[WARN] [rms ] javacall_file_open: _wopen failed for: ... _delete_notify.dat

If, while trying to launch your midlet in an emulator, you see a message like

<br />[WARN] [rms ] javacall_file_open: _wopen failed for: C:\Documents and Settings\Administrador\javame-sdk\3.0\work\0\appdb\_delete_notify.dat<br />
, know that you are not alone.

People keep desperately asking the same question without any luck.

At least sometimes it helps to just brutally create the missing "_delete_notify.dat", and the emulator starts to execute the midlet as if nothing happenned.
