You have
serverSide : "true",. Do you need server side processing? Take a look at this FAQ to determine if you will need server side processing. If not you should remove that config option. Otherwise your server script will need to follow the protocol described here:https://datatables.net/manual/server-side
I suspect the Web Service you are using won't support this protocol and you will need to disable it. Try removing
serverSide : "true",to see what happens. If that doesn't help then we will need to see a link to your page or a test case to diagnose the problem.https://datatables.net/manual/tech-notes/10#How-to-provide-a-test-case
Or you could generate a debugger image for the developers to look out.

thank you for reply
i set some basic configuration,
but i've done fix the problem,
the problem in json file i have "obj:" title, after i change the title to "data:" it's work
i dont know why but title should be "data:" canot used another text
if u know, can u explain why ??
I just noticed that
columnsinitialisation is within theajax- it isn't supposed to be. Could you your current client-side initialisation code so we can verify again, please.
