Re: Service Program Vs Jar File.

The same?  No.

Similar in concept?  Yes.

A jar file is a collection of class files and other resources that are
used by a java application that are bound at runtime.

A service program is a collection of modules, which contain one or more
HLL procedures, that are bound at runtime.

A jar file can contain a complete application ... including all the
static resources it needs.  A service program can only be used by
another ILE program (*PGM) on the iSeries.

I usually equate service programs to windows DLL's or unix shared libraries.
