RestClientException Could not extract response spring mvc - spring

Question

i'm trying to connect via the restTemplate to the server side in order to retrieve xml's. But i'm taking an RestClientException and this message:"Could not extract response: no suitable HttpMessageConverter found for response type [frontend.model.Registration] and content type [application/xml]"
In the dispatcher-servlet i write this:
<bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
<property name="mediaTypes">
<map>
<entry key="xml" value="application/xml"/>
<entry key="atom" value="application/atom+xml"/>
<entry key="html" value="text/html"/>
</map>
</property>
<property name="viewResolvers">
<list>
<bean class="org.springframework.web.servlet.view.BeanNameViewResolver"/>
</list>
</property>
And afterwards i add this:
<bean class="org.springframework.http.converter.xml.SourceHttpMessageConverter"/>
Also the exception appears at this line:3
ResponseEntity<Registration> result = restTemplate.exchange("http://www.../ckp/user/{id}",
HttpMethod.GET, entity, Registration.class, id);
I can't solve the problem days now..i'm thinking to add ViewResoler and MessageConverter by i don't know which resolvers and which converters. Can anyone propose something to try?
Should i add something on disptcher servlet?should i add a library?
My model classes are pojo's contains jaxb annotations.

You need to add the xml message converter bean to the RestTemplate bean definition. This is what I use:
<bean id="restTemplate" class="org.springframework.web.client.RestTemplate">
<property name="messageConverters">
<list>
<bean class="org.springframework.http.converter.xml.SourceHttpMessageConverter"/>
<bean class="org.springframework.http.converter.FormHttpMessageConverter"/>
<bean class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"/>
</list>
</property>
</bean>
Don't forget to inject the restTemplate bean into your class (via xml or annotation).
EDIT: In your class where you call RestTemplate, add a field like this:
#Inject
private RestTemplate restTemplate;
