Problem in deploying BMP based web application
Hi friends,
I am a new bea in JBoss field. I have deployed web applications in Sun Application Server 8.1 using NetBeans 4.1. Now, I am trying to deploy my J2EE applications in JBoss using JBoss 4.0 (latest) with JBoss(1.5.1GA) - Eclipse(3.1.1). First, I want to test a simple Database Application with a single BMP Bean and a single JSP which calls the BMP and shows data.
The EJB file:

I have not used any CMP code then why is this error? Please help me out, why is it happening, if you need any other file to see, tell me. But give me some clue. Please...
Thanx in advance
