problem starting the app

hi, i have learned java for about 3 months then i started deploying bb apps since 2 days ago so i am a begginerSmiley Happy.


i created a gui app before and it worked fine but i had 2 much trouble to let it work on a real(physical) blackberry when i tried to open the .jar file on the bb it told me "907 invalied jar descriptor missing required attribute midlet-1"

here is the line which contains "midlet-1"

MIDlet-1: ,img/icon.png, 

well it looks that it has something wrong but i don't know what to do.


after searching alot in many forums i extracted my .cod to the bb and installed the app using the .jad file and it worked fine.

but i want to know what if i want to install the app using the .jar file what do i do?



i am using eclipse blackberry java plugin 1.3.0
