Yesterday I met with Wouter van Reeven, here in San Francisco, who
mentioned the RichFaces framework to
me. In particular, people in a JBoss-oriented world are likely to
want to use RichFaces (as well as ICEfaces, Seam,
and Facelets). For ICEfaces, a NetBeans plugin exists (here),
though it works in 6.0 only. I've tried it, it's a pretty cool
thing: you get support both for traditional web applications and
for Visual Web applications. I'm hoping they'll upgrade to 6.1...
