This third volume from Mark Grand features 38 design patterns for developing real-world Java distributed and enterprise applications. Some of the key concepts covered are reliable transaction processing, distributed objects, reliable message passing, concurrency management, object persistence, and coping with time. The popularity of technologies for dealing with these issues waxes and wanes. However, by explaining many of the problems that technologies such as J2EE are designed to solve, this book documents the skills necessary for designing software that will remain useful with both current and future technologies.
