How to configure cxf to use MOXY Jaxb for RESTful

[allam-di]

Hello all,

I would like to use MOXY in order to handle interfaces as input arguments on
my service methods.
First, I tested MOXY data binding with interfaces as it is given in the
following blog:
http://blog.bdoughan.com/2010/07/moxy-jaxb-map-interfaces-to-xml.html

It works oK for me, thus I can serialize and deserialize messages by
declaring a service method with an interface argument, without defining any
implementation classes of this interface.
In order to do a similar think integrated to cxf, I followed the discussion
at this link:
http://cxf.547215.n5.nabble.com/How-to-configure-CXF-to-use-different-JAXBContextFactory-td5281773.html

Here is my ContextResolver Class:
-----------------------------------------

package project;

@Provider
public class MyContextResolver implements ContextResolver<JAXBContext> {
    private JAXBContext jc;

    public MyContextResolver() {
        try {
           
            jc = JAXBContext.newInstance(MyObjectFactory.class);
        } catch(JAXBException e) {
            throw new RuntimeException(e); 
        }
    }
 
    public JAXBContext getContext(Class<?>  type) {
                  try {
                       jc = JAXBContextFactory.createContext(new Class[]
{MyObjectFactory.class}, null);
        
                      return jc;
                  } catch (JAXBException e) {
                      e.printStackTrace();
                  }  
                  return null;
              }
 
}

Here is my ObjectFactory class:
-----------------------------------------
@XmlRegistry
public class MyObjectFactory {

  
    public Customer createCustomer() {
        return createInstance(Customer.class);

    }
    ...
    
  
    private <T> T createInstance(Class<T> anInterface) {
        return (T) Proxy.newProxyInstance(anInterface.getClassLoader(), new
Class[] {anInterface}, new InterfaceInvocationHandler());
    }
  
   private static class InterfaceInvocationHandler implements
InvocationHandler {
  
        private Map<String, Object> values = new HashMap<String, Object>();
  
        public Object invoke(Object proxy, Method method, Object[] args)
throws Throwable {
            String methodName = method.getName();
            if(methodName.startsWith("get")) {
                return values.get(methodName.substring(3));
                
            }   
            else {
                values.put(methodName.substring(3), args[0]);
                return null;
            } 
        }
  
    }
}

Here is my bean.xml file:
-----------------------------------
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans";
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";

        xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://cxf.apache.org/jaxrs
http://cxf.apache.org/schemas/jaxrs.xsd";>
          <import resource="classpath:META-INF/cxf/cxf.xml" />
      <import resource="classpath:META-INF/cxf/cxf-servlet.xml" />
        <jaxrs:server id="test" address="/">
                <jaxrs:serviceBeans>
                        <ref bean="myWebService" />
                </jaxrs:serviceBeans>
               <jaxrs:providers>
                        <ref bean="MOXYProvider" />
              </jaxrs:providers>  
        </jaxrs:server>
        
        <bean id="MOXYProvider" class="project.MyContextResolver" /> 
        <bean id="myWebService" class="project.Service" />
</beans>

Here is a the constructor of my service class:
----------------------------------------------------
public Service(){
        
                ObjectFactory objectFactory = new ObjectFactory();
               Customer c = objectFactory.createCustomer();
               c.setName("defaultName");
               Address address = objectFactory.createAddress();
               address.setCity("defaultAddress");
               address.setStreet("defaultStreet");
               c.setAddress(address);
        
                this.resources.put(c.getName(), s);
                
        }

and here is my GET method:

        @GET
        @Path("/resources/{name}/")
        public Customer getCustomer(@PathParam("name") String name) {
                 return this.resources.get(name);
        }

When I call my service, I get the following error:

Exception in thread "main" Status : 500

Any idea about this error please?
