Sean,
We liked it so much that a lot of it was integrated into MyEclipse awhile back. The original XDoclet work by Hans Dockter was quite good so we spoke with him and he suggested we use it. So we fully integrated that piece into MyEclipse. We didn’t need the rest of it since we already supported JBoss as well as a ton of other servers.
Net-net, you really don’t need it if you use MyEclipse. 🙂
