This week's book giveaway is in the OO, Patterns, UML and Refactoring forum. We're giving away four copies of Refactoring for Software Design Smells: Managing Technical Debt and have Girish Suryanarayana, Ganesh Samarthyam & Tushar Sharma on-line! See this thread for details.
And also check the technical documentation of your application server. Sun documents their end of the deployment but many appservers have their own deployment descriptors as well for linking the standardised ones with appserver specific things like JNDI resources and URIs.
