What you want is to use XSP for your output.  Have your servlet use a RequestDispatcher to
pass your servlet's XML object (either a DOM object or a String that you can read in) and
then pass that object on to your XSP page using something like this (i'm assuming you have
a DOM document or node but you can use a similar process to import a valid XML string I believe)


// node is an org.w3c.dom.Node

request.setAttribute("xmlnode", node);

RequestDispatcher rd = request.getRequestDispatcher("/yourxsppage.xml");

rd.forward(request, response);



then in you XSP you'd have something like:


<<xsp:logic>

	Node node = (Node) 	

	request.getAttribute("xmlnode");

	xspCurrentNode.appendChild(document.importNode(node, true));

<</xsp:logic>
