Headless server opening 'Error In Application' dialog

Troubleshooting SDK
1

Hello,
My headless server just imploded when I tried to attach a null node. The issue was not the null pointer that it threw, but the ‘Error In Application’ dialog that attempted to open. Is there a way to disable it?

Here is how I create the headless server:

[java]AppSettings appsettings = new AppSettings(true);
appsettings.setFrameRate(128);
appsettings.setRenderer(null);
appsettings.setAudioRenderer(null);
appsettings.setUseInput(false);
appsettings.setDepthBits(32);
DataHandler.physics.setShowSettings(false);
DataHandler.physics.setPauseOnLostFocus(false);
DataHandler.physics.setSettings(appsettings);
DataHandler.physics.start(JmeContext.Type.Headless);[/java]

Uhm… You simply shouldn’t attach null… That will crash the update loop no matter if you display an error panel or not…

I know, it was the server having a slight issue; but I can not have a ‘headless’ server trying to open dialogs.

Just override handleError

Ah, thank you!

So if I do this do I need to tell jme3 anything?

[java]
@Override
public void handleError(String msg, Throwable err) {
DataHandler.logger.log(“EXCEPTION”, “PhysicsHandler”, msg);
System.out.println(msg);
}[/java]

No, jME will end the application in this case anyway.
