      Hi guys,

      I'm trying to make my first EJB work. I have no problems to deploy the ear file, and I'm able to put my web application working. But when I try to make my EJB work, it gets the following error:

      18:43:04,902 INFO [STDOUT] java.lang.ClassCastException
18:43:04,903 INFO [STDOUT] at com.sun.corba.se.impl.javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:229)

      My configuration files are the following:

      And the way I'm trying to get the home interface is: 
      Context initial = new InitialContext();
 Object objRef = initial.lookup("Organism");
 objRef = PortableRemoteObject.narrow(objRef, OrganismHome.class);
 OrganismHome home = (OrganismHome) objRef;
 organismController = home.create();



      Someone have some idea of why this is happening? I appreciate any help.
      I'm using JBoss 4.0.2.

      Thanks,
      Alexandre
