高分求取用servlet发送和接受xml的例子！高手帮忙

Question

//package xml;
//创建一个xml已经可以了，问题就是怎么样发送这个xml。我编译通过了，但没有测试，估计有问题//主要问题一个是创建了xml后，返回一个document，怎么把它付给outputStream，然后发出去。
//还有resin是不是和tomcat一样，我知道在tomcat下配置Servlet，resin是不是一样？
//谢谢!!!

发送直接将XML post(get)给sevelet
  private String perform(String strAction, String strContent) throws Exception {
    URL url = new URL(strHostIP + strAction);
    System.out.println(strHostIP + strAction);
    HttpURLConnection con = (HttpURLConnection) url.openConnection();    con.setRequestMethod("POST");
    con.setDoOutput(true);
    con.setDoInput(true);    con.setRequestProperty("Content-Type", "text/xml");
    con.setRequestProperty("Accept", "text/xml");
    con.setRequestProperty("Connection", "close");    con.connect();    OutputStream os = con.getOutputStream();//    strContent = URLEncoder.encode(strContent, "GB2312");    byte[] b = strContent.getBytes("GBK");
    DataOutputStream dos = new DataOutputStream(os);
    dos.write(b);
    dos.flush();
    os.close();    InputStream is = con.getInputStream();
    String OutXMLStr = "";
    try {
      Util util =new Util();
      OutXMLStr =util.ReadInputStream(is);
    }
    catch (Exception e) {
    }    is.close();
    con.disconnect();
    System.out.println(OutXMLStr) ;
    return OutXMLStr;  }
