EJB Design Patterns
The job of the EJB developer is constantly challenging, making the task of designing maintainable and scalable systems difficult without a clear set of best practices to follow. It is with this and other concerns in mind that Floyd Marinescu (Director of TheServerSide.com J2EE Community) worked with thousands of J2EE professionals on TheServerSide to put their collective knowledge together in order to build a library of design patterns, strategies, and best practices for EJB design and development.
EJB Design Patterns goes beyond high-level design pattern descriptions into critical EJB-specific implementation issues, illustrated with source code implementations. The book contains a catalog of twenty advanced EJB patterns and provides strategies for mapping application requirements to patterns-driven design, J2EE development best practices, and a collection of EJB tips and strategies, and other topics such as Build-System best practices using Ant, JUnit testing strategies, using Java Data Objects (JDO) as an alternative to entity beans, and more.

On p53 it is recommended that DTO's be used as arguments to ejbCreate,
but then this behaviour is discouraged on p204. This was an oversight.
The author recommends using limited primitives as arguments, as
described on p204.

This page is missing a paragraph. The first paragraph on the page (above the one beginning with "One important..." should be: "A source code example of a Business Delegate for a Stateful Session Bean that can be serialized is included in Appendix B, under Business Delegate. This example provides serializability in a completely transparent fashion - other than throwing it into an HTTPSession, the client of the business delegate doesn't need to handle it any differently than it would a delegate for a stateless session bean."
