Hi,
working on J2ME application i found very usefull this logging library:
Microlog -> http://microlog.sourceforge.net
This can be used instead of your Log to provide a powerfull "on device" debugging because of it's bluetooth clinet/server and internet logging features you can watch you log directly on your pc instead that on your mobile :)
Take a look, this can be interesting for a feature implemetation of your library.
I know that your Log class is more light but this can be very useful in development phases.
Regards
Thank you for the hint!
