My QA department desires to have multiple versions of the application running on a single machine simultaneously so that they can do behaviour comparisons by simply re-directing traffic from one URL to another. Is this doable?

I know that I would need to
+ Change the name of the .ear file
+ Change the URI mappings for each of the .ear files so that they will be distinct

How is this going to work with EJB's? Is an EJB scoped by application (i.e. .ear file) or will I have to do something with the deployment descriptors?

What else do I need to know about having multiple versions running at the same time on the same server?
