This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
I don't think the Journal would have been a good way to keep tabs on what's happening in the Java world ever since publication ceased to be monthly (which happened in 2004). It's doubtful whether there will be a new issue any time soon - we haven't had article submissions in a while now.
I recommend following sites like TheServerSide and "Week in Review" on java.net (and reading what gets discussed here on the Ranch, of course).
