Just to add a bit more in case that wasn't clear:
If you have a class 'Class1' that you cannot modify with a static field:
public final Class1 {
public static int counter = 55;
}
You can make a new class, ie. 'Class1Exposer'
public class Class1Exposer {
public static int getClass1Counter() {
return Class1.counter;
}
public static native void exportStaticMethod() /*-{
$wnd.counter =
$entry(@mypackage.Class1Exposer::getClass1Counter());
}-*/;
}
