[jboss-user] [JBoss AOP] - Re: ClassNotFoundException: org.jboss.injbossaop.lib.Example

[forumer]

I am continuing to have problems making injboss example to work and would appreciate any help.

This time I started with a fresh version of JBoss 4.2.2 and JBoss-aop-2.1.3.GA

ran the default ant task in script under C:\Downloads\JBoss\jboss-aop-2.1.3.GA\jboss-40-install\jboss-aop-jdk50.deployer after modifying properties to point to JBoss instance


In C:\jboss-4.2.2.GA\server\all\deploy\jboss-aop-jdk50.deployer\META-INF\jboss-service.xml

<attribute name="EnableLoadtimeWeaving">true</attribute>

copied pluggable-instrumentor.jar from jboss-aop-2.1.3.GA\lib to C:\jboss-4.2.2.GA\bin

set JAVA_OPTS=%JAVA_OPTS% -Dprogram.name=%PROGNAME% -javaagent:C:\jboss-4.2.2.GA\bin\pluggable-instrumentor.jar in run.bat

ran the deploy-basic-lt-war-in-jar task for the examples\injboss

C:\jboss-4.2.2.GA\bin>run -c all

Also seeing the following on console:
