Re: running a jar file...(help immediately)

That is how you create a jarfile, not how you "run it". Now, in which step are you having problems. When creating it, or when executing it?

Then you either did not configure the manifest file properly, or you did not include the main class in your jarfile.

Then, as stated before, you are not using the correct version of java for either your compiling and/or executing.
