Hi,
I am using version 2.1.1 of JOnAS. I can't use
session bean that references an entity bean
because I get a NullPointerException.
Here is a simple example to illustrate my problem:
I want to design a bean that implements
multiple interfaces. Most of the clients
use methods of interface A and a specific service
uses methods of interface B. All the methods of
A are included in B.
Moreover my bean has persistant fields.
My solution was to design an entity bean whose
remote interface inherit from B and to design
a session bean whose remote interface inherit
from A.
My session bean has a reference on the entity
bean's EJBObject. and the create method take the
entity bean's EJBObject.
For each method m of the session bean, we call
the same method on the entity bean's EJBObject.
In a client, I retrieve a reference on the entity bean's
EJBObject (with a finder method) then I construct my
session bean. When I invoke a method an the session
bean, a NullPointerException occures ...
I have found that the reference of the entity bean's EJBObject
is null but why?
Thanks for any suggestion,
Audrey
