I am sending the Netconf request using SnmpTransportClient as
explained in the pdf, but getting "current session has not received
hello" error message.

Hello,

  I would recommend taking a look at the trace file which contains the netconf traffic over-the-wire.

 To set up the trace file, pass in a property called "netconfTraceFile" (with the value being set to the fully qualified path-name of the file) to the Client.setup() call.

 Once you do that, you can examine the trace file and see the XML communications going back-and-forth. If you can provide me that information, it will help me figure things out better...
