Assuming you are running this on Weblogic:

Hashtable env = new Hashtable();
env.put(InitialContext.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
env.put(InitialContext.PROVIDER_URL, SERVER_ADDRESS);
InitialContext ctx = new InitialContext(env);
companyHome home = (companyHome) PortableRemoteObject.narrow( ctx.lookup("ejb/company"), companyHome.class );
companyRemote remote = home.create();
String companyName = remote.getCompanyName(); Source: CoolInterview.com
