how to get hold of the interfaces of java.lang.reflect.Proxy object?

[szczepiq]

Let's say I have a proxy object. I want to know what's the interface
this proxy object was created with.

I know that I can check whether class is a dynamic proxy:

Proxy.isProxyClass(proxyObject.getClass())

But I want something like that:

Proxy.getInterfaces(proxyObject)

How can I do that? Is there a library that can help me? Or am I
missing something and this is very easy (yoopie!) or impossible
(errr.... let's get back to Ruby).

Thanks a bunch for any help!

Class[] interfaces = proxyObject.getClass().getInterfaces();

You mean the interfaces, instead of the interface (?)

Proxy.isProxyClass(proxyObject.getClass())

Class[] interfaces = proxyObject.getClass().getInterfaces();
should do the trick.
