I'm continually impressed by the quality of questions and answers that get posted to the JINI-USERS mailing list. To do my bit for the Community, I've created a Jini Wiki where I (and hopefully others) will actively post those nuggets.
I'm currently working on a way to integrate HyperGraph with SnipSnap to provide visual cues for navigating the Wiki.
P.S. Artima has links to other excellent Jini Books, FAQs, Web sites, articles, papers, and code examples.
I am very interested in a SnipSnap/Hypergraph integration, therefore I was very happy to find this log entry. Can you post some information on the implementation status? If you need someone who helps testing the integration at some point in time, let me know:)
