O'Reilly has launched a new site called CodeZoo. It's a repository of open source Java components that can be downloaded and incorporated into programming projects. This ia a great idea for hobbiests and people in industry and I wish them all the luck in the world. I'm just glad I don't have to teach (and mark) any kind of Java programming courses. Java teachers of the world, make sure you know what's in here before you set your programming assignments. Some resources here, here, here and here.
