Get the session ID on the client side

[Bryan Kearney]

I have a client which is set up to use sessions using the following code:
((BindingProvider) 
proxy).getRequestContext().put(BindingProvider.SESSION_MAINTAIN_PROPERTY, 
true);

Is there any way to get the session ID / cookie back from the provider? 
I looked at the response conext and it is not in there?

Thanks!
