You need to understand Oracle Net, formerly called Net8. This is like another layer above ( or under ) the TCP/IP stack. It use 1521 by default. You should not be trying to use Java to connect directly to this port.

APP --->Net8 ----> tcpIP -----network-----> tcpIP---->NET8(1521)----->Oracle Instance
