WebSphere AS, ActiveMQ and XA Transaction

Hi there,

after a frustrating long time research on Google results from the "active mq xa webphsere" search, I decided to write a post about it. I lost several hours to realize that it is just about the minor details, as I couldn't find a text explaining the whole thing, I tried a bunch of different sets and it is finally working.

Here is what you need to do:

On WAS (WebSphere Application Server):

1. Go to "Resources -> JMS -> JMS Providers" (Menu on the left)
2. Pick up a scope (Cell, Node, Server)
3. Click on the "New" button
4. Set  the attributes as follows:
   • Name: ActiveMQ
   • <<Class path / Native library Path>> - If your application is deployed with "activemq" libs you don't need to worry about these attributes.
   • External initial context factory: org.apache.activemq.jndi.ActiveMQWASInitialContextFactory
   • External provider URL: tcp://localhost:61616
5. Click on the "Apply" button
6. On "Additional Properties" tab (at the right) click on "Custom properties" link
7. Add the following properties:
   (Remember: it is a 'key=value' pair property, the first 'text box' is the 'key', the second one is the 'value')
   • java.naming.connectionFactoryNames = QueueConnectionFactory
   • xa = true
8. Go to "Resources -> JMS -> Connection factories" (Menu on the left)
9. Pick up a scope (the same as you did on step 2)
10. Click on the "New"button
11. Set the attributes as follows:
    • Name: Queue Connection Factory
    • JNDI name: QueueConnectionFactory
    • External JNDI name: QueueConnectionFactory
    • Security settings -> Mapping-configuration alias: ClientCointainer
12. That is it! Done!
