Reentrant method call detected

milasx Feb 24, 2003 6:38 AM

I am using the JDBCOptimisticLock with
<optimistic-locking>
<modified-strategy/>
</optimistic-locking>
but gets lots of
javax.ejb.EJBException: Reentrant method call detected: MDSKeyVector
on my Entity EJB
Any idea on how to have parallel thread execution on this? Also note that I am currently only reading from the bean?

Thanks

Simone

Are you sure the cause is JDBCOptimisticLock?
If you use the default container configuration, do you see the same exception?

Hi Alex,
If I use the default QueuedPessimisticEJBLock I do not get the same error.
I do have a request per second or more to a Finder Method and if I use the QueuedPessimisticEJBLock all my request are serialized :)

I am using reentrant="false"

Thanks

If it works stably with pessimistic lock, then it's a bug in optimistic lock. It would be great, if you could provide a testcase and submit a bug report.

Thank you very much.
