I have noticed that if you have some class files missing, the initialization fails with this exception. The way I debugged this was to (I use Jbuilder, although I suspect this will work with Eclipse as well) set an exception breakpoint and look at the trace file. It's probably a ClassNotFoundException (this is just a guess)- that's what it was for me. Putting the proper jar files in the class path fixed the problem for me Raghavan
