Re: [Springframework-developer] Bug in suspend/resume of rolled back transaction wih JOTM?

[Juergen H. <ju...@in...>]

Hi Andy,

I do not expect this behavior to change between different Spring versions.
The problem rather lies in the semantics of JOTM's
"TransactionManager.resume()" operation, which does seem to throw an
exception if the transaction to resume has already been marked for rollback.
Unfortunately, the JTA spec is not clear on how that operation should behave
in such a case; as a consequence, JTA providers differ in that respect.

As Thomas says, we know that issue from WebLogic, where the JTA
"TransactionManager.resume()" operation has the same semantics. WebLogic
provides a separate "forceResume()" operation (on its extended
TransactionManager interface) that will also resume a transaction that has
already been marked for rollback.

We simply provide a special WebLogicJtaTransactionManager now (a subclass of
our standard JtaTransactionManager), calling WebLogic's "forceResume()" and
also providing a couple of WebLogic-specific extensions. This works nicely
on both WebLogic 8.1+ and 7.0 now. I guess we will have to provide such a
special JtaTransactionManager for JOTM as well then.

However, it's not clear to me what such a special JotmJtaTransactionManager
would have to do to enforce a resume. There doesn't seem to be a
"forceResume"-style method anywhere in the JOTM API. It might be worthwhile
to check out Jonas's usage of JOTM: The Jonas EJB container essentially has
the same requirement, needing to enforce a resume of a transaction. I would
appreciate any help in finding out how to achieve this.

I should note that I've just tested this against Spring 1.2.5, which does
not change the result in any way.
