I assume you're writing your own code and not using the testXSLT sample? If so, is that all there is to the error message, or is there more? You might also try debugging your code to see where the exception is being thrown.

I get an exception "Failed to process stylesheet!". How do I tell what is going wrong? Thanks Lyle
