Phonegap iOS Ajax Call

[Federico Fricke]

HI,

I having an issue consuming  a RESTful service build in Java.

When I create an Ajax Call to a service I don't get any response (nor failure, nor success).

I have test this issue using jQuery and directly using XMLHttpRequest and I have the same behaviour.

$.ajax({
       type: "GET",
       url: appBaseURL + "service" + cookie,
       contentType: "application/json; charset=utf-8",
       dataType: "json",
       timeout: 10000,
       }).
done(function(){console.log("All done");}).
fail(function(){console.log("It fail");}).
always(function(){console.log("Complete");});


var xhrManual = new XMLHttpRequest();
xhrManual.onreadystatechange = function()
{
    console.log("Ready State: " + xhrManual.readyState);
    if ( xhrManual.readyState == 4) {
        console.log("Ready State 4");
    }
}
xhrManual.open("GET",appBaseURL + "service" + cookie,true);
xhrManual.setRequestHeader('Content-type', 'application/json; charset=utf-8');
xhrManual.send();

I have tried the following workaround without any luck.

Tested it using the latest version of phonegap (cordova.js 3.0.0-0-ge670de9 and 2.9.0-0-g83dc4bd)

Used jquery 1.10 and 1.11 (I know now that this has nothing to do...)

I believe the issue is related with the returned data. But it doesn't have to do with null; sometimes it fails when the structure is more complex.

If I return this, it doesn't work

[
{"field1":"value1","field2":null},
{"field1":"value1","field2":null},
{"field1":"value1","field2":null}
]

If I return the following it works!

[
{"field1":"value1","field2":""},
{"field1":"value1","field2":""},
{"field1":"value1","field2":""}
]

I have captured the network request using safari web inspector and I get a status 200.

I have tested this in browsers and in Android and it works ok!

Any idea?

Just to follow up...

I tried to do the request sync using the XMLHttpRequest and I get the following error:

XMLHttpRequest Exception 101: A network error occurred in synchronous requests.

If I saw the error in Android or in the browser I will immediately point out to the server... but right now I believe that's maybe a combination of between those two.

Well i resolve the issue.

The issue was in Jersey.

I will submit another post with the final and cleanest solution.

Right now it's working using:

response.flushBuffer();
