EJB Design Patterns eBook

EJB Design Patterns
By Floyd Marinescu

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.

Floyd Marinescu draws on his work building TheServerside.com J2EE community site and offers best practices for three different strategies used in creating primary keys for entity beans: sequence blocks, UUID for EJB, and stored procedures for autogenerated keys.
