No adapter for endpoint [ ... ] Does your endpoint implement a supported interface...

[El Turko Mohammed]

This is driving me mad... I Created a project using JaxB the problem is it throws this exception...

No adapter for endpoint [public com.cda.gsp.dto.GetClientesResponse com.cda.gsp.webServices.GspServiceEndpoint.obtener Clientes()]: Does your endpoint implement a supported interface like MessageHandler or PayloadEndpoint?...

Here is the spring-ws-servlet.xml

*and last... the endpoint

package com.cda.gsp.webServices;

import java.util.Collection;

import javax.xml.bind.JAXBElement;

import net.sf.dozer.util.mapping.MapperIF;

import org.springframework.ws.server.endpoint.annotation. Endpoint;
import org.springframework.ws.server.endpoint.annotation. PayloadRoot;

import com.cda.gsp.dto.GetClientesResponse;
import com.cda.gsp.dto.GetProyectoResponse;
import com.cda.gsp.model.Cliente;
import com.cda.gsp.model.Proyecto;
import com.cda.gsp.services.GspService;

@Endpoint
public class GspServiceEndpoint {

private MapperIF mapper;
public GspService service;


@PayloadRoot(localPart = "GetProyectoRequest", namespace = "http://www.example.org/GSPXMLSchema")
public GetProyectoResponse obtenerProyectoPorId(JAXBElement<Integer> idProyecto) {
Proyecto aProyecto = this.service.obtenerProyectoPorId(idProyecto.getVa lue());
return (GetProyectoResponse) mapper.map(aProyecto, GetProyectoResponse.class);
}

@PayloadRoot(localPart = "GetClientesRequest", namespace = "http://www.example.org/GSPXMLSchema")
public GetClientesResponse obtenerClientes() {
Collection<Cliente> clientes = this.service.obtenerClientes();
return (GetClientesResponse) mapper.map(clientes, GetClientesResponse.class);
}

public MapperIF getMapper() {
return mapper;
}

public void setMapper(MapperIF mapper) {
this.mapper = mapper;
}

public GspService getService() {
return service;
}

public void setService(GspService service) {
this.service = service;
}

}

now where is the problem... public GetProyectoResponse obtenerProyectoPorId(JAXBElement<Integer> idProyecto) is working fine and I dont have to declare a JAXBElement for GetProyectoResponse... but when I try to access public GetClientesResponse obtenerClientes() it throws the no adapter exception... can somebody help me...

[Arjen Poutsma]

This is more a JAXB2 issue than a Spring-WS issue, but let's see if I can help you.

The classes generated by JAXB2 from your schema come in two flavors: those that have a @XmlRootElement annotation, which can be used directly as either parameter or response, and those who haven't. Those classes which haven't got this annotation need to be wrapped in a JAXBElement.

Besides the generated classes from your schema, JAXB2 also generates an ObjectFactory class, which clarifies the use of JAXBElement. There are some factory methods is there, which illustrate how you can use the various schema types.

[El Turko Mohammed]

I have found the problem the JAXB endpoint must have a JAXB element as a parameter event if it has no atributtes ( its generated by the plugin from the XSD).
this is the final endpoint

@PayloadRoot(localPart = "GetClientesRequest", namespace = "http://www.example.org/GSPXMLSchema")
public GetClientesResponse obtenerClientes(GetClientesRequest request) {
Collection<Cliente> clientes = this.service.obtenerClientes();
GetClientesResponse clientesResponse = new GetClientesResponse();
for (Cliente cliente : clientes) {
clientesResponse.getCliente().add((com.cda.gsp.dto .Cliente) mapper.map(cliente, com.cda.gsp.dto.Cliente.class));
}

return clientesResponse;
}

thank you for your time

Arjen,

I am having the same problem, but I don't understand your explanation.
I am using JAXB2. The generated class from my xsd is wrapped in @XmlRootElement( (unfortunately on preview of this I keep getting
an error about posting urls to another site, so hand edited the urls out an put in
"url").

Basically, I took the Spring In Action Poker-WS and converted it to my needs. The
real difference is that I am using JAXB2 for the marshalling.

Also, is there any way to see the dynamically generated wsdl?

Thanks for your help this is driving me crazy,
manco

This is the error I am getting, followed by my xxx-servlet.xml file contents
