Any good AJAX framework for Google App Engine apps? [closed]

Answer 1

try also GQuery for GWT. This is Java code:

public void onModuleLoad() { 
    $("div").css("color", "red").click(new Function() { 
        public void f(Element e) { 
            Window.alert("Hello"); 
            $(e).as(Effects).fadeOut(); 
        } 
    }); 
} 

Being Java code resulting in somewhat expensive compile-time (Java->JavaScript) optimizations and easier refactoring.

Nice, it isn't?
