[mapserver-users] Which Java JDK?

[Stephen Woodbridge]

Sorry, if this is a little off topic.

I want to get a Java JDK for my RedHat 6.2 Linux box so I can try and
make some changes to the Rosa applet. I want the applet to run in the
existing browsers.

Which Java JDK should I get? 
Do I need to worry about Java 1 vs Java 2?
Where should I get it from?

Thanks for any help you can offer,
  -Steve
