Home Sweet JVM
However, if you’re willing to run wherever there’s a JVM, then we can do some interesting
things.

write once run
anywhere?

write cext compile
everywhere!
putting a c compiler on your production box always felt to me like

11. Warbler Uses

12. Portable
Web applications

13. Ruby GUIs

14. Distribution without
source code

15. No control over
deployment

16. Simplify
deployment
package once, copy to all the machines where you need to deploy it.
no setting up ruby, gems
also can version easily since JRuby is bundled in the war file.
