I am getting a very strange error while the response is correct and I can see the JSON content:

here is the request:

$.ajax({
                    type: "GET",
                    url: urlTwitter,
                    contentType: "application/json",
                    dataType: "jsonp",
                    async: false,
                    success: function (resp, status, xhr) {
                       $("#message").html("STATUS: " + xhr.status + " " + xhr.statusText + "\n" + resp);
                       $("#message").hide();
                       $.each(resp, function() {
                            $.each(this, function(i, tweet) {
                                arrayTweets.push(tweet);
                            });

                        });

                        displayTweets();
                    },
                    error: function(resp, status, xhr){
                        $("#message").html("ERROR: " + xhr.status + " " + xhr.statusText + "\n" + resp.e);
                        $("#message").show();
                    }
                });

Here is the conent in the response:

{"tweet":[{"text":"RT @OSCARHAROTASEND: MUYYY CONTENTO Y MUYYY ORGULLOSO del trabajo d mi hermanito @pablonieto22 en la presentación d su TEAM @CalvoTeam anoc…","user":"Jemurillove"}]}

Anyone has a clue, I've been fighting with this half day.

Appreciate any help.

Thanks,

EDIT:

this is my resource, if it can help. And the Tweet object is annotated with @XmlRootElement:

        List<Tweet> lTweets = new ArrayList<Tweet>();
        boolean status = false;

        Twitter twitter = new TwitterFactory().getInstance();

• are you using <meta http-equiv="content-type" content="text/html; charset=UTF-8" /> in your page? – anurupr Commented Mar 8, 2014 at 9:56
• @anurupr no I am not. – mzereba Commented Mar 8, 2014 at 9:59
• Response you posted clearly means, that request does not runs as JSONP, because we don't see data wrapped in callback. I see you assigned async: false, but JSONP request cannot be synchronous. Try to remove this line and check response. It should be like callback323123123123({ /* data here */ }) – Tommi Commented Mar 8, 2014 at 10:05
• After edit I see you use your own proxy, not direct twitter API call. In this case you need to make JSONP-patible response. See @knolleary answer. – Tommi Commented Mar 8, 2014 at 10:09
• @Tommi removing async gives the same. – mzereba Commented Mar 8, 2014 at 10:14

You are requesting a jsonp response, but the response is plain JSON.

You can either change the request type to 'JSON' - if the request doesn't fall foul of cross-domain restrictions, or change whatever is generating the response to wrap the response as JSONP.

For more information on JSONP, have a look at the jQuery docs

In summary, jQuery automatically adds a callback=? parameter to the url it requests. Your server-side code needs to use the value of that parameter as the name of a javascript function your response should invoke with the JSON passed as an argument.

For example, if callback=helloWorld, your response should be:

helloWorld({"tweet": ... });
