Dear Experts,

I have a jar file with 2 main classes. I want to execute the jar file specifying some input to start with different main program at different times. How to do that?

package order:
com.utility
-mainclass1.class
-mainclass2.class

It is packaged into classes.jar.

Best Regards.

write a batch/script file, which takes the input and launches the appropriate class!
