I am forwarding message becouse it hasn't been delivered:

I would like to consult all of the OpenMap users and developers to check
if this idea is the only way to provide data for APPLET:

1. I need to implement a scalable solution for providing SVG symbols
from server to client the symbols will be produced on the server side
and only transferred to OMApplet.

2. the data is produced as fallows -> a servlet produces HTML and applet
TAG invoking OMApplet -> then the applet localizes the RMIRegistry with
registrated service providing all the layers preapered for the SID
(SessionID pointing the user session state)

3. when the applet localizes all the layers it begins to download
grphics (and also data) objects placed on the layer using RMI remote

this is what i have in mind the servert uses JDBC to preaper the Layer
list (and graphic obj) for each user logged in the system.

is there a simplier way to pepare a personalized data for OMApplet - i
should state that creating an open-map.properties file and inserting it
in the JAR of the whole applet is the last think i want to do becouse of
the reusability issues.

Has anyone any comments of the idea i presented, what do You think is it
worth implementing??

I am already implementing a RemoteLayer Abstract class which will be
placed in the Applet and will connect with it stub on the server
preparing the SVG symbols from the SymbolReferenceLibrary and then
posting it as the projectionChanges and so on.

I am going to implement the mechanisms using two main methods of the
Layer implementation prepare() and projectionChange()

Thank You for any comments
