A session bean class must not have a superclass that is itself a session bean class.

[Deepak Jain]

EJB Core Specification 4.6.2:
A session bean class must not have a superclass that is itself a session bean class.

I tested

@Stateless
public class PlaceBidBean extends ParentPOJO implements PlaceBidRemote {
 
public Bid addBid(Bid bid) {
System.out.println("Adding bid. bidder ID=" + bid.getBidderId()
+ ",item id=" + bid.getItemId() + " , bid amount="
+ bid.getBidPrice());
return bid;
}
}
 
package com.ejb3inaction.actionbazaar.buslogic;
 
import javax.ejb.Stateless;
 
@Stateless
public class ParentPOJO {
 
}

Result:
Works fine:
23:37:32,312 INFO [STDOUT] Adding bid. bidder ID=20091297,item id=22 , bid amount=200.0
What is the specification trying to convey?

Can someone please take time and respond this question.

Deepak,

Sorry for the delayed response...I have been on vacation.

The implemention you are using appears to be non-compliant.

Best regards,

This is third time in a row now.
Looks like one must not use jboss-4.2.3.GA.
The code was deployed with jboss-4.2.3.GA application server.
Please suggest a better application server which is completely compliant with ejb 3.0 specification.
