To configure an outbound Web Service Gateway, use the "outbound-gateway" element from the "ws" namespace:

<ws:outbound-gateway id="simpleGateway"
                     request-channel="inputChannel"
                     uri="http://example.org"/>

To set up an inbound Web Service Gateway, use the "inbound-gateway":

<ws:inbound-gateway id="simpleGateway"
                    request-channel="inputChannel"/>

To use Spring OXM Marshallers and/or Unmarshallers, provide bean references. For outbound:

<ws:outbound-gateway id="marshallingGateway"
                     request-channel="requestChannel"
                     uri="http://example.org"
                     marshaller="someMarshaller"
                     unmarshaller="someUnmarshaller"/>

And for inbound:

<ws:inbound-gateway id="marshallingGateway"
                    request-channel="requestChannel"
                    marshaller="someMarshaller"
                    unmarshaller="someUnmarshaller"/>

	Note
	Most Marshaller implementations also implement the Unmarshaller interface. When using such a Marshaller, only the "marshaller" attribute is necessary. Even when using a Marshaller, you may also provide a reference for the "request-callback" on the outbound gateways.

For either outbound gateway type, the "message-factory" attribute can also be configured with a reference to any Spring Web Services WebServiceMessageFactory implementation.

For the simple inbound gateway type, the "extract-payload" attribute can set to false to forward the entire WebServiceMessage, instead of just its payload as a Message to the request channel.
