hi, I have deployed a sample EJb(Helloworld) on Oracle8i(8.1.6) database and am enable to run it thorough the client. The example is provided by Oracle with their software. The problem I am facing is the Lookup failure and msg I am getting is following:=>C:\helloworld>java Client sess_iiop://tooshar:2481:FIRST /test/Tushar scott tiger
Inside main
Before Lookup

The exception makes it obvious that the object for which you are performing a lookup hasnt been deployed on the server OR it has been deployed and you are using the wrong name in the lookup.
