In principle you have to read the file on your client application, open an OutputStream to the server, and write the contents of the file to this stream. On the server you read from the other end of the stream.

Depending on your architecture, you either will use a new socket-pair for the file transfer, or somehow embed it into your existing communication protocol.

It would be better to use a Messaging Application for your purpose. I would recommend using JMS. I personally use ActiveMQ . If this does not suit your need then try out Apache Mina. It would abstract you from the Network Programming.
