I started a video tutorial series for rosjava.
I just put the first video on creating rosjava workspace and is added to the
Wiki
http://wiki.ros.org/rosjava_build_tools/Tutorials/hydro/Creating%20Rosjava%2
0Packages#preview

I will add more videos soon on rosjava tutorials including explanation of
Talker Listener and making more advanced applications with rosjava.

This is the link of the YouTube playlist for future rosjava tutorials

Hope this will be helpful.
