The TCP transport implementation is in the Apache WS-Commons Transports project. The two classes that act as the transport listener and the sender are org.apache.axis2.transport.tcp.TCPServer and org.apache.axis2.transport.tcp.TCPTransportSender respectively. In order to use the transport axis2-transport-tcp.jar should be added to the Carbon classpath.
