rpa_rio,
I'm not sure if you have found an answer for your question, but hopefully I can
help. This took me a pretty minute to figure out. I use XDOCLET to generate
all the helper classes and setup XML. Of course, your mileage may vary.
The brief setup looks like:
I did the following for my setup which is similar:
