Hello,
I use the following code for creating a new map with layers
CatalogPlugin catalog = CatalogPlugin.getDefault();
IServiceFactory svf = catalog.getServiceFactory();
List<IGeoResource> resourceList = new
ArrayList<IGeoResource>();
List<IService> services;
try {
services = svf.acquire(new
URL("http://mstaging/cgi-bin/movida/sclmapserver.exe?service=wms";));
for( IService service : services ) {
resourceList.addAll(service.members(null));
}
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Project project = (Project)
ApplicationGIS.getActiveProject();
CreateMapCommand command=new
CreateMapCommand("Zones", resourceList, project);
project.sendSync(command);
IMap map=command.getCreatedMap();
OpenMapCommand omCommand = new OpenMapCommand((Map)
map);
project.sendSync(omCommand);
Should I loop through the service.members to select the right layers? And
how can I use this code to add layers to a map which is already created.
Map.getMapLayers.add() wants a ILayer as parameter.
Best regards,
Johan de Koning

Yes, the catalog has a lookup function that will basically figure out
the best match for your url (you never have to notice if it was based on
a WMS or WFS or shapefile).
For an example of this in action please review the code for loading and
save OWS Context documents.

The programmers guide (included with your default uDig install or on the
webstite) should be a help here - Look in the GIS Platform section on
how to get a hold of georesources without knowing before hand what type
they are. From there you can follow the example you have already found.
