Scenario 2: Setting up a JMS local transaction
This scenario applies only to a Talend solution with ESB.
In this scenario, a local transaction with three steps is performed to send, test and
consume a JMS message:
-
The first Route is used to send a “hello
world!” message to feed the queue.hello JMS queue. -
The second Route is used to test the received JMS message. This message is
redelivered six times to the queue.hello
queue and is then moved to the Dead Letter
JMS queue. The Route is programmed to throw an exception every time an exchange
is processed by the Route. -
The last Route is used to consume the “hello
world!” message from the Dead
Letter JMS queue.
In this use case, we use the local ActiveMQ server to handle messages between
different Routes. The ActiveMQ server need to be started before executing the Routes.
For more information on installing and launching ActiveMQ server, see the Apache Web
site http://activemq.apache.org/index.html.
