Problem-Writing datas to a Servlet thro' URLConnection class

Question

Hi,
Iam trying to post some string data to a servlet.
The servlet reads 2 parameters from url.And reads the xml string message thro post method.
So in the client program, I added those parameters to the URL directly like this,
"http://localhost/servlet/test?action1=value1&action2=value2" ,and created url object .
And using URLConnection iam trying to post the xml string.
But the servlet does not read the parameter values.Is my approach is correct?
client code:
package test;
import java.net.*;
import java.io.*;
import java.util.*;
public class Testxml{
public static void main(String ars[])
String XML="<?xml version='1.0'?><Test><msg>test message</msg></Test>";
String server="http://localhost/servlet/test";
String encodeString = URLEncoder.encode("action1") + "=" + URLEncoder.encode("something1")+"&"+URLEncoder.encode("action2") + "=" + URLEncoder.encode("something2");
try{
     URL u = new URL(server+"?"+encodeString);
     URLConnection uc = u.openConnection();
     uc.setDoOutput(true);
     uc.setUseCaches(false);
     uc.setRequestProperty("Content-type", "application/x-www-form-urlencoded");
     OutputStream out = uc.getOutputStream();
     PrintWriter wout = new PrintWriter(out);
     wout.write(alertXML);
     wout.flush();
     wout.close();
     System.out.println("finished");
     catch(Exception e) {
     System.out.println(e);
Servlet code:
package test;
import java.io.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class test extends HttpServlet {
public void doGet(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException {
     performTask(req, res);
public void doPost(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException {
     performTask(req, res);
public void performTask(HttpServletRequest request, HttpServletResponse response) {
     try{
String action1=request.getParameter("action1");
String action2=request.getParameter("action2");
if(action1.equals("something1") && action1.equals("something2") )
     ServletInputStream in = request.getInputStream();
     byte[] buffer = new byte[1024];
     String xmlMsg = "";
     int len = in.read(buffer,0,buffer.length);
     if(len>0)
     while (len > 0 ){
               xmlMsg += new String(buffer,0,len);
               len = in.read(buffer);
     System.out.println("xml : "+xmlMsg);
This is not working.Even,it does not invoke servlet.Is this approach is correct?.
Thanx,
Rahul.
