Lets say i have a Proxy to an object, can I somehow get access to the object via reflection or other technique ?

By proxy i mean the java class(technology) when you have a remote object and you can use it remotely via a proxy classMarek Szanyi– Marek Szanyi2010-09-10 12:43:42 +00:00Commented Sep 10, 2010 at 12:43

No, as a Proxy is not even itself a "true" object. From the javadoc, you can see that the only object you can easily access is the invocation handler. Once this handler is reached, it's a matter of implementation :
- you may encounter n invocation handler that keeps a reference to proxied object (as an example for kind of a decorator)
- but you can also have no other reference (as an example, when implementing the Null object pattern using proxy).

What do you mean by "Proxy to an object"? If you mean the invocation handler of a java.lang.reflect.Proxy instance:
InvocationHandler handler = Proxy.getInvocationHandler(proxy);

If you have a proxy to an object you can use the proxy to access the object.
proxy - An interface for a service, especially for one that is remote, resource-intensive, or otherwise difficult to use directly. (wiktionary)
