Re: Openmap Applet with LinkServer

Hi Selva,
The easiest way to get this working is to do this: Create a
AreaShapeLinkServer, that extends the ShapeLinkServer in the same way
that the AreaShapeLayer extends the ShapeLayer - that is, it takes a csv
file to organize to a shape file. Specifying the shape file, and the
csv file, can take place on the server side. You could also have the
properties on how you want the areas colored simply read in on the
server side.

If you want to give the client the ability to change those colors, you
can have the LinkLayer specify a propertiesURL property that would list
the coloring preferences of the client, but you'd have to give the
server the ability to use those settings as it's received them. The
hackesh part about doing this is that the propertiesURL file specified
by the client has to know about the shape file and the csv parameters
that it is setting on the server side, without directly asking the
server to find out what they are. At least with the local
AreaShapeLayer, the data and csv file are local, and you can acknowledge
that the user has access to them.

Hope this helps,

Don
