Both of these methods work fine for me:

$.getJSON('http://site1:8888/myjson.json?format=json&callback=?',
function(data) {
        alert(data.result);
});


$.ajax({
        url: 'http://site1:8888/myjson.json?format=json',
        dataType: 'jsonp',
        success: function(data) {
                alert(data.result);
        }
});
