Spring RESTful Client: Root Tag Exception

Question

I am trying to parse the result from a RESTFull call using RestTemplate after this example http://thekspace.com/home/component/content/article/57-restful-clients-in-spring-3.html

The XML response looks something like this:

<brands>
    <brand>
        <nodeRef>1111111</nodeRef>
        <name>Test</name>
    </brand>
</brands>

First, I configured my application-context.xml as follows:

<?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">

    <bean id="restTemplate" class="org.springframework.web.client.RestTemplate">
        <property name="messageConverters">
            <list>
                <bean id="messageConverter" class="org.springframework.http.converter.xml.MarshallingHttpMessageConverter">
                    <property name="marshaller" ref="xstreamMarshaller" />
                    <property name="unmarshaller" ref="xstreamMarshaller" />
                </bean>
            </list>
        </property>
    </bean>

    <bean id="xstreamMarshaller" class="org.springframework.oxm.xstream.XStreamMarshaller">
        <property name="aliases">
            <props>
                <prop key="brand">com.kipcast.dataModel.drugs.bean.BrandViewList</prop>
            </props>
        </property>
    </bean>


</beans>

The com.kipcast.dataModel.drugs.bean.BrandViewList class is a bean with the definition of @XStreamAlias ​​("brand").

Here is how I do the rest:

ApplicationContext applicationContext = new ClassPathXmlApplicationContext("application-context.xml", WebscriptCaller.class); 
RestTemplate restTemplate = applicationContext.getBean("restTemplate", RestTemplate.class);     

String url = "http://localhost:8081/alfresco/service/search/brand.xml?q={keyword}&alf_ticket={ticket}"; 
List<BrandViewList> results = (List<BrandViewList>) restTemplate.getForObject(url, List.class, params);

WebscriptCaller.class is the class from which I execute these instructions.

When I try to execute this, getForObject () fails, and I get this exception:

XStream unmarshalling exception; nested exception is com.thoughtworks.xstream.mapper.CannotResolveClassException: brands

My question is: how can I fix this? Why am I getting such an exception? How can I tell him to skip the root tag?
