Hi,
I'm using jboss-4.0.5.GA and jboss-EJB-3.0_RC9_Patch_1 and I'm getting an error
when the client does the context lookup. My local interface works fine.
I'm getting a "java.lang.ClassNotFoundException:
[Lorg.jboss.aop.advice.Interceptor". I found that class in jboss-aop-jdk50.jar and I
know that it is in my classpath.
thanks in advance,
john
