Automatic Install JRE

What options, if any, are there for automatic detection and install or
update of the JRE?
Perhaps with a ruby script. If not, it is probably time to think about
writing one :smiley:

I think there is a nsi (nullsoft) installer script that detects the
JRE on Windows. Also, I think BitRock has an installer that does that
too.

That woudld be pretty slick. I’d love to see someone wire up a simple
installer that could even fetch an OpenJDK build (Java 6 preferably,
Java 7 maybe) and install it.

I’ve also thought about how cool it would be to create bundles for each
platform that include JRE + JRuby all ready to go…

As part of Rawr’s bundle task (for Windows) it uses Launch4J which
takes care of JVM detection (presence and minimum version). If the
JVM isn’t installed it takes you to the download page. That’s been
working pretty good for us so far.
