XFire

I struggled with the sample web service provided with the XFire distribution.  The problem was that I placed the XFire services configuration XML in the WAR's META-INF directory instead of within classes/META-INF.  Incidentally, I discovered that in a servlet context getClass().getClassLoader().getResource() does not search the root context directory for resources -- it only searches the classes and lib subdirectories.  To get a resource from the root, you must use getServletContext().getResource().  After this short detour, the XFire service worked.

I was unable to get the XFire test framework run the service.  It throws a null pointer exception:
