[finde datei nicht (servlet, XSLT-transformation)]

Leider funktioniert das immer noch nicht das ist mein gesamter code den du hier abgebildet siehst.

public class neu extends HttpServlet {

public void init(ServletConfig config) throws ServletException
  {
    super.init(config);
  }

public void doGet (HttpServletRequest request,
                     HttpServletResponse response)
    throws ServletException, IOException, java.net.MalformedURLException
  {
    // The servlet returns HTML.
    response.setContentType("text/html; charset=UTF-8");
    // Output goes in the response stream.
    PrintWriter out = response.getWriter();
    try
    {
      TransformerFactory tFactory = TransformerFactory.newInstance();
      // Get the XML input document and the stylesheet.
      Source xmlSource = new StreamSource(new URL("file:/WEB-INF/menu.xml").openStream());
      Source xslSource = new StreamSource(new URL("file:menu2.xsl").openStream());
      // Generate the transformer.
      Transformer transformer = tFactory.newTransformer(xslSource);
      // Perform the transformation, sending the output to the response.
      transformer.transform(xmlSource, new StreamResult(out));
    }
    catch (Exception e)
    {
      out.write(e.getMessage());
      e.printStackTrace(out);
    }
    out.close();
  }

}
