Norton,
Our problem from the previous thread that you refer to was that in our
ejbPassivate code we did not set our dataholder to null.
Ok - I think this is what your problem is:
If you are holding references to other ejbs, the you should set them to null
in ejbPassivate and re-obtain them in ejbActivate. This is because the
object instance that you get when the bean is re-activated may not be the
same instance that the bean was loaded into.
again - I say I think... if I'm wrong I hope someone will correct me and I'm
not misleading too many ppl.
cheers
