When I try to receive sms in j2me this code just does nothing. When app is launched from startApp() a new thread is started which calls run() where it starts listening for a message. Please have a look.

public class Receiver extends MIDlet implements Runnable {
Display display;
Alert showMessage = new Alert("Msg", "Checking inbox..", null, AlertType.INFO);
public void startApp() {
Thread t = new Thread();
t.start();
}
public void run() {
try {
// Time to receive one.
//get reference to MessageConnection object
showMessage.setTimeout(Alert.FOREVER);
display.getDisplay(this).setCurrent(showMessage);
MessageConnection conn = (MessageConnection) Connector.open("sms://:50001");
//set message listener
conn.setMessageListener(new MessageListener() {
public void notifyIncomingMessage(MessageConnection conn) {
try {
Message msg = conn.receive();
//do whatever you want with the message
if (msg instanceof TextMessage) {
TextMessage tmsg = (TextMessage) msg;
String s = tmsg.getPayloadText();
System.out.println(s);
//showMessage.setTimeout(Alert.FOREVER);
showMessage.setString(s);
showMessage.setTitle("Welcome");
display.setCurrent(showMessage);
} else if (msg instanceof BinaryMessage) {
System.out.println("inside else if");
} else {
System.out.println("inside else");
}
} catch (Exception e) {

}
});
} catch (Exception e) {

public void destroyApp(boolean unconditional) {

You need to read up about threading in Java.
Currently, you're starting a new thread which does nothing.
See the Javadoc for the empty Thread constructor:
Your MIDlet implements
Runnable
so you need to pass that into the thread. Try this instead:
