那位能两个简单的jsp页面，一个是发送一个接收

a页面要用HttpURLConnection对象用数据流的形式post一个字符串变量到b页面
b页面接收这个变量，并显示出来

呵呵,没必要啊??为什么要写页面呢??你如果是要测试的话,就自己写一个serverSocket就是了.然后用HttpUrlConnection来连,并write些东西,你再输出出来就是了?
URL url = null;
            HttpURLConnection connection = null;

            int responseCode = 0;
            String responseMessage = "";            url = new URL("127.0.0.1:端口号");
            connection = (HttpURLConnection)url.openConnection();
            connection.setRequestMethod("POST");
            connection.setRequestProperty("Content-Type","对应的类型");
            connection.setRequestProperty("Content-Length",Integer.toString(str.getBytes().length) );
            OutputStream out1=connection.getOutputStream();
            String str=new String("aaaaaaaabbbbbb");
            out1.write(str.getBytes());
            out1.flush();
ServerSocket s = new ServerSocket(端口号);
Socket incoming = s.accept( );
      in = new DataInputStream(incoming.getInputStream());
      out = new DataOutputStream(incoming.getOutputStream());
      String response;
           out.writeBytes(response);
      out.flush();
      out.close();
      in.close();
      incoming.close();
用HttpURLConnection发送post请求并获取目标内容，例子如下：
<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%>
<%@page import="java.net.URL"%>
<%@page import="java.net.HttpURLConnection"%>
<%@page import="java.io.DataInputStream"%>

httpurlconnection.getInputStream());
int ch;
while ((ch = inStream.read()) >= 0) {
System.out.print((char) ch);
}
} catch (Exception e) {
e.printStackTrace();
} finally {
if (httpurlconnection != null)
httpurlconnection.disconnect();
}

</body>
</html>testurlto.jsp内容如下<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

    <%=request.getParameter("username") %>

控制台打印的结果如下：
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <title>testto</title>
<meta http-equiv="pragma" content="no-cache">

<meta http-equiv="description" content="This is my page">
  </head>
  <body>
    user name is : <br>
    aaaaaa
  </body>
</html>
不是两个页面吗？怎么在控制台打印，a一个表单提交，过去之后用javaBean把结果在b中显示出来
为什么用javabean得出是歌String对象，直接在页面中输出就是了。
