Java libraries to manage CSS explosion and or reuse?

Java Q: I like CSS for simple web pages but loathe it when it comes to real world sites because you get css explosion and lots of repeating.

I am tempted to use Sass and or Compass but they are Ruby programs which will most likely require some interesting Maven + JRuby love to get working for Java Web app dev. This also makes it difficult if you are using Eclipse or any IDE that supports synchronization with a running web app.

Is there a better alternative for the hell that is CSS in the hell that is Java?
