Hi
I have tried to execute following sample JBOSS AOP application, my aspect(MyAspect .java)
class is never gets invoked. Can someone helpe me to resolve this issue.
For the attached files, aspect class is never invoked.
When I have added the following property @ build.xml at run-load-time target,
-----------------------------------------------------------------------------------
sysproperty key="jboss.aop.class.path" value="${build.classes.dir}"/
-----------------------------------------------------------------------------------
I am getting the following Exception
