Sorry Damon, My Mistake
NodeConfiguration has member xmlRpcPort which is 0 by default.
Its not set any where and is used to creare tcpRosBindAddress and passed to
SlaveServer as a parameter.(See internal node constructor)
SlaveServer is later using it to create TcpRosServer. and so on.

Thanks and Regards
Abhishek Verma
