two mains in one jar

[Ann]

I have an application that produces a set of
jpg files. I jar it up and everything is great.
I also have a utility program I use to view the
jpgs. I put all of this in a single jar file and set
Main-Class: NewDraw
(name of the first prog) in the manifest file.
java -jar NewDraw.jar
runs the first program.
How can I run the second program?

Don't use the -jar flag. Instead, list the jar in the classpath, and name
the second program's class on the command line.

what about adding a Switch-Main-Class which parses the command-line and
starts Main1 or Main2 based on the parameters?
