You're almost done :-)
You can't use
@com.mantra.draw2d.Home.client:: checkLogin()()
in you handwritten javascript.
this notation can only be used from JSNI methods.
but as you did in your class, you can exposes these methods :
private static native void checkLogin(Home x)/*-{
$wnd.checkLogin = function(){
x...@com.mantra.draw2d.home.
>
> client.Home::UserLogin()();
> };
In you HTML, do :
function cheLogin(){
alert("GWT Call");
checkLogin()
>
>
> alert("GWT Call");
> }
This should work.
