Read thought these links on lift view first design it takes some hacking
but it really is critical to understand

Once you understand that you old java beans are either right in the
snippet it gets easier. You do a lot of things were you have a singleton
that keeps a hashmap of lift actors and act as a message broker for
actor messages through the system. This is pretty common for any time
you need a chat or bid type application.The same approach can be used
with amqp connections to legacy "soa" endpoints on the ESB. Allowing you
to ask the message buss for data and dispatch it back into the website
with commit. Makes for a pretty sick flow.
If you have not I would highly recommend buying the early access to Lift
in Action by timothy perrett. It goes through all of this. You will also
need a scala book before you jump into lift! David Pollack has a great one.
