Check the "Java Gaming Resources" link just below the JGO logo!
Also, this thread has some good books listed:http://www.java-gaming.org/topics/tutorials/23958/msg/211369/view/topicseen.html#new
Scroll down to the bottom of the first post.
I just sent off for a copy of the Brackeen book. The chapter on sound looks really good (my particular interest) despite being 8 years old. The sound coding libs have been relatively stable.
I don't particularly recommend the Harbour book, though some folks do. I was able to get his "Asteroids" knockoff working OK, but felt rather mystified by many aspects of his programming, which seemed rather C++ influenced. But I was really a rookie when I read it, and maybe should reassess my opinion now that I know more.
I learned some good stuff from "Killer Game Programming" but that was after already learning how to do basic game loops.
You might just check some of the tutorials listed. Many are quite helpful.
