Error while trying to access BPEL process through java on localhost

Question

I have a service (CreditRatingService that comes along with install) running on the BPEL engine. Trying to invoke it through java. However, I get an exception. Below is more information. Appreciate any help.
My method
    public String invokeBpel()
      Map payload;
      Hashtable jndi = null;
      try
       String ssn ="1234";
       String xml = "<ssn xmlns=\"http://services.otn.com\">" + ssn + "</ssn>";
        Locator locator;
        locator = new Locator("default","welcome1",jndi);
         IDeliveryService deliveryService =
          (IDeliveryService)locator.lookupService(IDeliveryService.SERVICE_NAME );
          NormalizedMessage nm = new NormalizedMessage( );
          nm.addPart("payload", xml );
            NormalizedMessage res =null;
            try
             res = deliveryService.request("CreditRatingService","process", nm);
            catch(RemoteException oNameEx)
                System.out.println(oNameEx.getMessage());
            payload = res.getPayload();
            System.out.println( "BPELProcess CreditRatingService executed!<br>" );
            System.out.println( "Credit Rating is " + payload.get("payload") );
      catch (Exception e)
        System.out.println("This is the exception" + e);
        System.out.println(e.getStackTrace());
      finally
          return "toPage3"; 
    }//end method

Hashtable jndi = null;
try
String ssn ="1234";
String xml = "<ssn xmlns=\"http://services.otn.com\">" + ssn + "</ssn>";
Locator locator;
locator = new Locator("default","welcome1",jndi);
this implies to be in the same initial context then the bpel engine, whicuh you cannot be as long as you are not either part of the ejb code of orabpel or a child of it. and if you are you can use the Locator API without the jndi properties.
