How can I call remote ejb through jsp?(null)

Answer 1

Trying the code:
          <%@ page import="si3.*,javax.ejb.*,javax.naming.*,java.util.*,java.rmi.RemoteException" %>
          <%
          int h=8;
          int w=8;
          Hashtable p = new Hashtable ();
          p.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory");
          p.put(Context.PROVIDER_URL,"t3://192.168.0.203:7001");
          Context ctx= new InitialContext(p);
          Object homeref = ctx.lookup("si3.test");
          addHome home = (addHome) PortableRemoteObject.narrow(homeref, addHome.class);
          add the_ejb = home.create();
          out.println(the_ejb.add(h,w));
          out.println("adf");
          the_ejb.remove();
          %>
