[jboss-user] [EJB 3.0] - Stateful session with remote client problem

[jdware]

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
