Running alternate class in jar file

[Tom McAmmond]

I know that if I specify the main class in a jar file's manifest I can just run

java -jar jarfile.jar 

But what if I have two classes in the jar file with a main() method, say a utility.class and a mainclass.class, and once in a while I want to run that utility.class instead? Is there a way to do that? Or do I have to remove the main-class from the manifest?

Thanks for any help

Forget it - I answered my own question. For the curious (because I always hated reading someone's question that was like mine that later only said "I figured it out"), you do it like this:

java -cp jarfile.jar classname
