogram.name=$PROGNAME \ -Xmanagement:class=org.jboss.aop.hook.JRockitPluggableClassPreProcessor" JBOSS_CLASSPATH="$JBOSS_CLASSPATH:jrockit-pluggable-instrumentor.jar"
