I omit the transform.  I can transform the xml from the command line
without problem. When I put the two together this is the stack trace.

The problem is not in Cocoon but in Xalan, see below:

I appreciate that this error isn't much more helpful, but at least it gives you another place to look and also gives me a clue that the problem is in the XSL.

Have you tested it from the command line using Xalan or some other XSLT processor. Perhaps it was a different version of Xalan?

These are all guesses in the hope that they may give you inspiration, I can't be any more direct help I'm afraid.
