Hello Jim,Hi Alex,
related entities must be in the same ejb-jar module.

JC> Hi,Hi,
I am implementing some beans in cmp2 (jboss304+tc406) for the first time and I am trying to solve a problem which has to do with one bean being able to see another bean, which is packaged into a seperate ejb jar file, at deployment time. Perhaps this question might better fall under the topic of j2ee packaging but here's my question anyway.
I have the following relationship hierarchy I am trying to emulate:
User 1:N Property 1:N Advert
Here is the error from the consol log:

Advert (ejb-jar.xml): no relationship definitions.
Note each bean is packaged in its own jar file. So it seems I would need to find a way to set up visibility of ejb jars correctly.
I'm not sure what the consequences would be of using different packaging so I have not been down that road.
I would apreciate it if anyone could give some feedback on this.

Thanks for the response! (I was beginning to climb the walls) Is this documented in the J2EE spec? I looked at it and didn't see any mention. (Could be the amount of time I've spent on this, though.)
