Socket closed but still connected

[Anonymous]

Hi !

Again, I'm clueless. I have a java.net.Socket called socket which I want to close (disconnect from the peer). I can close the socket, but I can't disconnect it:

(socket.isClosed()) returns true, but (socket.isConnected) remains true as well. How can I fully cut the connection ? The socket is associated with a java.nio.channels.SocketChannel.

Thanks in advance,
Dennis

I found a solution but I don't understand it.
To close the TCP connection, I had to invoke a select on the selector responsible for reading from the socket:

  
connectionKey.cancel();
 
// without the following call, the socket is closed but the TCP connection remains 
// active. (isClosed() == true, isConnected() == true)
selector.selectNow();  
socket.close();

Any ideas ??
