[jboss-user] [Installation, Configuration & DEPLOYMENT] - Error when narrowing a session bean (remote interface) deplo

Hello forum, I deployed a web application into JBoss 4.2.2 GA, and in this web application, a managed bean will have access to a EJB session bean (remote interface) deployed in the same JBoss server, but I got this error: ERROR [STDERR] java.lang.ClassCastException 20:01:44,775 ERROR [STDERR] at com.sun.corba.se.impl.javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:229) 20:01:44,775 ERROR [STDERR] at javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:137) 20:01:44,775 ......... org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:844) 20:01:44,802 ERROR [STDERR] at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:583) 20:01:44,802 ERROR [STDERR] at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:446) 20:01:44,803 ERROR [STDERR] at java.lang.Thread.run(Thread.java:619) 20:01:44,803 ERROR [STDERR] Caused by: java.lang.ClassCastException: $Proxy85 cannot be cast to org.omg.CORBA.Object 20:01:44,804 ERROR [STDERR] at com.sun.corba.se.impl.javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:212) The code to get the session bean handler: Properties env = new Properties( ); env.put(Context.SECURITY_PRINCIPAL, "guest"); env.put(Context.SECURITY_CREDENTIALS, "guest"); env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.security.jndi.JndiLoginInitialContextFactory"); env.put(Context.PROVIDER_URL, "jnp://localhost:1099"); Context jndi = new InitialContext(env); Object ref = jndi.lookup("MyBean/remote"); instance = (MyBeanRemote) PortableRemoteObject.narrow(ref, MyBeanRemote.class); I can get "ref" from Context, just get error when narrow it. And with the same code deployed to tomcat, it works fine. I wonder whether anyone has met with this problem or can see some error in my code. Thanks a lot in advance!
