Java Articles/Blogs

It has been around a year when I started reading blogs but most of the blogs I read hardly anything to do with my job i.e. Java. I have been subscribed to newsletter off http://www.javawolrd.com and http://java.sun. com but I still want more latest tutorials about Java. Can someone please point me out some good blogs related to Java?
