What I mean is illustrated by this example:
import java.lang.reflect.InvocationHandler;
import java.lang.reflect.Method;
import java.lang.reflect.Proxy;
public class Test
{
public static void main(String[] args)
{
final ITest t = new Test2();
ITest tp =
(ITest)Proxy.newProxyInstance(ITest.class.getClassLoader(),
new Class[] { ITest.class }, new InvocationHandler()
{
public Object invoke(Object proxy, Method method,
Object[] args)
throws Throwable
{
System.err.println(method + " of page called!");
return method.invoke(t, args);
}
});
tp.foo();
}
private static interface ITest
{
void foo();
}
private static class Test2 extends Test implements ITest
{
}
public void foo()
{
System.out.println("Hi there");
}
}

Anyway, Peter to get back to your original problem. You want to be
able to create proxies. You can do that if you want. Even though the
Page class is backed by an interface in it's core, Page (or actually,
you should use WebPage) is designed for inheritance, so you have to
provide your own subclasses for concrete pages anyway. And what is to
stop you from simply extracting the interface you'd like to proxy and
let your (base) class implement that interface?
