spring ws not finding the adaptor when using annotated endpoints

I am using Java 6 and spring-ws to create a very simple web service which receives 2 parameters in the form of a BusquedaRequest Jaxb object and returns the same object.

The object has been created with xjc compiler and I am using Jaxb2Marshaller as the mashaller and GenericMarshallingMethodEndpointAdapter to convert to incoming xml and out going. I had this working when extending the AbstractMarshallingPayloadEndpoint class but when I switch to using the Endpoint and payload annotations it always fails.

The web service starts up fine but when hitting it with a client I recieve this exception.

java.lang.IllegalStateException: No adapter for endpoint [public package.busqueda.ws.BusquedaRequest package.busqueda.ws.BusquedaEndpoint.getResultas(package.busqueda.ws.BusquedaRequest)]: Does your endpoint implement a supported interface like MessageHandler or PayloadEndpoint?

I have seen response to this question which suggest to compile objects using the xjc compiler which I have done. Also there has been suggestions that the Adaptor hasn't been defined in the spring-ws-servlet.xml, which I have also done. See the spring-ws-servlet.xml defined below:

    <?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
 xmlns:xsi="http://www.w3.org/2001/XMLS开发者_如何学JAVAchema-instance"
 xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">

 <bean id="busquedaEndpoint" class="package.BusquedaEndpoint" />

 <bean class="org.springframework.ws.server.endpoint.adapter.GenericMarshallingMethodEndpointAdapter">
        <constructor-arg ref="marshaller"/>
    </bean>

    <bean id="marshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
        <property name="classesToBeBound">
            <list>
                <value>package.BusquedaRequest</value>
            </list>
        </property>
    </bean>

 <bean id="busqueda"
  class="org.springframework.ws.wsdl.wsdl11.DefaultWsdl11Definition">
  <property name="schema" ref="schema" />
  <property name="portTypeName" value="Busqueda" />
  <property name="locationUri" value="/BusquedaService/" />
 </bean>

 <bean id="schema" class="org.springframework.xml.xsd.SimpleXsdSchema">
  <property name="xsd" value="/WEB-INF/busqueda.xsd" />
 </bean>

 <bean class="org.springframework.ws.server.endpoint.mapping.PayloadRootAnnotationMethodEndpointMapping"/>
</beans>

The class endpoint is as follows:

package package.busqueda.ws;

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

    @Endpoint
public class BusquedaEndpoint {

 @PayloadRoot(localPart = "BusquedaRequest", namespace = "http://busqueda/schemas")
 public BusquedaRequest getResultas( BusquedaRequest aRequest ) {
  return aRequest;
 }

}

The xsd I generated the BusqeudaRequest object is as follows:

     <?xml version="1.0" encoding="UTF-8"?>
     <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
 elementFormDefault="qualified"
 attributeFormDefault="qualified" 
 xmlns="http://busqueda/schemas"
 targetNamespace="http://busqueda/schemas">
 <xs:element name="BusquedaRequest">
  <xs:complexType>
   <xs:all>
    <xs:element name="Consulta" type="xs:string" />
    <xs:element name="Permisos" type="xs:string" />
   </xs:all>
  </xs:complexType>
 </xs:element>
</xs:schema> 

Anyone got any thoughts which extend the suggestions I have already implemented?

When faced with the same problem, I found that adding @RequestPayload and @ResponsePayload annotations to the parameters of the method in the EndPoint implementation would solve the issue.

@whatsthebeef Maybe it's offtopic, or late, but what I see where the problem is, the way you use Marshaller from my point of view stinks.

Why do you use classesToBeBound? If you use XJC & JAXB generating process you really should point 'just' to the package i.e.

<bean id="jaxb2Marshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
    <property name="contextPaths">
        <list>
            <value>my.package.where.the.jaxb-generated.stub-objects.reside</value>
        </list>
    </property>
</bean>

2nd thing is, how should spring context know about your marshaller? I miss using the appropriate Marshaller.

<bean id="endpointAdapter" class="org.springframework.ws.server.endpoint.adapter.MarshallingMethodEndpointAdapter">
    <constructor-arg ref="jaxb2Marshaller"/>
</bean>

That's the way i did it with the current spring-ws package. Btw the stacktrace tells you that the problem is with the *EndpointAdapter. Please let me know if it helped you.
