Two of the Same Netbeans Projects on One Server

Question

We only have one java server to work on (not counting local) for our dev and test environments. We want to be able to run a dev and a test version simultaneously however, so to solve that I've created two different projects, one for dev and the other for test. Otherwise, even if I change the project properties or rename the war file, the glassfish server recognizes it as the same project we already deployed and undeploys the previous version. Is there a way around this? I know the best thing to do is to have a separate java server, but that isn't possible right now.
