[OpenMap Users] Help on designing OM Server Client using RMI

Dear OM Users Group,

We are migrating an OM app from standalone to run on a server. We would
like to follow the MVC pattern with the model on the server, and a thick
client for the view. We are having trouble transferring the MapHandler
instance over RMI to the client. We get a EOF exception. This could be
that the MapHandler has too many references to other objects on the server
side and timeout issue?

We need a better way to design things.

Our requirements include:

    1) client side viewing and editing of model data
    2) updating of OMGraphics on the server as the model/simulation evolves
    3) we would like a Swing UI on the client side instead of web page. (we
could try using Ajax, but we are more comfortable with Swing).

Has anyone out there attempted this łthick client˛ approach? Any
suggestions and guidance is greatly appreciated.

Thank you,
