Service Activator & Transaction

Java Developer’s Journal

We process about 300 messages / second in our application. The Service Activator pattern has been very helpful to fork off and distribute processing of messages. We fork off messages to a JMS queue for processing. In some cases, the forked off messages need to run inside the same transaction of the caller and JMS helps us achieve this.
