J2ME application can't be open in S40

[suoran3060]

Hi all,

I develop a J2ME application, create package .jar and .jad successfully.

I can run it successful in S40(NOKIA5130) first time.

But if I exit and run again, I can't open it.

The software always stay in waiting interface, "opening ……", and can't run it.

I don't know why. Waiting your's answer and thank you very much.
(The other, I can run it in NOKIA 5310 successfully, no any problem.)

Hello,

Can you please share the startup method and constructor code of your midlet?

That's not complexity exactly, I think. And if I use the jar that has NOKIA certificate, that' ok in 5130.

The constructor does nothing, and some function begin from startApp().

protected void startApp() throws MIDletStateChangeException {

MWH.midlet = this;
MWH.display = Display.getDisplay(this);

MWH.display.setCurrent(new view.Welcome());
}
