Spring WS web service. Adding an attachment to the response using SAAJ - No adapter for endpoint

Question

I am really struggling getting Spring-WS to return a response with attachments. I have managed to get an MTOM version to work but this has some pre-requisites on the client as i believe that the client has to be MTOM enabled as well (please correct me if this is not correct).

What i am trying to do now is to use the standard SOAP with attachment implementation using SAAJ and Spring-WS.

To do this i implemented an endpoint that just attaches an image from the local filesystem to the response.

@Endpoint
public class TestEndPoint {

private SaajSoapMessageFactory saajMessageFactory;

@PayloadRoot(namespace="http://ws.mypackage.com", localPart="downloadMessageRequestSaaj")
    @ResponsePayload
    public JAXBElement<DownloadResponseSaajType> invoke(@RequestPayload DownloadMessageRequestSaaj req, MessageContext context ) throws Exception  {

        DownloadResponseSaajType response = new DownloadResponseSaajType();
        DownloadResponseSaajType.PayLoad payload = new DownloadResponseSaajType.PayLoad();  

        DataHandler handler = new javax.activation.DataHandler(new FileDataSource("c:\\temp\\maven-feather.png"));

            SaajSoapMessage message = saajMessageFactory.createWebServiceMessage();
            message.addAttachment("picture", handler);

            context.setResponse(message);

            payload.setMessagePayLoad(handler);

            return objectFactory.createDownloadMessageResponseSaaj(response);  

    }

    public void setSaajMessageFactory(SaajSoapMessageFactory saajMessageFactory){
        this.saajMessageFactory = saajMessageFactory;
    }

    public SaajSoapMessageFactory getSaajMessageFactory(){
        return saajMessageFactory;
    }
}

The Saaj properties are depency injected as shown below:

<sws:annotation-driven/>

<bean id="soapMessageFactory" class="javax.xml.soap.MessageFactory" factory-method="newInstance" />
<bean id="saajMessageFactory" class="org.springframework.ws.soap.saaj.SaajSoapMessageFactory">
        <constructor-arg ref="soapMessageFactory" />
</bean>

<bean id="myService" class="com.mypackage.TestEndPoint">
    <property name="saajMessageFactory" ref="saajMessageFactory" />
</bean>

When i try to call the above service i get the following error:

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
   <SOAP-ENV:Header/>
   <SOAP-ENV:Body>
      <SOAP-ENV:Fault>
         <faultcode>SOAP-ENV:Server</faultcode>
         <faultstring xml:lang="en">No adapter for endpoint [public javax.xml.bind.JAXBElement&lt;com.mypackage.ws.DownloadResponseSaajType> com.mypackage.TestEndPoint.invoke(com.mypackage.ws.DownloadMessageRequestSaaj,org.springframework.ws.context.MessageContext) throws java.lang.Exception]: Is your endpoint annotated with @Endpoint, or does it implement a supported interface like MessageHandler or PayloadEndpoint?</faultstring>
      </SOAP-ENV:Fault>
   </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

I noticed today that i change the method signature to remove the MessageContext parameters as shown below then i dont get that error:

public JAXBElement<DownloadResponseSaajType> invoke(@RequestPayload DownloadMessageRequestSaaj req)

The problem however is that i need to access the MessageContext to be able to add the attachment. Could be that maybe my configuration is wrong somewhere?

This was driving me mad the other day but with a different parameter set. Does it give the error if you remove the "@RequestPayload DownloadMessageRequestSaaj req," Part of the payload method parameter? If so try a different version of that class. I was trying to do it with a org.jdom.element, but that kept giving the error. I switched to jdom2 and then it suddenly worked. I guess theres some incompatibility with the older jdom - perhaps theres a similar issue here. — Davos555, Jul 13 '12 at 13:09
I tried changing the method parameter to "public JAXBElement invoke(MessageContext context )" but it still gives the same error. — ziggy, Jul 13 '12 at 16:49
Just noticed that the error does disappear if i remove the MessageContextParameter but i need that to be able to add the attachment to the response. — ziggy, Jul 13 '12 at 17:06
Following [this answer](http://stackoverflow.com/a/6446238/983430) worked for me. — Amos M. Carpenter, Nov 10 '14 at 06:10

I believe in either case your client will need to be aware of the attachment so I would recommend sticking with mtom (as it is becoming the standard)

check which version of spring-ws you are using and which maven group-id you are using. i was getting the same error because this feature was recently added (I think?).

try this entry and remove any other spring-ws imports your making

    <dependency>
        <groupId>org.springframework.ws</groupId>
        <artifactId>spring-ws-core</artifactId>
        <version>2.0.2.RELEASE</version>
    </dependency>

I am using version 2.0.3.RELEASE. Everything else is exactly the same and i dont have any other spring-ws imports. – ziggy Jul 14 '12 at 12:58
what is your MethodEndpointAdapter that you have configured? i.e. org.springframework.ws.server.endpoint.adapter.DefaultMethodEndpointAdapter. also if you set it at trace you will see the `org.springframework.ws.server.endpoint.adapter.AbstractMethodEndpointAdapter.supports(O bject endpoint)` method being called which decides which adapter will handle that method type. your MethodEndpointAdapter will need to have the MessageContextMethodArgumentResolver added as one of the methodArgumentResolvers. – Shaun Stone Jul 16 '12 at 18:21
(the DefaultMethodEndpointAdapter has this configured by default) – Shaun Stone Jul 16 '12 at 18:37
Thanks Shaun i have now sorted it. The problem was because the saajMessageFactory was not being Autowired correctly. – ziggy Jul 17 '12 at 08:28
