Although GWT obfuscates the produced javascript code renaming methods,
classes, etc, it is possible to use a GWT method from javascript if
you export it storing a reference in the window object:
private native void exportMyMethod() /*-{
$wnd.showAlert = function(name) {
return [email protected]::showAlert(Ljava/lang/String;)
(message);
};
}-*/;
Take a look to this article I wrote time ago:
