Java classes need a VM to run on. If you don't have one installed you cannot run them.

So, JRE is the minimum, AND of the right version!!!!
: you can't run a .jar created with JAVA 2 1.4.2 stuff on a machine with only some old 1.2 version.
Because almost every computer you may encounter has at least 1.1 (MSWindows, MAC, LINUX ...)
you might write some tiny JAVA program, targeted on 1.1 that spawns "java -version" to see
if things are up level.
In most cases you can have the right JRE installed beneath the old version if management wants it
to remain there.
;JOOP!
