A WSDL Resource represents a stripped down version of a Service type.
If you are not already on the Browse control click the Catalog tab at the upper left corner of the console.
In the left navigation panel, expand the Resources node.
Click the WSDL link. This will load the WSDL Resources view in the central panel.
Click on the List all WSDL resources link. A Default view of all the visible WSDL resources, sorted A-Z appears in the view pane. Included are fields for WSDL's service name, target namespace, and a linked URL showing its location.
You can filter these results by selecting a field from the filter list box, entering a partial filter string in the edit field, and clicking the filter button.
