I'm trying to build an MVC application using EJB to access a database. But I've met an unexpected problem: in my servlet (C-part of MVC) i want to use my EJB to get data through it. And that's why I must have EJB's interfaces imported into my servlet. Otherwise it won't compile. But then I'll get ClassCastException trying to do

  | InitialContext init = new InitialContext();
  | Object objref = init.lookup("TheNews");
  | NewsHome home = (NewsHome)PortableRemoteObject.narrow(objref, NewsHome.class);

Because interface NewsHome and objref are loaded with different ClassLoaders.

How should I pack my ear-file and how to organize access to EJB functions: from servlet(how?) or somewhere else?
