exactly, the idea is to avoid JEE clustering and the http load balancer. It's for stateless applications. It's true I have to think in a better way to implement this local cache. I my last applications I haven't use JEE stack, at least during the development. I'm using just jetty+guice+warp-persist+dwr+javascript. One of the requirements was the statelessness of the application, if I need to temporary save something, I do it on the client using javascript, if it's a private thing, I do it using encrypted cookies. All those things can sound strange at first thought but it improved a lot the development speed due to the fact that everything integrates with guice, every object is managed by guice.
