I have created an WCF data service in a new asp.net web application and i want to call this web service from another web application using jquery, but it always returns null.

My jquery call looks like this:

```
$.ajax({
    type: "GET",
    url: "http://localhost:2916/PennyBridge.svc/Member",
    data: "{}",
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    success: function (data) {
   },
    error: function (xhr) {
        alert(xhr.responseText);
    }
});

```

Note that "http://localhost:2916/PennyBridge.svc/Member" works in the browser but since the jquery call is from localhost:3410 i assume its a problem with cross domain.

I have been reading that i should use jsonp for this, but i have a hard time figuring it out.

What do i need to use jsonp? Do i need to configure my WCF data service?
