Samsung U600 Java error

[flordesnor]

I can't get java games installed on my U600.
This is what I tried:
1: Download a Java game (only a .JAR file)
2: Created JAD file using JADMaker 1.1 (http://www.tucows.com/preview/347348)
3: Upload the files (.JAR and .JAD) to my U600 phone memory (not the extended memory).
4: Enabled Java install via: *#9998*4678255#
5: Went to to the Other Files folder >> Selected the .jad file >> Pressed Options (Left touch key) >> Then I should get: Message displays: Do you want to install >> Press Yes to install. But I got this error: "java-error invalid format"

Has anyone seen this?
Is there a fix for it?
Any ideas or suggestions?

Firmware: U600XXGG3
swver: rev 0.2
hwver: rev 0.2

Thanks!

Hello,
En general, cela signifie que le jeu n'est pas compatible pour diverses raisons comme la resolution de l'ecran.
Pourrais tu m'indiquer la procedure en detail pour uploader un jeu dans le U600
Merci d'avance

Sorry I answered in french.
Generally whe you have this type fo message that means that the game is not compatible because of the resolution of the screen or other reasons.
Please could tell me in detail how to proceed in order to upload a java game
Thank you
