A J2ME application that connects and read data from HTTP protocol

This example shows you how to connect and read data from a http protocol. When you implement it and run it from your mobile device, you have to change the url from localhost to a real hosting address. (Like http://www.ftechdb.com/somefile.txt)

public class Midlet extends MIDlet {
private Display display;
private Form form;
public void startApp() {
display = Display.getDisplay(this);

form = new Form(“Http Example”);
StringBuffer buffer = null;


// you could use other http://www.something.com/file.html as a example

String url = “http://localhost/shaon.txt”;

StreamConnection conn = (StreamConnection) Connector.open(url);
InputStream in = conn.openInputStream();

buffer = new StringBuffer();
int ch;

while ( (ch = in.read())!= -1){
buffer.append( (char) ch);

catch(Exception o){

form.append(new StringItem(null, buffer.toString()));

public void pauseApp() {

public void destroyApp(boolean unconditional) {
