custom class mapping in Flash

If I've got a simple bean class defined in an AS2.0 class and a Java class, how does that bean get created on the Flash end after a remoting call?

For instance, in my Flash code I've got

function Result() {
 this.onResult = function(myBean) {
 }
}

var server = gw.getService("com.mysite.Remoting", new Result());


From the logging info it appears my Java class is in fact being serialized back to Flash, I just don't know how to reference it.
