Hi there, after moving my webclient from JBoss (5.0.1.GA) to separate servlet container (tomcat), I got java.lang.ClassCastException | com.sun.corba.se.impl.javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:229) when accessing my EJBs via the web-client (in PortableRemoteObject.narrow). After hours of frustrating trial&error, I copied the whole content of [jboss-installation-dir]/client to the WEB-INF/lib directory of my web application and everything worked fine. But having the hole bunch of jars from jboss's client directory in my web application's WEB-INF/lib directory is definitely not what I want. So can somebody point me on a piece of docu where I can find out which jars from the client directory I really need?
