no suitable HttpMessageConverter found for response type [com.src.model.UserDTO] and content type [text/html;charset=UTF-8]

Question

first of all, i've already read all questions related with this topic in stackoverflow, but i can't find the solution. I have been working on this for days.

I have this restFull web app built with spring mvc. When i try to retrieve a User i get this error:

org.springframework.web.client.RestClientException: Could not extract response: no suitable HttpMessageConverter found for response type [com.src.model.UserDTO] and content  type [text/html;charset=UTF-8]

org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:882)

The request never reach the server, so the problem isn't the response content-type, because there is no response. So i am loss there. I show here my classes and configs, if some info is missed, please let me know, and i will update the question. Thanks!

Client controller:

@Controller
public class HomeController extends GenericAbstractController{

@RequestMapping(value = "/home", method = RequestMethod.GET)
public String getHome(HttpServletRequest request, Model model) {
    Principal userPrincipal = request.getUserPrincipal();

    List<MediaType> acceptableMediaTypes = new ArrayList<MediaType>();
    acceptableMediaTypes.add(MediaType.APPLICATION_XML);

    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_XML);
    headers.setAccept(acceptableMediaTypes);
    HttpEntity<UserDTO> entity = new HttpEntity<UserDTO>(headers);

    ResponseEntity<UserDTO> result = restTemplate.exchange("http://localhost:8080/rideon/users/{id}", 
            HttpMethod.GET, entity, UserDTO.class, userPrincipal.getName());

    model.addAttribute("user", result.getBody());


    return "home";
}

Server controller:

@Controller
public class UsersController {

private static final Logger LOGGER = LoggerFactory.getLogger(UsersController.class);
@Autowired
private UserService userService;

@RequestMapping(value = "users/{id}", method = RequestMethod.GET, headers = "Accept=application/xml")
@ResponseBody
public UserDTO getUser(@PathVariable("id") String id) {
    return userService.getUserById(id);
}

User:

@XmlRootElement
@Entity(name = "users")
public class UserDTO implements Serializable {

@Id
private String email;
private String password;
private String name;



public String getPassword() {
    return password;
}

public void setPassword(String password) {
    this.password = password;
}

public String getEmail() {
    return email;
}

public void setEmail(String email) {
    this.email = email;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}
}

Answer 1

Ok I finally found the problem. The response is actually an html error page generated by a wrong security configuration. Indeed the above code seems to be ok. Thanks!
