The javadoc for JsonpRequestBuilder starts with: """The server will receive a request including a callback url parameter, which should be used to return the response as following: <callback>(<json>); where <callback> is the url parameter (see setCallbackParam (String)),""" It's clear to me that the URL will contain a query string with a parameter like "callback=fnName" (where 'callback' is the value you passed to setCallbackParam, and 'fnName' is the <callback>, i.e. the function name to "call"). It even comes with an example of calling a GData API (with a link to the GData API documentation that explains what "?alt=json-in-script" means) Maybe you should first read some doc about JSON-P, such as http://en.wikipedia.org/wiki/JSON#JSONP -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
