[JNDI/Naming/Network] - Re: PortableRemoteObject.narrow() returns null
by info＠connext.co.za
Good Day,
Does anyone know how to fix this problem of the PortableRemoteObject.narrow() from returning null when using the Corba IIOP transport?
I have commented out the CorbaTransactionService mbean from the iiop-service.xml but still it does not work.
Hashtable<String, String> env = new Hashtable<String, String>();
env.put("java.naming.factory.initial", "com.sun.jndi.cosnaming.CNCtxFactory");
env.put(Context.PROVIDER_URL, "corbaloc::marka:3528/JBoss/Naming/root");
InitialContext context = new InitialContext(env);
Object ref = context.lookup("ejb/Test");
TestHome home = (TestHome) PortableRemoteObject.narrow(ref, TestHome.class);
System.out.println(home);
I am using 4.0.4 GA and the all server configuration.

As a side note, if anyone knows how to get Kerberos, GSS and CSIv2 working in the JBoss/IIOP.
