Bad envelope tag?

Hi all,

I am having some trouble integrating my XForms application with another web service.
Basically I am just calling a web service (that I have written myself) using a delegator processor.

I receive the call on the server side, set the content type for the response, and then write my XML
to the writer of the response. Like this:

        response.setContentType("application/xml");
        final PrintWriter out = response.getWriter();
        out.println("<evaluation>"); // Write my own XML here
        ...;

But then I get a SAXException "Bad envelope tag" when receiving the response. See below.
Obviously it seems that the delegation processor anticipates a SOAP envelope here.

But how do I continue from here? Do I really need to build a SOAP envelope? How do I do that in the simplest way?
Is there any other way? Can I configure the delegation processor to accept "raw" XML? I am just interested in passing
my XML to the client (ie my XForms app) in the simplest way possible. This is only going to be a simple prototype so
I don't want to go through a lot of hassle to make things production like.

RE: Bad envelope tag?

Message

Hi Patrik

How about implementing your service as a REST service?

You could then either

a) use the oxf:url-generator processor to get the data (passing any data as url parameters); or

b) use the oxf:xforms-submission processor, which means you could POST data to your URL - see http://www.orbeon.com/ops/doc/processors-submission
