I am trying to use the remote option in jQuery to perform a server side validation. I am able to get the client side validation correctly. 

I want to call serverside method checkRoiRequired which returns JSON true or false based on 3 parameters: analysthours, engineerhours and projectid. I have gone through numerous posts; but nothing has worked yet.

When the form is submitted, the validation never occurs; there is no log found that the method is called. Please help me out with the following. 

2. $(document).ready(function() {
3. 
   
5. // validating the form
6. $("#command").validate({
8.   rules:{
9. "projHeader.roiAttachmentLink": {
10. remote:{
11.                  url: "../project/checkRoiRequired.do" ,
12.   data: {
13. revAnalystHour: function() { return $("#reAnalystHours").val(); },
14. revEngineerHour: function() { return $("#reEngineerHours").val(); },
15. projectId: function() { return $("#projectId").val(); }
16. }
17. }
18.  }
19.    },
20. messages:{
21.   "projHeader.roiAttachmentLink": {
22.              remote:"ROI attachment link is required"
23.   }
24.     },
25. errorElement: "div",
26.                         wrapper: "div",  // a wrapper around the error message
27.                   errorPlacement: function(error, element) {
28.            offset = element.offset();
29.            error.insertBefore(element)
30.            error.addClass('message');  // add a class to the wrapper
31.            error.css('position', 'absolute');
32.            error.css('left', offset.left + element.outerWidth());
33.            error.css('top', offset.top);
34.      }
35. });  
36. });

When I use the required : true option in above rules, it works fine.
