Pass through the url value to the servlet , servlet how to set the return value , so that others call the url address to get ?

I pass through the url value to the servlet ,
url is :

http://localhost:8000/Serclet/test?name=qq&pwd=123

servlet Lane is written like this:

  public void doGet(HttpServletRequest request, HttpServletResponse response)
  			throws ServletException, IOException {
  
  		response.setContentType("text/html");
  		PrintWriter out = response.getWriter();
  		
  		String name=request.getParameter("name");
  		String pwd=request.getParameter("pwd");
  		
  		System.out.println("发送的内容："+name+"#"+pwd);
  		
  		request.getSession().setAttribute("name", name);
  		request.getSession().setAttribute("pwd", pwd);
  		
  		response.sendRedirect("MyJsp.jsp");
  		
  		out.flush();
  		out.close();
  	}
  
  

Now I want to get the servlet by calling the url return value , how does the servlet, how to write code that can only be obtained in the following return values ​​it ? Seek expert advice below:
I call the following code:

  public static void main(String[] args) {
  		
  		URL url=null;
  		BufferedReader budr=null;
  		try {
  			url=new URL("http://localhost:8000/Serclet/test?name=qq&pwd=123");
  			budr=new BufferedReader(new InputStreamReader(url.openStream()));
  			System.out.println("qqqqqq");
  			System.out.println(budr.readLine());
  		} catch (MalformedURLException e) {
  			// TODO Auto-generated catch block
  			e.printStackTrace();
  		} catch (IOException e) {
  			// TODO Auto-generated catch block
  			e.printStackTrace();
  		}
  	}
  
  

------ Solution ------------------------------------- -------
the budr contents all out to see them .
really have not seen anything like this to invoke the servlet
------ Solution - -------------------------------------------
doGet How to return value ah ?
------ Solution ---------------------------------------- ----
so you can do , servlet attached to the web environment , directly resolve an url, seemingly not right
------ Solution --------------- -----------------------------
amount you should only call this page something caught MyJsp.jsp ; session inside the value should not catch it I think
------ Solution -------------------------- ------------------
public void doGet (HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {

response.setContentType ("text / html");
PrintWriter out = response.getWriter ();

String name = request.getParameter ("name");
String pwd = request.getParameter ("pwd");


out.write ("xxxxxxxx");
out.flush ();
out.close ();
}

budr is to call the url address , and this is the url address pointing servlet. budr where only write so much. servlet, you can not pass values ​​to the jsp page do ? I am now thinking I only call this url via budr Can you get the servlet value. servlet inside how to write it ?

I am now going to ask how to write in a servlet url can only be obtained by calling the servlet value. As I entered directly in the browser http://localhost:8000/Serclet/test?name=qq&pwd=123, you can get a value.

session that how we can get the value of it ? I have seen http://ipyy.net/WS/UpdPwd.aspx?CorpID = * & Pwd = * & NewPwd = * this message interface , direct mass participation can be further page to get a return value. Url can also be obtained by calling the return value. I am now the url does not just tell him the same kind of interface do ? How do I write a servlet can as he did in the browser, the return value can be entered , the call can also get the return value?

MyJsp.jsp inside the session in which the value of the output to inputStream inside out and then grab did not know this right

url = new URL ("http://localhost:8000/Serclet/test?name=qq&pwd=123");
url where you have the name and pwd values ​​, the interception would not it ?

may be possible , do not put value on the request inside
directly PrintWriter output

PrintWriter how to write it ? I need to write jsp pages do ? If necessary , PrintWriter is written in the servlet or jsp pages in it ? PrintWriter output is how to write it ? Thank you advice !

url to access the servlet servlet reads inside , the same as ajax submit returns does not point to the page directly return text data ;
