it's probably nothing but my app does not seem to start on my hard blackberry device. On the Emulator i have no problem at all, the Auto Start worj just fine. but on real devices, i had no luck.

here is my case

The project name is "MISyncAgent"

The class with the Main is called "SyncAgentApp"


the main is pretty simple

public static void main( String[] args )
{

//TEST
SyncAgentApp.addMessageToFolder( SyncAgentApp.messageFolderName, "BEGIN" );
SyncAgentApp app = new SyncAgentApp();
app.enterEventDispatcher();

}

the addMessageToFolder methode public static use to log some traces

the project properties are

Project Type : CLDC Application
Ribbon : set to none
Auto-run :Enabled
System Module : Enabled
Startup Tier : 6

BTW: My application is well Signed

i'm using the RIM Device Java Library 3.6 Release

So... Why it's running Very well on the emulator but not on my devices, i have try 6 Differentes device, all with the same result.

Is this something that i have to do with the JavaLoader? Do i have to tell to the JVM where to find the "main" Methode....
Please help!

Did you sign the APP with a key from RIM? You must do this for an app to run at startup

Yes it is signed

I found my bug, i was using the library import "net.rim.vm.Persistable". it seem taht library required a special Signature, so the App was refusing to start. Instead, i'm using now "net.rim.device.api.util.Persistable". and everything is back to normal. Anyone can add comment on that?

The net.rim.vm.Persistable class is a class used by the operating system, while the net.rim.device.api.util.Persistable class is the version that RIM would like developers to use. This is probably because the net.rim.vm.Persistable class is likely to change. Classic case of hiding the things that can change. While the underlying implementation of the Persistable class may change, the public class will change to meet that, thus avoiding massive code breakage.
