Getting a request in a non English character

Question

Hi ,
In an attempt to solve a problem of getting a request in a non English character , i use the code , taken from O'Reilly's "Java Servlet programing" First edition:
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
public class MyServlet extends HttpServlet {
     public void doGet(HttpServletRequest req, HttpServletResponse res)
                                                                           throws ServletException, IOException {
          try {
                                                  //set encoding of request and responce
     req.setCharacterEncoding("Cp1255"); //for hebrew windows
     res.setCharacterEncoding("Cp1255");
     res.setContentType("Text/html; Cp1255");
     String value = req.getParameter("param");
                                                  // Now convert it from an array of bytes to an array of characters.
     // Here we bother to read only the first line.
                                                  BufferedReader reader = new BufferedReader(
     new InputStreamReader(new StringBufferInputStream(value), "Cp1255"));
                                                  String valueInUnicode = reader.readLine();
          }catch (Exception e) {
          e.printStackTrace();
this works fine , the only problem is that StringBufferInputStream is deprecated .
is there any other alternative for that ?
Thanks in advance

Hi Again ..
To get to the root of things , here is a servlet test and an http client test which demonstrates using the above patch and not using it :
The servlet :
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.io.StringBufferInputStream;
public class Hebrew2test extends HttpServlet {
     public void doGet(HttpServletRequest request, HttpServletResponse response)
     throws ServletException, IOException {
          request.setCharacterEncoding("Cp1255");
          response.setCharacterEncoding("Cp1255");
          response.setContentType("Text/html; Cp1255");
          PrintWriter out = response.getWriter();
          String name = request.getParameter("name");
          //print without any patch
          out.println(name);
          //a try with patch 1 DEPRECATED
          out.println("patch 1:");
          BufferedReader reader =
          new BufferedReader(new InputStreamReader(new StringBufferInputStream(name), "cp1255"));
          String patch_name = reader.readLine();
          out.println(patch_name);
          //a try with patch 2 which doesn't work          
          out.println("patch 2:");
          String valueInUnicode = new String(name.getBytes("Cp1255"), "UTF8");
          out.println(valueInUnicode);
and now for a test client :
import java.io.*;
import java.net.*;
public class HttpClient_cp1255 {
private static void printUsage() {
System.out.println("usage: java HttpClient host port");
public static void main(String[] args) {
if (args.length < 2) {
printUsage();
return;
// Host is the first parameter, port is the second
String host = args[0];
int port;
try {
port = Integer.parseInt(args[1]);
catch (NumberFormatException e) {
printUsage();
return;
try {
// Open a socket to the server
Socket s = new Socket(host, port);
// Start a thread to send reuest to the server
new Request_(s).start();
// Now print everything we receive from the socket
BufferedReader in = new BufferedReader(new InputStreamReader(s.getInputStream(),"cp1255"));
String line;
File f = new File("in.txt");
FileWriter out = new FileWriter(f);
while ((line = in.readLine()) != null) {
System.out.println(line);
out.write(line);
out.close();
     catch (Exception e) {
e.printStackTrace();
class Request_ extends Thread {
Socket s;
public Request_( Socket s) {
this.s = s;
setPriority(MIN_PRIORITY); // socket reads should have a higher priority
// Wish I could use a select() !
setDaemon(true); // let the app die even when this thread is running
public void run() {
try {
                    OutputStreamWriter server = new OutputStreamWriter(s.getOutputStream(),"cp1255");
                    //String query= "GET /userprofiles/hebrew2test?name=yair"; //yair in Englisg ..
                    String query= "GET /userprofiles/hebrew2test?name=\u05d9\u05d0\u05d9\u05e8"; //yair in hebrew - in unicode
               System.out.println("Connected... your HTTP request is sent");
                    System.out.println("------------------------------------------");
                    server.write(query);
                    server.write("\r\n"); // HTTP lines end with \r\n
                    server.flush();
                    System.out.println(server.getEncoding());
     server =      new OutputStreamWriter(new FileOutputStream("out.txt"),"cp1255");
                    server.write(query);
                    server.flush();
catch (Exception e) {
e.printStackTrace();
