Re: Service Program Vs Jar File.

[Joep Beckeringh <joep@xxxxxxxxxxxxxxxxxxx>]

Hi Jake,

The closest comparison is: a program object is like a class file with a 
main() method; a service program is like a jar file containing classes 
with public static methods but no main().

A program object can be called from the command line or from another 
program (or even from a service program); it has one entry point (the 
main() method).

A service program has multiple entry points that can only be called from 
another (service) program.
