import java.io.*;

public class httpTest extends MIDlet {
private Display display;
private CommandThread commandThread;

public httpTest() {
display = Display.getDisplay(this);

public void startApp() {
commandThread = new CommandThread(this);

public void pauseApp() {

public void destroyApp(boolean unconditional) {

public static void quitApp() {

class CommandThread extends Thread{
MIDlet parent;
public CommandThread (MIDlet parent){
this.parent = parent;
public void run(){
String url = "";
HttpConnection sc = (HttpConnection)Connector.open(url);
DataOutputStream dos = new DataOutputStream(sc.openOutputStream());
DataInputStream dis = new DataInputStream(sc.openInputStream());
String contant = "";
int ic;
while((ic = dis.read())!= -1){
contant = contant + (char)ic;
Form f = new Form("new http test");
