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

Question

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.

Answer 1

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.
