Using a Jar File in Dos/Batch Script

I have a jar file that I successfully run from the windows command line below:

Mathprog.jar invokes a computeXYZ method using 3000 as a argument and outputs a value when finished. That works perfectly.

The problem that I'm having is that mathprog has more than one method and I want to find a way to invoke more methods than computeXYZ from the command line. I'm certain that this is not the proper syntax but what I envision is being able to say something like:
c:\>mathprog.computeABC.jar 8000
c:\>mathprog.computeMNO.jar 500

What's the correct way of doing this? I'm new to jars.

Sorry, that won't work. You can set a main() method in a class that will run when the jar is executed. In order to do what you want, you'd need to a create a new .jar file for each of the methods.

I agree. Here's the link:
