JAXBElement with REST: Could not find acceptable representation

[Merguez]

Hi all,

I try to return some JAXBElement in a REST controller.
When i call my REST endpoint, i have an exception that say : "org.springframework.web.HttpMediaTypeNotAcceptable Exception: Could not find acceptable representation".

The return type "JAXBElement<OrgListType>" and the "ObjectFactory" come from a tierce librairy.

My REST endpoint is the following:

	@Autowired
	private LoginService loginService;	

	@RequestMapping(value = "/api/v1.0/login", method = RequestMethod.POST)
	public @ResponseBody JAXBElement<OrgListType> login(HttpServletResponse response) throws Exception {
		
		ObjectFactory objectFactory = new ObjectFactory();
		return objectFactory.createOrgList(loginService.login());
	}

My Spring REST configuration:

	<context:component-scan base-package="xxx.interaction.api" use-default-filters="false">
		<context:include-filter expression="org.springframework.stereotype.Controller" type="annotation" />
	</context:component-scan>

	<mvc:annotation-driven />

	<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
		<property name="messageConverters">
			<util:list id="beanList">
				<ref bean="stringHttpMessageConverter" />
				<ref bean="marshallingHttpMessageConverter" />
			</util:list>
		</property>
	</bean>

	<bean id="stringHttpMessageConverter" class="org.springframework.http.converter.StringHttpMessageConverter" />

	<bean id="marshallingHttpMessageConverter" class="org.springframework.http.converter.xml.MarshallingHttpMessageConverter">
		<property name="marshaller" ref="jaxb2-marshaller" />
		<property name="unmarshaller" ref="jaxb2-marshaller" />
	</bean>

	<oxm:jaxb2-marshaller id="jaxb2-marshaller" contextPath="com.vmware.vcloud.api.rest.schema"/>

The package com.vmware.vcloud.api.rest.schema contain the OrgListType.

I don't understand why Jaxb2 can't marshal the JAXBElement<OrgListType>.
