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!
