[jdom-interest] xmlOutputter question

[Rick Avlonitis]

When I call xmlOutputter.output(docForPosting, http.getOutputStream()), this
fails to update the data  but I get: (Response Code: 200, Response Message:
OK).
But when I write the docForPosting to a file and then create a new document
from the parsed file, I can successfully update the data (Response Code:
200, Response Message: OK).

Why can I not put data successfully on the server with
xmlOutputter.output(docForPosting, http.getOutputStream())?

Your help will be appreciated.  My code is below:
