title: Send data back to client with UDP using Apache Mina
body: <p>I am using Apache Mina to create a server to accept UDP Client requests. I have read the Official documentation provided by Apache Mina regarding <a href="http://mina.apache.org/udp-tutorial.html" rel="nofollow">UDP Server &amp; UDP Client</a>. However, I wished to know when the server receives a message, can I write back to the UDP Client using the same session(I know UDP is connectionless at Network Layer, however I can get the IP and PORT of the remote host at Application Layer) such that UDP Client receives a message. I know this is possible is TCP but am a little confused about UDP. I know this may not exactly be Java based but more Network Layer based question. Would appreciate if somebody could clear this for me.</p>
