Using different ILs on JMS with JBOSS 3.2.3

[bygos]

Hello.
I have JBOSS 3.2.3 installed. I use default deploy and my aplication uses JMS to heartbeat communication.
In jms directory there are 5 different il configuration file. All are deployed, and my application uses OIL. When I delete oil-service.xml jboss starts with exception and jms is not deployed.
How can I configure JBoss to use UIL2 ??

In your client application use: context.lookup("UIL2ConnectionFactory")
