Could not invoke method getObjectInstance on object of type com.ibm.ws.naming.urlns.genericURLContextFactory error on JNDI lookup

Question

Do you know why I'm getting this exception ?

String url = "corbaloc:iiop:localhost:2809";
String initial = "com.ibm.websphere.naming.WsnInitialContextFactory";
String jndi = "ejblocal:my/ejb/PeriodoBO";

Hashtable<String, String> pdEnv = new Hashtable<String, String>();
pdEnv.put("java.naming.provider.url", url);
pdEnv.put("java.naming.factory.initial", initial);
Context initialContext = new InitialContext(pdEnv);

try{
    Object ejbHome = initialContext.lookup(jndi); // <-- here
    Object obj = PortableRemoteObject.narrow(ejbHome, PeriodoBO.class);
}catch(NamingException e){
    System.err.println(e.toString());
}

I'm sure that the JNDI is ok, I was struggling to get it (What's the default JNDI name of an EJB in Websphere Application Server 7 (WAS)?).

Could you help me please?

This is my run configuration :

UPDATE, I have just got the stack trace, I'm analyzing it :

Answer 1

ejblocal:my/ejb/PeriodoBO points to the local interface. Local interface cannot be accessed by the Java EE Application Client. You need the Remote interface.

Add @Remote with correct interface to your bean. Then during app initialization you will find in the SystemOut.log binding name to which the interface was bound in the JNDI. Then in initialContext.lookup(jndi); use that JNDI name.

Hope it helps
