Blackberry 10 cascades ajax call from javascript always executing error function

Question

Hi i am executing an ajax call from javascript in BB10 cascades using webview as below

$.ajax({
    url: internalserverip,
    type: "POST",
    cache: false,
    data: pjsonstring,
    dataType: 'json',
    success: function(json) {
    },
    error: function (xhr, statusText, throwError) {
        alert(JSON.stringify(xhr)); 
            // alerts {"readyState":4,"status":404,"statusText":"error"}
        alert(statusText); // alerts error
        alert(throwError); // alerts null
    },
    async: false
});

It always goes to error function, and alerts the same.

Does the request reach the server? What do the server logs say? — RoToRa, Oct 28 '13 at 11:04
Request has reached server and processed accordingly. But ajax call is unable to get the response sent by server and goes in error block. — sanj15041, Oct 29 '13 at 05:23

@Sanj15041: We know that 404 http code means the content are not found!

You are getting this error maybe because your internalserverip url is not addressing to a valid content on your server Or the server returns 404 error according to the data you are sending as parameters

What to do?

Well:

Please verify if your internalserverip url is being spelled correctly by alerting it(look code bellow)
Check if your server is configured to receive/process POST requests on that url
Navigate to your internalserverip url with the same data (pjsonstring) within the same directory, and check if the result! Maybe it returns 404 too!
be sure your url (internalserverip) returns jsonEncoded data
Paste Your Server Side Code here : So, We'd be able to understand what is not working

Alert your error in case of error to check if it is what you wish

 $.ajax({
    url: internalserverip,
    type: "POST",
    cache: false,
    data: pjsonstring,
    dataType: 'json',
    success: function(json) {
},
error: function (xhr, statusText, throwError) {
    alert("url: "+internalserverip+"\n Parameters: "+pjsonstring+"\n returns : "+JSON.stringify(xhr)); 
    alert(statusText); // alerts error
    alert(throwError); // alerts null
},
async: false
});

In fine: This is not the cause but you don't need to say {cache:false}, because post requests data are never cached!

Good luck
