Hi all,
I do have the same situation: migrating from 1.5.7 to 2.0.0.
Everything was working perfectly good, then I added the @Endpoint to the endpoints and in the spring context removed all the mapping. Just have the <sws:annotation-driven /> and <sws:dynamic-wsdl />
But then i get the error "No endpoint mapping found".
They just work when i explicit set the bean for the Endpoint class and add in a mapping for PayloadRootQNameEndpointMapping.
I have no idea why the classes annotated with @Endpoint are not being mapped as they should. 
the problem is that using the spring-ws 2.0 i have to add @Endpoint AND also map all the endpoints in a XMl file.... 
Any tip?
