MIDPLogger
Developing J2ME/MIDP applications has its challenges. Not least amongst these challenges is the reliance on emulators for testing and the usual compliance issues that exist with the J2ME devices themselves. When developing a MIDP application using an emulator, a number of possibilities exist:

1. Your MIDlet works perfectly in the emulator....and works perfectly on a real device. Fantastic!
2. Your MIDlet doesn't work quite as expected in the emulator, but works perfectly on a real device. Not bad at all!
3. Your MIDlet works perfectly in the emulator....but doesn't work as expected on a real device. Bad. Very bad!
4. Your MIDlet doesn't work anywhere. Definitely not good!

MIDPLogger is really designed to help with scenario (3), although it may well be useful in (4) as well.

To help debug issues that exist when running a MIDlet on device, MIDPLogger provides an on-device log file, log writer and log viewer capability. By integrating the MIDPLogger class within your MIDLet, you can write debug/trace information to an on-device database (and also to the console if you like, for when you are running in your emulator). You can browse and otherwise manage the on-device log file using the MIDPLogViewer MIDlet, by adding it to your MIDlet suite.
