So you have XML posted to your servlet/JSP and you would like in turn
to post it back to another URL on the same server; is that it? In Java
you should be able to do that doing a forward with the servlet API.
Maybe I am asking too many questions :), but I am wondering why you
would need to do that, and if there is another way to do it within
Orbeon that wouldn't require you to write Java code.

So it seems you are using separate deployment (as documented on
http://www.orbeon.com/ops/doc/reference-xforms-java). Is that right?
If you are, HTTP requests from the browser are always handled by your
own servlet. If you have an XML document that you want to "pass to
XFoms", you can "write it" inside an <xforms:instance> ... your XML
here ... </xforms:instance>. Or am I misunderstanding your setup?

Thanks this did the trick.

The one catch is that the XML returned by the xforms has the xmlns="" removed from it. It also has <?xml version="1.0" encoding="UTF-8"?> added to the beginning. In order to make the get the XML to flow from page to page I need to remove the XML declaration and add the xmlns="" back in.

Thanks,
Dustin

If that is the problem, my favorite recommendation will be not to use
default namespaces to avoid this type of problems :).
