Looking up an EJB 2.1 (deployed on Weblogic AS) from JBoss AS 5.1.0.GA gives this message: unable to build ORBInitializer from *class* *true*: Ignoring The lookup code is: EJBHome ejbHome;         properties = new Properties();         properties.put("java.naming.factory.initial", "weblogic.jndi.WLInitialContextFactory");         properties.put("java.naming.provider.url", providerUrl);         properties.put("weblogic.jndi.requestTimeout", Long.valueOf(jndiRequestTimeout));         if(user != null)         {             properties.put("java.naming.security.principal", user);             properties.put("java.naming.security.credentials", password != null ? ((Object) (password)) : "");         }         Context jndiContext;                     try {                               jndiContext = new InitialContext(properties);                               yacasHome = (YacasHome)jndiContext.lookup(jndiName);                     } catch (NamingException e) {                               ...                     }         try {                               this.ejb = ejbHome.create();                     } catch (Exception e) { ...                     } and initialization fails. It seems that while initializing ORB it cannot find an ORBInitializer implementation.
