I tried to make a small program in J2ME with a small textbox and when i run it on Sun's Emulator it works fine ... when i run it on Nokia's Emulator it works fine also ... but when i put if on my 7650 the phone tell me that jar file is damage. I tried re-make jar file many times but it doesn't work on the phone. So i tried to make a jad file but there is the same error (and sometimes the phone tell me that jar file and jad one are different).
Can anybody help me ? I must solve this problem for my school final exam
Thank you very much.
My phone --> nokia 7650 (software v. 4.37 - 24-10-02)
