I'm not sure how you are configuring an applet to run under Tomcat.
Can you give more details about that?

I'd start simple, and create a derivation of OMGraphicHandlerLayer that
uses RMI to connect to your data source in the prepare() method,
getting/creating an OMGraphicList from that source, and returning it.
If you want more than one layer to access that data source, then I
would create an OMComponent that creates OMGraphicLists from the data
source based on parameters, and let OMGraphicHandlerLayers find the
OMComponent in the MapHandler (in their findAndInit() methods). The
layers would still talk to the OMComponent in their prepare() methods,
returning that list they received from that OMComponent.
