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!

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.
