@PayloadRoot value when using Objects and not schema xml

Question

I'm using Objects as messages from client to service server. How should the endpoint be configured so that the service would be found? @PayloadRoot seems unfitting here because i don't use xml schema but Objects annotated with @XmlRootElement (i.e. Street)

my code:

the spring-ws-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns:context="http://www.springframework.org/schema/context"
   xmlns:sws="http://www.springframework.org/schema/web-services"
   xmlns:oxm="http://www.springframework.org/schema/oxm"
   xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd

<sws:dynamic-wsdl id="test" portTypeName="TestCase" locationUri="/testService/"
                  targetNamespace="http://www.example.org/schemasDef/test/definitions">
    <sws:xsd location="/WEB-INF/schemasDef/test.xsd"/>
</sws:dynamic-wsdl>

<bean id="springWSClient" class="com.coral.project.endpoints.SpringWSClient">
    <property name="defaultUri" value="http://localhost:8080/parking/springServices/testService/"/>
    <property name="marshaller" ref="marshaller" />
    <property name="unmarshaller" ref="marshaller" />
</bean>

<oxm:jaxb2-marshaller id="marshaller">
    <oxm:class-to-be-bound name="com.coral.project.entity.Street"/>
</oxm:jaxb2-marshaller>
</beans>

the client:

public class SpringWSClient extends WebServiceGatewaySupport {

public void getSum() throws SOAPException, IOException, TransformerException {
    StreetDao streetDao = SpringUtils.getBean(StreetDao.class);
    Street street = streetDao.findById(1);

    getWebServiceTemplate().marshalSendAndReceive(street);

}
}

the endpoint:

@Endpoint
public class SpringWsEndpoint {

@Inject
private SpringWebService springWebService;

@PayloadRoot(localPart = "street", namespace = "http://blahblah")
@ResponsePayload
public Element handleTestRequest(@RequestPayload SAXSource testRequest) throws Exception {

    String fisrt = firstNum.valueOf(testRequest);
    String second = secondNum.valueOf(testRequest);

    String sum = springWebService.sum(Integer.parseInt(fisrt), Integer.parseInt(second)).toString();

    Element responseElement = new Element("TestRequest");
    Element sumElement = new Element("sum");
    sumElement.setText(sum);
    responseElement.setContent(sumElement);

    return responseElement;
}

}

Found out how to do it. Had to make several fixes. Most importantly @XmlRootElement name and namespace attributes are required in my case. So the working code is:

test.xsd

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" 
    xmlns:test="http://www.example.org/schemasDef/test/schemas" 
    elementFormDefault="qualified"
    targetNamespace="http://www.example.org/schemasDef/test/schemas">

    <xs:element name="TestRequest">
        <xs:complexType>
            <xs:all>
                <xs:element name="firstNum" type="xs:integer" />
                <xs:element name="secondNum" type="xs:integer" />
                <xs:element name="sum" type="xs:integer" />
            </xs:all>
        </xs:complexType>
    </xs:element>

</xs:schema>

TestRequest.java

package com.coral.project.entity;

import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name="TestRequest",namespace="http://www.example.org/schemasDef/test/schemas")
public class TestRequest {

private Integer firstNum;
private Integer secondNum;
private Integer sum;

public Integer getFirstNum() {
    return firstNum;
}
public void setFirstNum(Integer firstNum) {
    this.firstNum = firstNum;
}
public Integer getSecondNum() {
    return secondNum;
}
public void setSecondNum(Integer secondNum) {
    this.secondNum = secondNum;
}
public Integer getSum() {
    return sum;
}
public void setSum(Integer sum) {
    this.sum = sum;
}

}
