I could solve my issue with RC.'s help. I'll post the answer to help other people.

The problem was that Accept header is automatically set to APPLICATION/JSON so I had to change the way to invoke the service in order to provide the Accept header I want.

I changed this:

String response = getRestTemplate().getForObject(url, String.class);

To this in order to make the application work:

// Set XML content type explicitly to force response in XML (If not spring gets response in JSON)
HttpHeaders headers = new HttpHeaders();
headers.setAccept(Arrays.asList(MediaType.APPLICATION_XML));
HttpEntity entity = new HttpEntity("parameters", headers);

ResponseEntity response = getRestTemplate().exchange(url, HttpMethod.GET, entity, String.class);
String responseBody = response.getBody();
