When I'm running outside the app server Properties p = new Properties(); p.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.cosnaming.CNCtxFactory"); p.put("java.naming.corba.orb", myORB.orb()); p.put(Context.PROVIDER_URL, "corbaloc::localhost:3528/JBoss/Naming/root"); seems to be the way to go since ORBInitialContextFactory is not available. Inside the app server ORBInitialContextFactory does the right thing. Now if we can just sort out the TxServerInterceptor hardcoding, pluggable JTS integration may actually work.
