You java.library.path is not set correctly. As it is currently set, it will pick up ocijdbc10.dll but none of the DLLs on which it depends. Please read my previous reply again. If you do not pass java.library.path to JBoss AS, it too will use PATH. You will have to edit run.bat because that is where java.library.path is being set (that is because it tries to see if JBoss Native is installed).
