Pushing the envelope

Just been playing with the EOB-Prevayler demo. Very cool. The app that wouldn't die. Bounce the client: state is preserved. Bounce the server: state is preserved. Database Not Included (or required). Even cooler: open 3 or 4 windows and watch them all update when one is changed. Very, very cool.

Transparent RMI. There's an interesting article over on JavaWorld: "Empower RMI with TRMI". Transparent RMI makes it simpler to create RMI services. No more extending Remote and having every method throw RemoteException & it also centralizes error handling on the client side. It appears to be using dynamic proxies to simplify things... I need to investigate this further. [Otiose Cognitions]

While you're at it, have a look at altRMI.

Persistence.... I've been looking into a lot of different persistence strategies for "Java" lately for projects I'm working on at work. Currently most of our projects still use hand-coded SQL (JDBC) which is far from desirable. [Otiose Cognitions]

I hear good things about Kodo JDO. Might be worth a look.

Free learning from MIT. Nice of them.
