[Zope] Newbie question:Java and Zope

Hello all I am approaching Zope and I am very convinced about its features. The only question that hits me is how to extend it outside Python and Perl. Not that I do not like the two languages, but I have already a good investment in Java classes and knowledge, and I was asking myself if it was possible to join the two. Therefore I ask if somebody can give me some idea if possible, how and so on... maybe it is already written somewhere and I'll get the usual RTFM :)))) but nevertheless I'd like to have an opinion. Thanks Stefano
