No adapter for endpoint; Is your endpoint annotated with @Endpoint, or does it implement a supported interface like MessageHandler or PayloadEndpoint?

I had a similar error message. My problem was in request and response class that I generated from XSD. It missed @XMLRootElement annotation. This caused that description of operation (in WSDL) and description of implemented method (in Endpoint) did not match. Adding JAXBElement to my endpoint method solved my problem.

import javax.xml.bind.JAXBElement;

@PayloadRoot(namespace = "http://foo.bar/books", localPart = "GetBook")
@ResponsePayload
public JAXBElement<MyReponse> getBook(@RequestPayload JAXBElement<MyRequest> myRequest) {
