new to EJB

I have developed a simple eitity EJB (EJB 2.1) using jdeveloper and OC4J as embedded server. When I try to lookup home interface using a simple java client, I am getting javax.naming.NameNotFoundException: Employees not found. What might be wrong?

I have put the entries correctly in ejb-jar.xml. I don't think that is the problem. Here is the ejb-jar.xml file.

<?xml version = '1.0' encoding = 'windows-1252'?>
