I'm starting on this now. I'm sure many on this list have faced
the same task. Here are some thoughts, I welcome advise.
Especially advice on the best mechanism to communicate between
client and server (RMI vs. JMS vs. App../Servlet), including
firewall considerations.
Client activities:
On start-up, the client establishes a connection with the server
to log on and retrieve scene data. The scene is created
and the client registers its initial position with the server.
The client recieves a list of other users in the environment, and
creates visual representations for each. A seperate thread is
started to poll the server for updates to position/heading/speed
of the users and movements are reflected in the scene. As the
user moves around the environment, the client sends position/
heading/speed to the server.
Server activities:
On start-up, the server loads scene information and waits for
client connections. When a client connects for the first time,
it is authenticated, static scene data is returned, as well as
a list of current users, then the client is added to the list of
current users. When the client reconnects to report position/
heading/speed changes, it's entry in the list of current users
is updated and other current users in the list are notified.
