Description

When you call the HttpClient on Rest API on url that return you an error, the HttpClient failed to give you the error stream:

callResult = restClient.getStream();

If the flow is an error you have HttpClient:534

in = con.getInputStream();

return a FileNotFoundException

To solve this I catch the error and restart the connexion like this

if ((con instanceof HttpURLConnection)) {
    try {
        in = ((HttpURLConnection) con).getErrorStream();
    } catch (Exception ioerror) {
        throw new HttpClientException("IO Error processing request", ioerror);
    }
    return in;
}

With this the inputStream contains the error message and we can use it for end user return
