Question

Using Spring-JMS it is possible to receive messages within an external transaction context via the DefaultMessageListenerContainer.

However the only documented way to write a message is via JmsTemplate.send(…) and I can’t see how this can be coerced to use a given TransactionManager.

Can anyone point me in the right direction?

More info: Ensuring a transaction manager is available (WebSphereUowTransactionManager), using JmsTemplate.write against an Oracle AQjmsFactory.getQueueConnectionFactory(dataSource) results in:

So whilst I have no reason to doubt the advise below, I am not able to test it as I can’t figure out how to get AQ JMS to not attempt a commit. Will update as I learn more.

Answer 1

My understanding is that JMS producers are inherently transacted via JTA. By sending a message via JMS MessageProducer, the thread-local JTA transaction is used (if one is present).

This is hinting at by the Spring manual (section 21.2.5):

JmsTemplate can also be used with the JtaTransactionManager and an XA-capable JMS ConnectionFactory for performing distributed transactions. Note that this requires the use of a JTA transaction manager as well as a properly XA-configured ConnectionFactory.

This is also suggested by JmsAccessor.setSessionTransacted (the superclass of JmsTemplate) (javadoc):

Set the transaction mode that is used when creating a JMS Session. Default is “false”.
Note that within a JTA transaction, the parameters passed to create(Queue/Topic)Session(boolean transacted, int acknowledgeMode) method are not taken into account. Depending on the J2EE transaction context, the container makes its own decisions on these values. Analogously, these parameters are not taken into account within a locally managed transaction either, since the accessor operates on an existing JMS Session in this case.

Setting this flag to “true” will use a short local JMS transaction when running outside of a managed transaction, and a synchronized local JMS transaction in case of a managed transaction (other than an XA transaction) being present. The latter has the effect of a local JMS transaction being managed alongside the main transaction (which might be a native JDBC transaction), with the JMS transaction committing right after the main transaction.

So by start a JTA transaction (i.e. by using Spring’s transaction API with JtaTransactionManager) and calling JmsTemplate.send(...), you will be sending the message bound to that transaction.
