This book is truly the complete book on EJB Specification 2.1 and more. By more I mean to say that not only does it focus on EJB and their real life implementations but also on the underlying technologies of distributed programming like RMI-IIOP and JNDI. It talks about the best practices and performance optimization techniques that can be used while working on EJBs. For me this book the holy book on EJBs.
This for people who do not know about EJB much and for those who are already grandmasters on them. For beginners, this book might look very heavy initially but slowly and slowly as you try to sink into the chapters you will get excellent conceptual knowledge about what EJBs are and how they are used. For masters, this offers the best reference manual available in the market.
