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

Question

I am struggling with an Spring-WS with JMS example. I set the Spring-WS and JMS wiring as per the Spring recommendations. But I kept getting following error. I dont know how to bypass this issue, any help will be highly appreciated:

My Web Service Wiring is

My End point code is

@ResponsePayload
public String  store(@RequestPayload JAXBElement<Image> requestElement) throws IOException {
    Image request = requestElement.getValue();
    return imageRepository.storeImage(request.getName());
}

My Schema is

My Client Request is

Can some one help?

Answer 1

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) {
    ...

See this blog for more details: spring-ws: No adapter for endpoint

Answer 2

I was using WSDL file and did as below, then it worked.

  @PayloadRoot(namespace = "http://www.myservice/v1.0/query", localPart = "queryRequest")
  @ResponsePayload
  public JAXBElement<QueryResponse> queryAddrLocation(@RequestPayload JAXBElement<QueryRequest> queryRequest) {
    System.out.println("Welcome to " + queryRequest);
    return createJaxbElement(new QueryResponse(), QueryResponse.class);
  }

  private <T> JAXBElement<T> createJaxbElement(T object, Class<T> clazz) {
    return new JAXBElement<>(new QName(clazz.getSimpleName()), clazz, object);
  }

Answer 3

I had a similar error. the problem is that the request and response generated from XSD/WSDL missed the @XMLRootElement annotation. By adding JAXBElement to the endpoint solved the problem.

private static final String NAMESPACE_URI = "<targetNamespace>";

@Autowired
Service   service;

@PayloadRoot ( namespace = Endpoint.NAMESPACE_URI, localPart = "name" )
@ResponsePayload
public JAXBElement < Response > Create ( @RequestPayload JAXBElement < Request> request ) throws Exception
{
ObjectFactory factory = new ObjectFactory ( );
Response response = new Response ( );
Request req = request.getValue ( );

response  = this.service.call( req);

return factory.createResponse ( response );
}

I'm not sure how your complete Endpoint looks, but the class should be annotated with @Endpoint or it should implement MessageHandler or PayloadEndpoint.

On other thing you can play with is the method signature. Spring-WS' endpoint mapping is pretty intelligent: it tries to map input and output classes from your method signature with the WSDL file. Are you sure a String is the @ResponsePayLoad, not a StoreImageResponse?

For example, here's the method signature of one of my endpoint

@PayloadRoot(
    localPart = "GetHiredCandidatesRequest", 
    namespace = DEFAULT_NAMESPACE
)
@ResponsePayload
public GetHiredCandidatesResponse getCandidates (
    @RequestPayload GetHiredCandidatesRequest getCandidate,
    MessageContext messageContext) {
    ...
}

Which is defined in my WSDL like this:

<wsdl:operation name="GetHiredCandidates">
    <wsdl:input message="tns:GetHiredCandidatesRequest" name="GetHiredCandidatesRequest"></wsdl:input>
    <wsdl:output message="tns:GetHiredCandidatesResponse" name="GetHiredCandidatesResponse"></wsdl:output>
</wsdl:operation>

Do you see how it's mapped? Perhaps you're missing something like that in your signature.
