Marco,
The following snippet of code from a servlet may help. It
produces output.
Tom
public final class Transform extends HttpServlet {
private static DocumentCache cache = new DocumentCache(32);
public void doPost(HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
response.setContentType("text/html");
PrintWriter out = response.getWriter();
String className = request.getParameter("class");
String documentURI = request.getParameter("source");
String stylepath = getServletContext().getRealPath(className);
String xmlpath = "file:" + getServletContext().getRealPath(documentURI);
translet.setDOMCache(cache);
DOMImpl dom = cache.retrieveDocument(xmlpath, 0, translet);
DefaultSAXOutputHandler saxHandler =
new DefaultSAXOutputHandler(out);
translet.transform(dom, new TextOutput(saxHandler));
}
}
