Calling getEJBObject from SFSB instance

[gmyrek]

Hi,

I have a question to calling getEJBObject from stateful bean instance.

If I understand EJB 2.1 spec. correctly it is allowed to call getEJBObject from ejbCreate/Remove/Activate/Passivate. Calling this method is "disallowed in the session bean methods in which there is no session object identity established for the instance." and "disallowed if the session bean does not define a remote client view".

I have SFSB with remote interface and I get IllegalStateException exception when calling getEJBObject from ejbActivate and ejbPassiavate. I use JBoss 4.0.3 SP1.

Is this a spec. violation?

Thanx,
Marek.

Show the exception trace.

Show the exception trace.

This is a very simple SFSB. I tested SFSB cache, so I put debug statements into ejb/Create/Activate/Passivate/Remove callbacks.

It looks like AllowedOperationsAssociation assumes ejbPassivate is called on home ?

Below the stack trace.

Btw. would you plese explain why with SFSB cache when calling a business method on passivated bean a new bean instance is created, which is actually not used during method invocation.

Thanx,
Marek.
