box) to my servlet.Iam using Tomcat server4.0 and  I

Below r my codes:-

Swing Interface(Iam pasting only action event of my
submit button):-
================
public URL u;
public URLConnection uc;
submit.addActionListener(new ActionListener()
 {
   public void actionPerformed(ActionEvent e)
      {
        String userid1;
        String password1;
        String Content;
        String
url="http://127.0.0.1:8080/examples/servlet/loginServlet";

        userid1 = userid.getText();
        password1 = password.getText();
        System.out.println(userid1);
        System.out.println(password1);
        Content= userid1 + password1;
      try{
        u = new URL(url+"?name=" +userid1 + "&path=" +
password1);
        uc =u.openConnection();
        uc.setDoOutput(true);
        uc.setDoInput(true);
        uc.setUseCaches(false);
        printout = new
DataOutputStream(uc.getOutputStream ());
        printout.writeBytes(Content);
        printout.flush();
        printout.close();
       }catch(Exception ex){System.out.println("Error
from actionPerformed :" + ex.getMessage());}
                    }
});

Servlet file:-
=============
import java.io.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class loginServlet extends HttpServlet
        {

          public void doGet(HttpServletRequest
req,HttpServletResponse res)
          throws ServletException,IOException
                {

                         res.setContentType("text/html");
                         PrintWriter out=res.getWriter();
                         String
str1=req.getParameter("name");
                         String
str2=req.getParameter("path");
                         /*DataInputStream dis;
                         dis = new
DataInputStream(req.getInputStream());

                         String str =
dis.readLine();*/
                         System.out.println(str1);
                         System.out.println(str2);
                }

        }
