Add an EndpointAdapter that adapts to a MethodEndpoint for a methos with one Source param containing the payload [SWS-254]

[gregturn]

Tom Lambrechts opened SWS-254 and commented

Make an adaptor that makes it possible to use the PayloadRoot annotation on a method taking a single parameter javax.xml.Source. The parameter should be a java.xml.Source reference to the payload of the message.
The Source param is very convinient when implementing XPath in the endpoint without using the XPathParam annotation.

@PayloadRoot(localPart = TRACKING_MESSAGE_INFO, namespace = NAMESPACE_XQ)
public Source invokeTrackingMessageInfo(Source request) throws Exception {...}

This issue is solved by adding the class SourceParamMethodEndpointAdapter that adapts to a MethodEndpoint and supports all methods taking exactly one Source parameter.

We already have the PayloadMethodEndpointAdapter, see http://static.springframework.org/spring-ws/site/apidocs/org/springframework/ws/server/endpoint/adapter/PayloadMethodEndpointAdapter.html

Is the SourceParamMethodEndpointAdapter any different than the PayloadMethodEndpointAdapter?

It puzzled me too for a while, but there is a big difference.

If you define an endpoint with the annotaion PayloadRoot and MethodEndPoint is created (and that is what we want because we can have more than one method with a parameter source and and annotation @PayloadRoot)

The PayloadMethodEndpoint Adaptor can only handle classes who implement PayloadEndpoint.

The SourceParamMethodEndpointAdapter can handle MethodEndpoints that have an annotated method witch takes a sigle source param.
If you look to my sample you see where I want to go to.

Actually the PayloadMethodEndpointAdapter is a special case of a SourceParamMethodEndpointAdapter.

This has been implemented as part of SWS 2.0.
