Thanks you for the answer. My bad i should be more specific.
The link describes how to use the invoker via a "classic" http request. Pretty clear.
The Liferay.Service method though takes 3 arguments. The service "relative url", the data as JSON and a callback function. In other words, it seems to me like you can only invoke ONE service per call (dunno about nested calls, haven't tried). So my question is: Does the javascript "Liferay.Service(...)" function support batch calls and how, cause it isn't clear to me whether this is possible or not?
