Well, JavaBotique is Internet.com's primary Java resource. Internet.com also has CodeGuru which doesn't focus on Java specifically, but does contain a Java forum. At this very forum as well, we have an "Other" section in which Java questions would be perfectly valid in. In any case, I agree with your suggestion but perhaps aforementioned forums should suffice.
<opinion>Java has no place being on the internet. Applets have some limited uses, but they take forever to load and flash can usually handle what applets can handle a little better. Jsp is alright I guess, but it still is not super popular and has that rigid language flexibility</opinion>
