Java EE (Java Enterprise Edition) General Discussion

Hi,

I am trying to create a simple j2ee application using weblogic 8.1 on XP with Oracle 9. I am trying to connect to an EJB using an java client. I will appreciate any help with this. The exception and code are as follows:
Exception:

bleRemoteObject.java:293)

public class Client_41{

try{

Class c = CabinHomeRemote.class;
System.out.println("Looking-up EJB Class \"Cabin\"...");
//System.out.println(ctx.lookup("CabinHomeRemote"));
Object obj = ctx.lookup("CabinHomeRemote");
System.out.println("Porting the CabinHomeRemote");
System.out.println(PortableRemoteObject.narrow(ctx.lookup("CabinHomeRemote"), c));
CabinHomeRemote home = (CabinHomeRemote) PortableRemoteObject.narrow(obj, CabinHomeRemote.class);
CabinRemote cabin_1 = home.create();
Integer id = cabin_1.getId();
cabin_1.setDeckLevel(1);
cabin_1.setShipId(1);
cabin_1.setBedCount(3);

CabinRemote cabin_2 = home.findByPrimaryKey(id);
System.out.println(cabin_2.getName());
System.out.println(cabin_2.getDeckLevel());
System.out.println(cabin_2.getShipId());
System.out.println(cabin_2.getBedCount());


}catch(Exception e){
e.printStackTrace();
}
