Ladies and Gentlemen, I see a large number of stack traces on my service indicating that incorrect username/passwords were passed (the correct ones are SC06 and SC06 respectively). I also see some indications that unrecognized soap headers are being used as well (which supports my theory that the reference parameters aren't getting passed correctly). The ClassCastException is indicative of this as well. For reasons that are unfortunate (and fixed in the next version of Genesis II), if you don't send me headers that I recognize as reference parameters, then I load a different class then normal for the resource, but your operation is target at something that needs the former type of resource, hence the class cast exception. Thus, if you can send me a copy of the soap messages you are sending me, I can further identify this problem. If you can't do that, then send me a Yahoo IM at mmm2a42 so I can set up the endpoint in extreme debugging mode to get a copy of your message. I'm at the OGSA F2F so I can't devote 100% of my time to this, but if you IM me ahead of time, I can interact with you and get the debugging turned on temporarily. -Mark -- Mark Morgan Research Scientist Department of Computer Science University of Virginia http://www.cs.virginia.edu mmm2a@virginia.edu (434) 982-2047
