How do you find out about new Java technologies, tools and specifications?

My favorite place for hard working geniuses: http://stackoverflow.com/

- For specification there is one resource Oracle, they issue the specifications companies and community implements them.
- For Java technologies, tools and what is new in Java world, because of the big technology stack that is around Java every developer has to use multiple resources:1.
Magazines: Java magazine and eclipse magazine are good resources.2.
News.3.
Books.4.
Colleagues.

stackoverflow.com

Listen to the Java Posse podcast.
It is fun, it is relevant and gives a great feel of the Java (and wider JVM) community.
It also has sections on Scala, Groovy, Android and (from time to time) Clojure.
Look for it on iTunes or your other podcatcher of choice.

Must follow the oracle.com site with there blog and newsletter for java developers

AFAIK, the best bet websites to get updated with new java tech are : dzone.com infoq.com www.theserverside.com and stackoverflow.com/questions
