Again, thanks for your tip. It got me going in the right direction.
For the record, my solution was to create (as Thomas suggested) a
"peer" callback object that extends JavaScriptObject that defined the
same method signature. So if my callback object was defined like
this:
public interface MyCallback {
void onSuccess(Object result);
}
I would defined the "peer" JSO like this:
public class MyCallbackJso extends JavaScriptObject {
protected MyCallbackJso() {
}
public final native void onSuccess(Object result) /*-{
this.onSuccess(result);
}-*/;
public static native MyCallbackJso wrap(MyCallback delegate) /*-{
var wrapped = { "delegate" : delegate };
wrapped.onSuccess = function(entity) {
this.delega...@mycallback::onSuccess(Ljava/lang/Object;)
(entity);
}
return wrapped;
}-*/;
}
And then wrap my calls to the service:
service.doSomethingAsync(MyCallbackJso.wrap(new MyCallback() {
public void onSuccess(Object result) {
//handle the result.
}
}));
