Now the problem is occuring for changes to things other than the persistence.xml file. Now, changes to the classes results in the above error, which is solved by a restart of the server. What is causing this? What does "Wrong target" even mean? Please help, I'll waste an unreal amount of time in server restarts rather than actually learning JBoss if I don't solve this!
