                 socket.close(); 
           }
         }
  }


I tried running the above code in two different network

1) System with proxy setting - execution failed got 
"java.net.SocketException: Operation timed out: connect:could be due to 
invalid address"
2) System without proxy settings -  executed sucessfully

I got  this code from "http://commons.apache.org/httpclient/sslguide.html"
This code is to test the SSL and JSSE configuration.


can anyone help me out to make this code run successfully in the system 
having proxy settings enabled. 


Thank You

Viswa

Viswa,

System proxy settings do not apply to plain Sockets. You can use
HttpClient to establish a secure tunnel via a proxy, see this sample:
