Once you have defined your Layers, the WMSLayerTree defines both what layers the server's GetCapabilities
response will contain, and what layers can be used by the service. By doing this, it allows for a
central default configuration to be defined for all layers, and then for a specific instance of the server,
these default layers can be exposed or hidden using the WMSLayerTree, or existing layers can be redefined,
or new layer definitions can be added.
Creating a WMSLayerTree
The WMSLayerTree defines the layers that are exposed through the WMS and also defines the structure
of how these layers are organized. Only the layers defined in the WMSLayerTree are returned in a
GetCapabilites response, and can be defined and returned in a GetMap or GetFeatureInfo query.
WMSLayerTree Rules
The following rules apply when creating a WMSLayerTree:
• The Title element of the layer defined in the WMSLayerTree must match the Name element defined
in the WMSLayerList.
• Each Title element must be wrapped in a WMSLayerTree element.
• Each WMSLayerTree element can contain one or more WMSLayerTree elements.
• There can be only one WMSLayerTree at the root. That root layer can have any number of children,
as can any of those children.
• If more than one root WMSLayerTree is defined in a configuration file, only the first WMSLayerTree
will be exposed through the service.
• If multiple configuration files have WMSLayerTrees defined, the last configuration file listed in the
beans.xml file that has a WMSLayerTree will be the one exposed through the service.
In the following example, the World layer contains the North America layer. The North America layer
contains both the Canada and United States layers.
