27 /**
28 * Implementation of the <code>EndpointMapping</code> interface to map from the qualified name of the request payload
29 * root element. Supports both mapping to bean instances and mapping to bean names: the latter is required for prototype
30 * endpoints.
31 * <p/>
32 * The <code>endpointMap</code> property is suitable for populating the endpoint map with bean references, e.g. via the
33 * map element in XML bean definitions.
34 * <p/>
35 * Mappings to bean names can be set via the <code>mappings</code> property, in a form accepted by the
36 * <code>java.util.Properties</code> class, like as follows:
37 * <pre>
38 * {http://www.springframework.org/spring-ws/samples/airline/schemas}BookFlight=bookFlightEndpoint
39 * {http://www.springframework.org/spring-ws/samples/airline/schemas}GetFlights=getFlightsEndpoint
40 * </pre>
41 * The syntax is QNAME=ENDPOINT_BEAN_NAME. Qualified names are parsed using the syntax described in
42 * <code>QNameEditor</code>.
