SftpClient is producing diffent file size

I think the problem in the above code is because the executeCommand() 
method returns immediatly, as opposed to returning when the remote 
command is actually done.  What is needed in the above code is a piece 
of code that will wait for the remote command to finish, such as:

          try
          {
            
sessionChannel.getState().waitForState(ChannelState.CHANNEL_CLOSED);
          }
          catch (InterruptedException ex)
          {
            JOptionPane.showMessageDialog(null,
              "The command was interrupted!",
              "Interrupted Exception",
              JOptionPane.OK_OPTION);
          }

Putting this piece of code before the sftp code should fix the problem.

Hope this helps...
