Trying to make a jar file?

[klebian]

Hi, I wrote a program as a study tool for memorizing stuff, for academic challenge, and a teammate asked me for the program. He does not have jcreator- he wants to be able to run my program by simply clicking on the file. I think that a jar file suits this purpose, because I know someone who has used a jar file to distribute his program without the user needing to open jcreator (which is a function that is obviously necessary for programs).

I searched # for how to create jar files, and was fairly thoroughly lost. I have 3 .java files (which I can obviously combine into 1 if necessary), and a .dat file from which input regarding the stuff being memorized is read. Can someone help me? I'd greatly appreciate it.
Thanks,

You could use a batch file, assuming you're on Windows.

yeah, .bat works well.

As an example, go to notepad:
type in the open document "command.com" without the quotation marks obviously
Save it as command.bat
You just made a command prompt, and it will work in schools as well, even with the command prompt disabled...

Thanks! This is much clearer than other websites I found. Unfortunately, when I click on my jar file, I get the message "Failed to load Main-Class manifest attribute from C:\...filename.jar"
any idea what the problem may be?
