rest template returns 500 internal server error exception

I’m making an app and trying to get json written on the web page. So, I can see this page in browser: it contains only json.

But when I start a request with the RestTemplate it returns ma only 500 internal server error.

My caode is very simple:

    RestTemplate restTemplate = new RestTemplate();
    HttpHeaders requestHeaders = new HttpHeaders();    
    requestHeaders.setContentType(MediaType.APPLICATION_JSON);
    HttpEntity<?> requestEntity = new HttpEntity<>(requestHeaders);
    ResponseEntity<MyClass[]> responseEntity =     restTemplate.exchange(url, HttpMethod.GET, requestEntity, MyClass[].class);

I cannot understand what is wrong: I have an access, it is simple, I’m not authentificated and I don’t need id. Why an error?

Answer

The 500 Internal Server Error means something has gone wrong on the server side… You should check your URL, parameter, cookies, etc… (in firebug by example)

I test your code and i got a 200 status on a valid URL.
