I'm pretty sure I run Java on DOS (or equivalent) every day. There's  
even an example in this thread!

> jruby -S gem install hpricot

You can also kick off any Java application from the command line with  
`java -jar myapp.jar`.

Don't forget that Java also runs on some mobile devices as well. Some  
folks have gotten JRuby running on Android phones.
