Starting new application, is it possible?

Troubleshooting General Help
1

Hi all!



I’ve got a problem. I’am working on a program, which is based on JME.

It’s a kind of frontend, where you can pick a game and start it. This frontend is a SimpleApplication, and a game

can be anything, for example another SimpleApplication.



I know i can’t run multiple instances of them in the same JVM, so i decided to shut down the frontend

while the current game is running.



My question, is there a way to be sure that the application is closed, and another can be started?



Is it possible to stop a SimpleApplication and start another one in the same program?



If i call stop() then sleep about 10 seconds then there is no problem usually, but these isn’t the

way i’am looking for.



Sorry for my bad english, i’am hungarian! :slight_smile:



Looking forward to hear the answer!

Just use app.stop() and override app.destroy() to know when its actually shut down.

I’ll try it right now! Thanks for the answer!!!

4

It is not seems to be working.



I overrid the destroy() method, but when i start the second application it crashes. :frowning:



Is there another solution?

5

just make sure you call super.destroy() before you start the other app.

6

I call it.



[java]

@Override

public void destroy(){

super.destroy();

notifier.alert();

}

[/java]



This notifier class has a perform() method, which is called when the alert() method is invoked.

The notifier is a field of my main class that holds the SimpleApplication frontend, in the perform()

method I instantiate the new application and start it. It’s really fast tough, as tha frontend closed

the new is opened instantly, it goes for about 1 second then crashes.



Any ideas? :frowning:

Does the second app start normally? How are you starting the second app? Is it a new Java instance or the same Java instance?

8

It is the same java program, the other application is another instance of SimpleApplication, so it is in the same JVM.



If i stop the first, then sleep about 10 seconds and start the other, it starts normally, but only if the first is not in fullscreen. :S

Up up up! :slight_smile:



Any ideas on how to shut down a SimpleApplication and start a new one? :frowning:

It takes some indeterminate amount of time for the first app to shutdown. You might want to rethink your approach.

11

So there is no way to determine if a SimpleApplication has been sucessfully shut down?



I think about watching threads running or something like that…?
