For transmitting and receiving RTP packets, I would suggest looking into the jlibrtp library. Basically you initialize it with 2 DatagramSockets (one for sending RTP data and one for receiving RTCP data), define a payload type, add a recipient, and send byte arrays. I beleive it handles the RTP timestamps by itself, but you have to make sure you're payload is already formatted by the RFC reccommendations.

Here is an example of how you would set up an RTP session
