[jboss-user] [JCA/JBoss] - ActiveMQ JCA connector and Spring 2 application conflict in

[luciano61]

If I try to deploy the ActiveMQ JCA resource adapter (activemq-rar-4.1.0-incubator.rar) side by side with a Spring 2 war in JBoss 4.0.5 , I get the following error on server startup: 

ERROR

The problem is reproducible with any Spring 2 app (like the jpetstore sample of Spring 2.0.2 distribution), not only mine, to try yourself these are the steps:
1)Install a fresh Jboss (I tested 4.0.3 and 4.0.5) and verify it starts without problems
2)Stop JBoss
3)Put the activemq-rar-4.1.0-incubator.rar and jpetstore.war in the deploy JBoss dir
4)Start JBoss and you will see my stack trace 

The only workaround I found is to remove the Spring 2 jar from the ActiveMQ rar, but as I think is a classloader problem, there isn't a correct way of insulating JCA connector from apps?
I tryed also to put the activemq .rar  inside an .ear file as described here

but nothing changed.
