Problem While calling a session bean (J2EE)

Question

Hi!!
Please see my client-side code..where I am calling a session bean (J2EE Server)
It's correct or not?????
InitialContext ctx = new InitialContext();
Object objref = ctx.lookup("SecDbSecRoleJndi");
SecBusSecRoleHome home =(SecBusSecRoleHome)PortableRemoteObject.narrow(objref,SecBusSecRoleHome.class);
SecBusSecRoleRemote remote =(SecBusSecRoleRemote)PortableRemoteObject.narrow(home.create(),SecBusSecRoleRemote.class);
Here I am getting the error at 3rd line
java.lang.ClassCastException
at com.sun.corba.se.internal.javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:296)
at javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:137)
at TestServlet.init(TestServlet.java:22)
Please do the favor to me..reply me back.

Hello,
Hope you are bale to sole the problem by this time. Iam using the follwing code and its working fine for me. i'm using the weblogic application server.
<%@ page import="javax.naming.*, java.rmi.*, javax.ejb.*, java.util.*,java.rmi.server.*,java.net.*,javax.rmi.PortableRemoteObject,com.hmp.webcasting.services.ejb.*"%>
<%
try{             
Properties prop = new Properties();
prop.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
          System.out.println("Hello......3333333333Test");
          prop.put(Context.PROVIDER_URL, "t3://pani:7001");
          InitialContext ctx = new InitialContext(prop);
Object home = ctx.lookup("personMgr");
          KeywordsMgrHome roleHome = (KeywordsMgrHome) javax.rmi.PortableRemoteObject.narrow(home, KeywordsMgrHome.class);
          KeywordsMgr kmgr=roleHome.create();
          //KeywordsMgrHome roleHome = (KeywordsMgrHome) ctx.lookup("personMgr");;
          System.out.println(roleHome);
          System.out.println(kmgr);
          }catch(Exception e){
          e.printStackTrace();
          %>
Try using this.
Genrally calss cast exception occurs if you are using classes out of a shared library directory instead of within the webapp, or if you are somehow maintaining references to object instances created with the old class and trying to use them after the reload. So try to delete the old file files and deploy the bean once again . Hope this may help you. Anyway if you can give the full code i will check by deploying it.([email protected])
