thanks for your help
i can see in jar files with winzip , i want it to compile , i want to run it as a windows application (exe)

 

Do you have the files extracted out of the jar? If so, you'll want to find an editor (JCreator, NetBeans, etc) and then you can compile the .java files through that.

 

No, jar files that are designed for mobile devices rely on midp programming, you cannot run them outside of the environment they are designed for, no doubt there is a way to do it, but it's certainly not going to be as simple as just installing java

 

Actually, that's probably true. I was under the impression that he just had a regular .jar file.

 

Thanks Guys
