[udig-devel] Method to directly acquire a layer from WMS

[Jesse Eichar]

If you have the WMS in the catalog you can find it directly by:

CatalogPlugin catalog = CatalogPlugin.getDefault();
catalog.getLocalCatalog().findByID( new URL( “http://localhost:8080/geoserver/wms?lService=WMS&Version=1.1.1&Request=GetCapabilities#tiger 
:tiger_roads” );
