RE: [Springframework-developer] PROPAGATION_REQUIRES_NEW and JTA

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

Transaction suspension should work with all of Spring's local transaction
managers too, including HibernateTransactionManager. It's even simpler than
in the JTA case: no need for special server-specific setup.

Subject: [Springframework-developer] PROPAGATION_REQUIRES_NEW and JTA



Hi Folks,

I'm wondering if it's possible to use PROPAGATION_REQUIRES_NEW *without*
using JTA.  I'm trying to use PROPAGATION_REQUIRES_NEW with the
following simple setup (using spring-framework-1.1):

HibernateTransactionManager whose sessionFactory is
a LocalSessionFactoryBean, and the sessionFactory
dataSource is a JDBC DriverManagerDataSource.

This isn't yielding the results I want yet.
I don't get any exceptions or obvious error
output, but I don't get the transactional behavior I expect either.
I'll need to do further work to diagnose, but first I
just want to make sure that such a configuration is intended to work.

Based on this post from Colin Sampaleanu, I suspect that JTA
may be required:

----
REQUIRES_NEW actually just suspends the current transaction, and then
 starts a new, unrelated transaction transaction to run the contained
 code in. If you commit the inner, new transaction, then rollback the
 outer, the inner transaciton will still be committed, as they are
 unrelated. This should work properly inside any JTA environment (as long
 as spring can get at the jta transaction manager) and the model is also
 essentially the same as the requires new support in the EJB spec.
----

Thanks for listening,
Jim Engquist
