Does optimistic locking work with Blobs?

[palob]

Hello,
I have CMP entity bean which I tried use with optimistic locking. I've updated jbosscmp-jdbc.xml as manual states. Version number is used as strategy for optimistic locking.

But saving bean with blob column updated throws exception.

org.jboss.tm.JBossRollbackException: Unable to commit, tx=TransactionImpl:XidImp
l [FormatId=257, GlobalId=sonic//27, BranchQual=] status=STATUS_NO_TRANSACTION;
- nested throwable: (javax.ejb.EJBException: Store failed; CausedByException is:

null)

When updating of blob field is uncommented, everything works OK.
Can you tell me if JBoss 3.2.2RC2 supports blob columns for optimistic locking?
BTW, application works with pessimistic locking.

Thanks,
Pavol

I had the exact same problem. Thank you for posting this error as I would have spent a lot of time debugging this in my app.

It works for me in 3.2.4RC1. I think, it should also work in 3.2.3.
