How to get .jar files to work on mobile phone

Hello

How can I get .jar files to work on mobile phone? I use EclipseME with WTK 2.2, and my program is working in the emulator in Eclipse, but when I try to run the .jar file on my SonyEricsson mobile phone, I just get an error message "the installation failed".

I have just moved the .jar-file to the phone with my USB cable.

I am a bit confused, because regular java programs uses the main method to start the program, what does J2ME programs use? I use MIDlet/WTK 2.2.
