Maybe you should read tutorials? Surely this is NOT a common problem, but wrong implementation of Midlets.
Midlets do NOT run by getting called a main-Method - who generated such a Template? Its completely different from "normal" High-Level-Java-Programming, so forget about what you learned :-) Midlets have a so called "lifecycle". startApp() is called each time the midlet is braught into foreground, ans pauseApp() is called if the platform sends it into the background (some devices can do this, like Symbian onces). A good tutorial can be found here: http://today.java.net/pub/a/today/2005/02/09/j2me1.html Greetings, Markus Martin Milan schrieb: > Hi there - VB.Net / C# coder with a sense of adventure here... > > I've read a few books on Java, and decided to give it a whirl - having > used Eclipse 3.3 to knock together a quick "Hello World" app with Swing, > I've decided to try and create a small application for mobile phones. > EclipseME looks like just the sort of think I'm after then, no? > > So, I've got Eclipse Version: 3.3.1.1 <http://3.3.1.1> Build id: > M20071023-1652 installed to d:\eclipse\eclipse. > I've got the Sun jre1.6.0_03, hidden away in c:\program files... > I've got the Sun Wireless Toolkit 2.5.2 installed at c:\WTK2.5.2. > EclipseME 1.7.7 running as a plugin on Eclipse... > > I've "written" the following as a first midlet... > > import javax.microedition.midlet.MIDlet; > import javax.microedition.midlet.MIDletStateChangeException; > > > public class CMainForm extends MIDlet { > > protected void destroyApp(boolean arg0) throws > MIDletStateChangeException { > > } > > protected void pauseApp() { > // TODO Auto-generated method stub > > } > > protected void startApp() throws MIDletStateChangeException { > // TODO Auto-generated method stub > > } > > /** > * @param args > */ > public static void main(String[] args) { > // TODO Auto-generated method stub > > } > > } > > > In other words - just the stubs...
