Hi All,
This is my first exposure and hello world example with CXF.
I can successfully call web service that is returning string but when I try to
return my simple DTO, I am getting following exception at run time.

Here is my sample code , please have a look and let me know wat I am doin
gwrong.
=============================================================
Service Interface
@WebService
@SOAPBinding(style = Style.DOCUMENT, use = Use.LITERAL)
public interface IService1 {
@WebMethod(operationName="getData")
@ResponseWrapper(targetNamespace="http://cxftest1.cp.vmware.com/types",
className="com.vmware.cp.cxftest.dto.SampleDTO")
public SampleDTO getSampleDTO() ;
}
================================================
Service Class
@WebService(endpointInterface = "com.vmware.cp.cxftest1.IService1",
serviceName = "Service1")
public class Service1 implements IService1 {
private Manager mgr = new Manager();
public SampleDTO getSampleDTO() {
return new SampleDTO("XXXX" , 34) ;
}
}
================================================
DTO
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "SampleDTOInfo", propOrder = {"name","age"})
public class SampleDTO implements Serializable {
public SampleDTO(String name , int age) {
this.name = name;
this.age = age;
}
@XmlElement(name = "name")
public String name;
@XmlElement(name = "age")
public int age;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
}
==========================================================
Styarting Service and Creating Client
public class Service1Test extends TestCase {
public void testApp() throws Exception{
String address = "http://localhost:9000/service1";;
Service1 implementor = new Service1();
Endpoint myEndpoint = Endpoint.publish(address, implementor);
JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
factory.setAddress("http://localhost:9000/service1";);
factory.setServiceClass(IService1.class);
IService1 client = (IService1) factory.create();
client.getSampleDTO();
myEndpoint.stop();
}
}
=========================================================
When I started the service and accessed the http://localhost:9000/service1?wsdl
then I got the wsdl which I have attached with this email. I do not see the
definition of my DTO in it.
