Philippe,
OK. I set the trace levels you suggested and that identified the problem. The
transaction within which the compound entity bean is loaded (and all its
aggregated beans) was timing out. I was already trying to prevent this happening
by performing the load within a client-demarcated transaction with a long
timeout. But it looks like the timeout set on the client-demarcated transaction
is not having any effect. When I set a long timeout in jonas.tm.timeout, the
compound bean loads fine.
So there would be seem to be at least these possibilities:
a) I don't understand EJB transactions properly.
b) client-demarcated transactions are not working properly with 2.2.4.
c) the value in jonas.tm.timeout is overriding the timeout set on the
client-demaracted transaction.
It would be nice to be able to set a long timeout from the client, and use a
shorter value for jonas.tm.timeout. I didn't have any problems like this in
2.1.1, which makes me suspect there's a problem with 2.2.4.
I attach the trace as a .txt file. If you look near the top you'll see
"TransactionImpl.timeoutExpired(Object arg)".
Regards,
Joe
