Just wanted to let people here know about a toolkit we've created for making the standard Swing components database-aware. We've been working on it for over a year and open-sourced it on SF in September of 2003. There may be some components or design ideas that could be of use to JDNC developers, although currently it is most applicable at the J2SE level rather than the J2EE level.
If we can be of assistance, just let us know.
