Failed to create "ejb/collaxa/system/FinderBean" bean; exception reported i

Question

I am unable to invoke BPEL service from an OA framework page. I am getting following error when I am trying to Invoke.
oracle.apps.fnd.framework.OAException: java.lang.Exception: Failed to create "ejb/collaxa/system/DeliveryBean" bean; exception reported is: "java.lang.NullPointerException: domain was null

Code I am using to invoke is:
          Hashtable jndi = null;
          jndi = new Hashtable();
          jndi.put(Context.PROVIDER_URL, "ormi://142.176.225.111:23791/orabpel");
          jndi.put(Context.INITIAL_CONTEXT_FACTORY, "com.evermind.server.rmi.RMIInitialContextFactory");
          jndi.put(Context.SECURITY_PRINCIPAL, "oc4jadmin");
          jndi.put(Context.SECURITY_CREDENTIALS, "welcome1");
          Locator locator = new Locator("default", "welcome1", jndi);
          IDeliveryService deliveryService = (IDeliveryService)locator.lookupService(IDeliveryService.SERVICE_NAME );
          //System.out.println("4444");
          String xml ="<FirstTestBPELProcessProcessRequest xmlns=\"http://xmlns.oracle.com/FirstTestBPELProcess\"><input>123456789</input></FirstTestBPELProcessProcessRequest>";
          NormalizedMessage nm = new NormalizedMessage( );
          nm.addPart("payload", xml );
          NormalizedMessage res = deliveryService.request("FirstTestBPELProcess", "process", nm);
          Map payload = res.getPayload();
          Element elem = (Element)payload.get("payload");
This code works excellent when called from a stand alone java class but it is not working when it is called from an OA Page.
Can some one provide any pointer to the error.

Answer 1

I think that your problem is that the Context.PROVIDER_URL is wrong.
Here is a sample of url that we use here:
opmn:ormi://servername:6005:home/orabpel
where:
"servername" is (duh) the servername
"home" is the container that bpel is running
"6005" is the opmn port.
