Running two jboss servers on one box problems. plz help
Hi,
I've run into a wall configuring two jboss servers on one machine.
It's a linux environment with jdk1.4 having two installations of jboss 3.0.4.
All the port numbers have been changed on the second jboss instance.
Everything works as expected on the first instance I started but on the second jboss server things don't work out as expected.
All the base services seem to startup correctly.
Then during initialization in the web container,
when accessing a stateless session bean, I get a linkage error.
java.lang.LinkageError: loader constraints violated when linking javax/transaction/UserTransaction class

The application deployed on server A nd B is identical. The only difference exist in the ports and db used.
Can anybody shed some light on why this could happens only in the 2nd application?
I thought it might have something to do with that the webcontainer from server B loads something from server A. Is this possibly the reason?
What could I do to solve this?
Any suggestions would be greatly appreciated as I'm reaching close to despair.
