Bundling JRE for a Luddite

[Alan Bomberger]

I have an application that I developed using Netbeans.  I have kept
it up to date by dropping a new jar file into the application bundle
(built so long ago I don't remember how -- jarbundler?)  Besides me there
is one other user.  I recently had to update the javaapplicationstub.

I don't really want to re-learn java development and I have quite
a lot of data in this proprietary format (www.waldenpond.com/thinker).
When the javapplicationstub stops working, this application is dead.

Is there a generic JRE bundled application into which I can
drop my jar file (replacing the application) and tweak the plist
without having to start over with xcode/ant/etc.  I just want to
keep using this application as I am no longer interested in development.

I would do this for java 6 and possibly java 7.  Mike directed me
to this list for help.

Thanks
