I'm not saying this is directly relevant to Freenet, but it is one of the cooler Java-related things I have seen in a while:
http://code.google.com/webtoolkit/ I think this is what they used to create GMail. Basically you get to write in-browser apps in Java using a stripped down API, and they are compiled to Javascript! It incorporates RPC stuff for reasonably seamless communication between the browser and the server. It seems to be designed to make development of web applications much more like developing normal applications, which makes a lot of sense. On that subject, exactly when did the web turn from being a document retrieval system to being a platform for sophisticated client-server applications - I guess it was some time in 1993 when someone thought up CGI. Ruby on Rails eat your heart out :-) Ian.
