a) Yes b) Yes Here is what happened. Earlier versions of JBoss Native included all of their DLLs in a 'native' directory. The run.bat file in JBoss AS 4.2.x looks for the 'native' directory and if it finds it adds it to the PATH. So the whole point is to match up the DLL locations in JBoss Native with the PATH location coded into run.bat. And you can do that either by copying the DLLs to native, or changing the run.bat to look for the DLLs elsewhere.
