invalid application

[IronWolf]

Hello,

I am new to MIDlets development, but I wanted to try to develop simple MIDlet for my Nokia 6103. I used Carbide.j. I created a new class, then application package. Before creating application package I changed default device to "Prototype_4_0_S40_128x160_MIDP_Emulator". .jar and .jad files were created. I run successfully my MIDlet on an emulator. It worked fine. Then I transferred .jad file to my mobile. When I tried to execute it I got a message saying: "Invalid application. Delete?"

I guess, somehow, I have developed application for different device type. As I said, I wanted it to work on my N6103. What setting should I change?

I would appreciate any suggestions.

Cheers,

IronWolf

Hi IronWolf! Welcome to Nokia Discussion Boards!!

Please make sure that your JAD and MF entries are correct and they match each other. Also ensure that you have not used any Classes/methods that the device does not supports.

Hi,

Thank you for your suggestion.

Manifest file looks like below and matches phone specs:

MF:
Manifest-Version: 1.0
MicroEdition-Configuration: CLDC-1.1
MIDlet-Name: HelloMIDlet
MIDlet-Vendor: MyCompany
MIDlet-1: HelloMIDlet, , HelloMIDlet
MIDlet-Version: 0.0.1
MicroEdition-Profile: MIDP-2.0

Spec:
MIDP 2.0
CLDC 1.1

Code is quite simple as well:

import javax.microedition.lcdui.*;
import javax.microedition.midlet.*;

public class HelloMIDlet
extends MIDlet
implements CommandListener {
private Form mMainForm;

public HelloMIDlet() {
mMainForm = new Form("HelloMIDlet");
mMainForm.append(new StringItem(null, "Hello, Test"));
mMainForm.addCommand(new Command("Exit", Command.EXIT, 0));
mMainForm.setCommandListener(this);
}

public void startApp() {
Display.getDisplay(this).setCurrent(mMainForm);
}

public void pauseApp() {}

public void destroyApp(boolean unconditional) {}

public void commandAction(Command c, Displayable s) {
notifyDestroyed();
}
}

Cheers,

IW.

May be you should give a try with changing the MIDlet-Version number to 1.0 or so. Just a blind try. I dont find any other mistakes in my quick check.(May be I have missed!)
