[jdom-interest] JDOM Closing my Servlet OutputStream

Tue Feb 20 02:10:37 PST 2001

Hi.

I'm new to JDOM and new to XML so I might be missing something obvious
here.

Whenever I use the DOM/SAX parser withing my Servlet doPost or doGet
methods, the ServletOutputStream seems to get trashed. For example I use
the code below:

public void doPost(HttpServletRequest req,HttpServletResponse res){
        DOMBuilder b = new DOMBuilder();
        // Create the document
        Document doc = b.build(req.getInputStream());
        Element node = doc.getRootElement();

        String bc = node.getChild("Request")
                          .getChild("PunchOutSetupRequest")
                          .getChild("BuyerCookie").getTextTrim();

        res.setContentType("text/plain");
        PrintWriter out = res.getWriter();
	 out.println("<html>Hello!</HTML>
	 out.flush();

etc...

Nothing gets out of the ServletOutputStream.  However if I remove the line
:

        Document doc = b.build(req.getInputStream());

Everything works just fine! So clearly something is going wrong with the
"build"....or maybe my mind:)

I have tried getting the printwriter before calling "build" but to no
avail.  I know the parser if working correctly since the Element text
returned is perfect.  If I send my output to the servlet log, the output
is fine. I just can't get anything out of the ServletOutputStream. I used
checkError() and it returns false and the stream is open.   I ran exactly
the same code against an xml file in a standard java class (not a servlet)
and it also works fine.

I'm using JDOM-b-6 and tested in Linux and W2K. I also have Jason and
Craig's Java-XML book but no clues there either.

Help!

Thanx

Chris

PS 
Jason since your Servlet Programming book is so fantastic, why not a nice
XML-Servlet book?
