I am implementing a Web Service using Spring WS 2.x using an existing XSD which cannot be changed. Following is my Endpoint method :

Code:
private static final String NAMESPACE_URI = "http://www.xyz.com/cfr/statusrequest";

@PayloadRoot(namespace = NAMESPACE_URI, localPart = "UpdateStatusRequest")
	@ResponsePayload
	public UpdateStatusResponse handleUpdateStatusRequest(@RequestPayload UpdateStatusRequest updateStatusRequest) {
		System.out.println(updateStatusRequest.getStCo());
		
		String statusCode = updateStatusService.updateStatus(updateStatusRequest.getUNa(), updateStatusRequest.getStCo(), updateStatusRequest.getInID().longValue());
		
		UpdateStatusResponse updateStatusResponse = new UpdateStatusResponse()
		updateStatusResponse.setErC("Sample Error Code");
		updateStatusResponse.setReT(statusCode) ;
		
		return updateStatusResponse;
	}
We are using JAXB marshaller to marshal & unmarshall configured as follows :

Code:
<oxm:jaxb2-marshaller id="marshaller" contextPath="com.xyz.cfr.ws.vo"></oxm:jaxb2-marshaller>
When call the method using the SOAP UI gives following error :

No adapter for endpoint [public com.xyz.cfr.ws.vo.UpdateStatusResponse com.xyz.cfr.ws.endpoint.UpdateStatusEndpoint.handl eUpdateStatusRequest(com.xyz.cfr.ws.vo.UpdateStatu sRequest)]: Is your endpoint annotated with @Endpoint, or does it implement a supported interface like MessageHandler or PayloadEndpoint?


I have tried to remove the return object "UpdateStatusResponse" and it works fine, which makes me feel there is a problem with the unmarshalling of response.

The XSD for the UpdateStatusResponse is as follows:

Code:
<?xml version="1.0" encoding="UTF-8" ?>
<schema xmlns="http://www.w3.org/2001/XMLSchema" xmlns:xsd="http://www.w3.org/2001/XMLSchema"

     elementFormDefault="qualified">
    <annotation/>
    <element name="UpdateStatusResponse" type="sres:UpdateStatusResponse">
        <annotation>

                        <enumeration value="F"/>
                    </restriction>
                </simpleType>
            </element>
            <element name="ErC" type="string">

                </annotation>
            </element>
        </sequence>
    </complexType>
</schema>
