Sun has a version standard that defines at the package
level the format of an interface specification version
(major.minor.edit), the format of an implementation version
(a string, comparable for equality but not for less than/
greater than), and the names of the appropriate labels to
use for them in the MANIFEST.MF. I think it even showed a
set of methods on one of the system classes to look all this
data up and compare interface versions. It has been out
there for some time; I have a dog-eared hard copy at the
office that I printed over a year ago and I don't think it
was recent then. A search on the http://java.sun.com site
should scare it up.

Of course, Jar versioning doesn't help you particularly for
RMI, does it? Or does it?

It would be very nice if the version tab in Windows and the
version checking logic in InstallShield were smart enough to
pick up jar versions, but I don't see that happening any
time soon.
