I tried a different approach to this by dynamically adding interceptors to the stack. I can get a reference to the InterceptorFactory object and list the two default interceptors in it. But how can I add interceptors? The addInterceptor() method is located in the class JBossInterceptorStackFactory, but how can I get an instance of this? If I try to cast the InterceptorFactory I got it throws a ClassCastException, because it is of type "$proxy242". The class show this when I print it: "MBeanProxyExt[portal:service=InterceptorStackFactory,type=Cms], $Proxy242" I get the object using the following (which seems to be working when using the interface and not the implementation class): MBeanServer server = MBeanServerLocator.locate(); | m_mbeanProxy = MBeanProxyExt.create(m_proxyInterface, m_objectName, server); View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4083298#...
