I'm trying to use chunked encoding to transfer xml data to a custom XML-Rpc 
server.  This on W2k w/ Tomcat 4.0.1 final and JAXP 1.1.  Below is the 
exception, it works without fail as long as I don't use chunked encoding.  I'm 
simply passing the inputstream into the JAX parser.  I noticed that crimson and 
catalina both do a close.  I don't know which is correct but I know this works 
as long as I don't do chunked encoding.

    public void doPost(HttpServletRequest req, 
		       HttpServletResponse res)
	throws ServletException, IOException 
    {
	// Check to see if there is a header for
	// a particular encoding for the response.
	String encoding = req.getHeader("ResponseEncoding");
	if (encoding == null || encoding.equals(""))
	    res.setContentType("text/xml;charset=UTF-8");
	else
	    res.setContentType("text/xml;charset="+encoding);

	// Run Server Method the response will be written
	srv.run(new InputSource(req.getInputStream()),encoding,res.getWriter());
    }


Thanks,
Will
