Running a java program without eclipse / JAR Files?

[littledrummerboy]

I've created a java-based version of monopoly in eclipse for my computer science class that has tons of classes and images. I know how to use it in eclipse but i was wondering how to run it on another computer that doesn't have eclipse so that a friend could run it on their computer. Someone mentioned something about a JAR file, but I wasn't sure how to create one of those or if this was the right thing to do? Can anyone help?

If you created a jar file with all the class files and a manifest file, you can pass that jar file to anyone with a JRE installed and it should execute.
Read the JDK doc for the jar command. jar comes with the JDK.
Also do a search on the forum for examples of jar command usages.

Also look at using Eclipse to create the jar file.

thanks, i've been looking at them a little but i'm getting a little confused as to how i create on in the first place after seeing things like

Create jar file
jar c[v0M]f jarfile [-C dir] inputfiles [-Joption]
jar c[v0]mf manifest jarfile [-C dir] inputfiles [-Joption]
jar c[v0M] [-C dir] inputfiles [-Joption]
jar c[v0]m manifest [-C dir] inputfiles [-Joption]

on oracle..

You told the Eclipse jar wizard where it could find the file to be used for the manifest entry of your .jar file; the manifest file isn't there. Or (alternatively) you didn't put in a manifest entry in your .jar file at all. Check your .jar file with a zip utility and see what's in there.

kind regards,

You were right, I was missing a manifest entry, it works perfectly now, thanks a lot!
