Any idea why I am getting java.net.ConnectException, running both NonBlockingServer.java, and, Client.java? Tried to use telnet to connect to port 4900 on the localhost, however, the connection fails.

Windows Firewall is off on my laptop running WinXP SP3.







Server output - Displayed when running NonBlockingServer.java
Inside default ctor
Inside startserver
Inside initialization
Abt to block on select()

Error displayed when running Client.java
java.net.ConnectException: Connection refused: connect
at sun.nio.ch.Net.connect(Native Method)
at sun.nio.ch.SocketChannelImpl.connect(SocketChannelImpl.java:500)
at Client.makeConnection(Client.java:29)
at Client.main(Client.java:109)
Inside SendMessage

Command line

If telnet is failing as well then the problem is somewhere in your server. Ignore the client for now.

I've added some println statements but the server appears to hang on the selector().select() method.
