can't access C# method using jquery

I am trying to call a C# method from java script ,I am new to web development and after a bit of searching decided on using jquery to do the same,the way I try to call the method is:

$.ajax({
          type: "POST",
          url: "Default.aspx/IncrementJ",
          data: "{}",
          contentType: "application/json; charset=utf-8",
          dataType: "json",
          success: function(msg) {
            alert("success!")
          }
        });

here IncrementJ is my function name defined in C# which I want to call.here is the definition:

 [WebMethod]
    public static  void IncrementJ()
    {

        try
        {
            j++;
        }
        catch (Exception ex)
        {
            throw ex;
        }
    }

when I run my program web console throws an error "cannot locate resource incrementJ";please tell me where I am going wrong,

Thanks .

Given your comments that the error status 404 (Not Found), can infer that the error is on behalf of the calling script:

"Http Response Codes for Dummies"

50x: we messed up. 
40x: you messed up. 
30x: ask that dude over there. 
20x: cool.

So, given that the script cannot find the webmethod, I think its fair to deduce that it is looking in the wrong location. Try putting a relative path when referencing Default.aspx/IncrementJ.

One thing I see is you need to remove the quotes around the data object .. it should be an empty JS object e.g {} not "{}"
