Hi..
I'm connecting to am Amazon EC2 instance and running the sample code, I'm getting this exception when I try to instantiate a Client from a JVM behind firewall/ proxy. When I run the same code from an open internet connection then I have no issues!
Is there some configuration/ setting/ code I need to implement to make sure my connection is okay through an HTTP Proxy. Is there an option to disable the callback ( from server to client ) and maybe use polling instead.
Thanks
Amr
