Yener M., Theedom A. Professional Java EE Design Patterns

John Wiley & Sons, Inc, 2014. — 264 p. — ISBN13: 978-1-4920-0782-1.Patterns are essential design tools for Java developers. Even though Java EE provides default implementations for many classic GoF patterns, most experienced developers underestimate the value of these out of the box implementations.
Professional Java EE Design Patterns helps developers attain better code quality and progress to higher levels of architectural creativity by examining the purpose of each pattern and demonstrating its implementation with various alternative code examples.
Beginning with the most common Gang of Four patterns and progressing to newer patterns, you’ll rediscover their classic form and then learn their Java EE specific implementations via in depth discussion and code samples. Patterns are brought to life through good and bad war stories, sometimes funny, sometimes frustrating but always illustrative of the principles at stake.
