In EJB2.1 and JBoss 4.0.x I put it on Client's CP and added the Interceptor in standardjboss.xml or jBoss.xml. But in EJB3 and JBoss4.2.x the ClientInterceptor must be availiable on Servers CP when I add the new ClientInterceptor-Class in ejb3-interceptors-aop.xml in delopy directory! Is there another way to define an new Client-Interceptor as in ejb3-interceptors-aop.xml? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4191794#...
