// URL url = getServletContext().getResource("/WEB-INF/web.xml");
// JSP 中取得 /WEB-INF/web.xml
URL url = session.getServletContext().getResource("/WEB-INF/web.xml");
InputStream inputStream = url.openStream(); 
try {
 // read from inputStream
 BufferedReader br = new BufferedReader(new InputStreamReader(inputStream));
 String line = br.readLine();
 while(line != null) {
  out.println(line.replaceAll("<","&lt;").replaceAll(">","&gt;"));
  line = br.readLine();
