Samsung J750 - "unsupported file type"

[Wobbly]

Have put a few jar and jad files in my daugters phone.. just trying to get a few java games on it as it doesnt come with any outta the box

When I try and run the executable "jar" file I get te error message above..

I am running Samsung PS Studio3 to load the files.

I also have a 2gb card in the phone but at present only have the games saved on the phone memory

Hope this is enough info so that someone may be able to help.

Thanks for looking.

Does the samsung phone in question support J2ME files? Check its specifications.

Make sure the games are J2ME (mobile) games and not computer games.
(Did you download them from a phone site?)

In the Specs....Says JAVA™ JAVA™ MIDP 2.0 and also JAVA™ Download Yes and further yes the files were downloaded from phone site

i get the same problem for my phone

i have tried jar (java) and .sis (idk what it is)
and then jad probably wont work either.

so, then what is a common file format for a samsung j750? and where can i get apps and games with that file?
