Re: [OpenMap Users] Considerations for client / server data

Hi Hannes,

The LinkLayer might be a good place to start, there is a
ShapeLinkServer in the package. The
ShapeServerStarter prints out instructions for starting the
ShapeLinkServer if you run the starter without arguments, you have to
provide it with a port number and a properties file to use for
determining it's shape file, how the shapes are colored, etc. The
LinkLayer just needs to be told the port number and server host to
contact (that you gave to the server).

The other client-server possibility you have available is the CORBA
solution located in the src/corba directory.
There are CORBA shape, rpf, dted and vpf servers, with a CSpecLayer
that can display information from any of those servers. There is an
image server there, too, I think. As with any CORBA setup, these
solutions require a little care, but they run well when they are up.

You can also create an RMI solution on your own.

Hope this helps,
