Hi Jerry, Bear in mind that the brand-new revlet system isn't even finished yet. It is still in alpha, and there's still plenty of functionality to add before the shipping date. Hence, few people are going to take a dive deep enough to hit these sort of questions. But I'll give it a shot.
Not yet implemented, but scheduled for the release version, is the ability to interact between the revlet and the containing web page via JavaScript; as Java applets can do the same thing, you could setup JavaScript as the go-between messaging system between revlet and applet. But there's no way to try this just yet as the mothership's engineers still have to finish that. What you can do, however, is use socket communication. Your Java applet can open a ServerSocket on an agreed-upon port, and the revlet can open a socket to this port and read from it or write to it. You wouldn't need anything extra and can start experimenting today. The tricky part in this scenario is the browser security model: both Java and the RevWebEngine place their in-browser parts in a sandbox where they can't do any harm (such as reading/writing files, opening sockets, connectiong to databases,...) And the user has to explicitly allow them out of this sandbox environment - via a security permission dislog box that sternly warns you to only do this if you really trust whoever wrote this code.
