I am not sure if I understand the question, but let me see if I can answer
it.
The API for GenericEntity<T> has an example of usage. If I had a
List<Widget> which I wanted to return (assuming POJO mapping is enabled), I
would wrap the response back to the caller (client) something like this
@GET
@Produces({MediaType.APPLICATION_JSON})
public Response getWidgets() {
List<Widget> widgets = WidgetDAO.getAllWidgets();
GenericEntity<List<Widget>> ge = new GenericEntity<List<Widget>>(widgets){};
return Response.ok(ge);
}
