What happens when you erase appdb folder

I tried to run a j2me application that I'm developing at work and I got the following error:

Connecting to on port 2800
Waiting for KVM...
Waiting for debugger on port 2419
Connection received.
Running with storage root C:\Documents and Settings\moliveira\j2mewtk\2.5.2\appdb\DefaultColorPhone

I made a mistake and the content of appdb that belongs to Sun Java  Wireless Toolkit 2.5.02_1 for CLDC has been erased. Some configuration file was deleted which caused the error described above.

The fastest mode to solve this problem:
  • erase the folder named j2mewtk that is inside Documents and Settings under another folder named as your login user. (For instance, C:\Documents and Settings\moliveira\j2mewtk\)
  • run the Wireless Toolkit. It will recreate the folder j2mewtk and the problem will be solved.
