Getting the error: "No adapter for endpoint" when triggering SOAP Request

+1 vote
10,095 views

I am using Springs 3.0 with JAXB.. I am trying to retrieve a list of IDs through Webservice.. The WSDL is published properly.. But when I hit a SOAP request, I get a response which says:

No adapter for endpoint [public wsi.deviceprofile.GetDeviceProfileIDsResponse wsi.deviceprofile.DeviceProfileEndPoint.getDeviceProfileIDList()]: Is your endpoint annotated with @Endpoint, or does it implement a supported interface like MessageHandler or PayloadEndpoint?

My class is annotated with @EndPoint:

@Endpoint
public class DeviceProfileEndPoint implements DeviceProfileConstants {

    @Autowired
    private DeviceProfileManager deviceProfileManager;

    @PayloadRoot(localPart="GetDeviceProfileIDsRequest", namespace=NAMESPACE)
    @ResponsePayload
    public GetDeviceProfileIDsResponse getDeviceProfileIDList(){
        ObjectFactory factory = new ObjectFactory();
        GetDeviceProfileIDsResponse response = factory.createGetDeviceProfileIDsResponse();

        List<DeviceProfileWebVO> deviceProfiles = deviceProfileManager.getAllDeviceProfileWebVO();
        for(DeviceProfileWebVO deviceProfile : deviceProfiles)
            response.id.add(BigInteger.valueOf(deviceProfile.getDeviceId()));       

        return response;
    }
}

Few websites say this might be a problem with the XSD structure and have suggested few guidelines (like, defining the request/response elements inline rather than a reference).. I have ensured that those have been taken care of. However, The problem remains. Here is my XSD:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="unqualified" targetNamespace="http://www.hp.com/schema/m2m/" xmlns:tns="http://www.hp.com/schema/m2m/">
    <!-- 
        Get list of all the Device Profile IDs
    -->
    <xs:element name="GetDeviceProfileIDsRequest">  
    </xs:element>
    <xs:element name="GetDeviceProfileIDsResponse">
        <xs:complexType>
            <xs:sequence minOccurs="0" maxOccurs="unbounded">
                <xs:element name="id" type="xs:integer"/>
            </xs:sequence>
        </xs:complexType>
    </xs:element>

</xs:schema>

Does anyone know any other possible reasons? Let me know if you need more details.

Yes Ranjeeth this problem is related with XSD, you need to correct your XSD. Let me have a look into your problem.
check the following link http://forum.springsource.org/archive/index.php/t-46439.html specially the second problem.

I figured out the answer. It was more of a Springs configuration rather than XSD issue.

In the springs-ws-servlet.xml, I had to mention the "contextPath" for the marshaller which I had missed out before. "contextPath" property would refer to the package where the JAXB generated classes(request/response) are present.

<bean id="marshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
    <property name="contextPath" value="wsi.deviceprofile"/>
    <property name="schema" value="/WEB-INF/schema/DevProfMgmtService.xsd" />
</bean>

Thanks Salil and Sudhee for your inputs.

Can anybody point me to create and test an async web service using ws-addressing? The message exchange I want to implement is this:
1. Client sends a SOAP request message to the Server
2. Server sends an HTTP 202 Accepted to the Client
3. Server sends a SOAP response message to the Client
4. Client sends an HTTP 202 Accepted to the Server

I am using Springs WS 2.0.5. The Springs documentation mentions the configuration required to make configurations on server side and client side to access a web service asynchronously. But I am not able to arrive at a client to test if the server implementation is proper. I tried using SOAP UI to trigger request with relevant WS-A headers set. However, I receive a "synchronous" response.

Should the client also implement and expose an Endpoint to receive the response?

I am using Springs 3. I have a method in an Endpoint class which handles the web service request. The method is annotated with @Action to make it asynchronous. The SOAP request header contains some information (like UUID, Reply Address, etc). I need to be able to access these header information from inside this method.

The Spring WS MessageContext as well as the Apache axis MessageContext seems to be empty, so I am not able to use it inside the method to derive the SOAP header.
