EJB 3.1 Cookbook by Richard M. Reese
Each recipe comprises step-by-step instructions followed by an analysis of what was done in each task and other useful information. The book is designed so that you can read it chapter by chapter, or look at the list of recipes and refer to them in no particular order. It is packed with useful screenshots to make your learning even easier. The book is aimed at Java EE and EJB developers and programmers. Readers should be familiar with the use of servlets in the construction of a web application. A working knowledge of XML is also desirable.
