Re: [Springframework-developer] Stale JTA transaction still attached to a tread

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

Hi Dave,

That's indeed odd, in particular as Spring does not explicitly associate JTA
transactions with the current thread (of course the JTA provider itself will
use ThreadLocals underneath).

The only thing that could be bound to the thread by Spring within a JTA
transaction is a transactional resource, such as a JDBC Connection or a
Hibernate Session. Such resources should _always_ get removed from the
thread by Spring's corresponding synchronization classes, though: So if such
a resource would be the root cause, this would mean some bug in Spring's
resource cleanup code.

If you can track down any details, I'm gonna address this immediately (even
during the weekend). It would be great to clarify this before the upcoming
Spring 1.2.2 release...

Subject: [Springframework-developer] Stale JTA transaction still
attached to a tread


Hi Juergen,

Using Spring 1.2.1 with JtaTransactionManager with WebLogic 6.1. A
review of my logs showed a large number of JTA timeouts. The odd thing
is that the timeouts seem all to be occurring on the same thread. What
WebLogic reports as the transaction ID is always the same.

It appears to me that there is stale Spring JTA transaction attached to
this particular thread. Each time WebLogic releases this thread to a
request, and attempts to run some SQL (via Spring), it gets a JTA
timeout with the same transaction ID.

I'm about to restart our server, and I expect this to clear up the
problem. However, this is a pretty serious problem. I am going to go
back through the logs and attempt to locate the root error for this thread.

Thanks for your help,
Dave
