Javascript, not Java. But support is optional and only a few reading systems (those based on webkit?) currently support it (iBooks and I believe Kobo's Android and iOS apps do, and I think calibre's epub viewer does as well).
Mobipocket specification also included Javascript support way back, but I'm not sure which if any of the reading apps actually implemented it.
Taking this a step further, there is an .epub file floating around out there called 'jquery on iBooks', which demonstrates the ability to use jquery UI objects in iBooks (and Kobo).
But just because you
can do something, does not mean that you
should do it. For example, I've checked out a few 'enhanced ebooks' (embedded audio and video objects) and can't say it added positively to my reading experience. But things like popup footnotes are a no brainer. It will be important to implement fallback mechanisms so reading systems without JS support can at least know what they might be missing, or get a useful, if less slick, experience.
