Hello,
I am new to Java ME and I am trying to run a copied HelloMIDlet application. I
am getting following error when I am trying to run the application:
Running with storage root C:\Users\Niklas\j2mewtk\2.5.2\appdb\MediaControlSkin
Running with locale: Swedish_Sweden.1252
Running in the identified_third_party security domain

1667 classes in the system (including system classes)
17760 dynamic objects allocated (533540 bytes)
2 garbage collections (459436 bytes collected)
And the applicaiton:
import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;
public class HelloMIDlet extends MIDlet
implements CommandListener {
// The exit command
private Command exitCommand;
// The display for this MIDlet
private Display display;
// create a ticker
private Ticker hi = new Ticker("J2ME is cool");
public HelloMIDlet() {
display = Display.getDisplay(this);
exitCommand = new Command("Exit", Command.SCREEN, 2);
}
public void startApp() {
TextBox t = new TextBox("Hello MIDlet",
"Wireless Internet", 256, 0);
t.addCommand(exitCommand);
t.setCommandListener(this);
t.setTicker(hi); // set the ticker
display.setCurrent(t);
}
public void pauseApp() { }
public void destroyApp(boolean unconditional) { }
public void commandAction(Command c, Displayable s) {
if (c == exitCommand) {
destroyApp(false);
notifyDestroyed();
}
}
}
I did try to remove as much code as possible still being able to compile it.
Exactly the same type of error was presented still...
I have another MIDlet in the same projects that works fine.
What is the problem?
Thank you in advance!
Best Regards,
Niklas
