unable to load datatable with json data from ajax call

neelma

I have a form, on click of Search , it makes an ajax call to servlet thar returns a JSON respose. (attached json format which is an array of objects). I am trying to load my dataable with the returned data but table is never loaded at all and it shows Loading.. message. The same json works fine when i use an external file and point sAjaxSource to the file.
