Struggling with some issues related to AJAX, specifically when calling a Java REST server that I've developed. While I am relatively new to AJAX, I have put in quite a bit of effort searching for solutions. The problem arises when making a call from a test HTML page within the REST server (running on Jetty). The following function works successfully using .get:
$('#getRVLakeForm').submit(function(e) {
var handle = $('#insertRVLakeHandle').val();
var lakekey = $('#RVLakeKey').val();
var temp = $('#RVLakeTemp').val();
var speed = $('#RVLakeWindspeed').val();
var degrees = $('#RVLakeWindDegrees').val();;
$.get('${pageContext.request.contextPath}/api/recent/lake/' + handle + "/" + temp + "/" + speed + "/" + degrees + "/" + lakekey, function(data) {
alert(data.lake[0].oid);
$('#RMLakeResponse').text("back");
});
The JSON returned by the REST server is as follows:
{"user":[],"lake":[{"oid":"519b9a1a3004f8fa1287502a","type":"Lake","handle":"nightstalker","viewedhandle":"","viewedlaketag":"TXFORK","viewedusername":"","timestamp":1369152026668}]}
While this call successfully executes the REST API and receives the expected JSON response, the issue arises when attempting to make the same call from an HTML/PHP application running under MAMP. The outbound AJAX call works fine—I can debug the Java REST server and see the call coming in, executing as intended and producing JSON to send out. However, the problem lies in the fact that the success function in the AJAX call never gets called (nor does the error function).
urlrecent = "http://localhost:8080/server/api/recent/lake/" + handle + "/" + temp + "/" + speed + "/" + degrees + "/" + lakekey;
$.ajax({
type: "GET",
contentType: "application/json",
dataType: "jsonp",
url: urlrecent,
success: function (data) {
alert("hello there!");
alert(data)
},
error: function () {
alert('failed');
}
});
I even tried using getJSON instead, but no luck so far. In the meantime, I'll continue exploring Stack Overflow and other online resources for a potential solution. I also experimented with setting the datatype to just "json."
Thank you in advance.

Yes, I messed up the contentType, but it didn't seem to have any impact.
