The Java™ BluePrints Solutions Catalog is a new project from the Java BluePrints program. It consists of a set of guidelines and best practices and small applications to illustrate these guidelines on the J2EE 1.4 platform.
There is a lite version, which you can view online, and there is a full version, which you can download from project web site. I've only browsed the lite version so far and I like the best practises on web services. I think it's a good resource, when you start developing a new EE application, at least for me as a EE novice.
