java - Ajax call to Rest service not successfully calling success function in ajax -

i having ajax difficulties (and newish ajax, have done fair bit of searching) when calling java rest server have written. have test html page running within rest server (using jetty) , use following call -- works 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");             }); 

here json rest server returns:

{"user":[],"lake":[{"oid":"519b9a1a3004f8fa1287502a","type":"lake","handle":"nightstalker","viewedhandle":"","viewedlaketag":"txfork","viewedusername":"","timestamp":1369152026668}]}

this call executes rest api , gets json expected... when attempt call same rest api html/php application, running under mamp -- ajax call works on out bound call -- can debug java rest server , see call come in, , executes designed creating json send out. problem never call success function in ajax call (i not seeing error function called either).

    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 have tried getjson instead..no luck. in mean time continue search stack , web work. have tried datatype of "json" well.

thanks in advance.

yes, munged contenttype, didn't matter.

try in ie8 , set datatype: "html"

urlrecent = "http://localhost:8080/server/api/recent/lake/" + handle + "/" + temp + "/" +  speed + "/" + degrees + "/" + lakekey;      $.ajax({         type: "get",         contenttype: "application/json",         datatype: "html",         url: urlrecent,         success: function (data) {             alert("hello there!");             data = json.parse(data);             alert(data)         },         error: function () {             alert('failed');         }     }); 

if syntex error @ data = json.parse(data) or "hello there" in alert , encoding problem. in case should use response.setcharacterencoding("utf8")
