If N70 supports filesystem access, you might consider logging and writing to the filesystem...

Can you describe the problem in greater detail?

I have developed mobile application program using MIDP 2.1 . I ported it to Nokia N70. But it fails to run on N70 because N70 supports MIDP 2.0 .How can I run my application program on N70 mobile phone.what is the difference between MIDP 2.1 and MIDP 2.0?
Thanks!

If you are using the Sun Wireless Toolkit try changing your project's properties from MIDP 2.1 to MIDP 2.0.
This can be done from the menu Project -> Settings -> API Selection -> Custom -> Profiles MIDP 2.0.

After pressing OK, rebuilt the project, create the package again (Project -> Package -> Create package), and transmit the jar file to the mobile device.

I hope this works for you!

I had a similar problem while trying to install a j2me app long back(when i was a beginner).
I carefully filled up the 'vendor name' etc into the JAD and unticked the unwanted libraries,this solved the issue.
