Java Application Architecture: Modularity Patterns with Examples Using OSGi

The design patterns introduced by the Gang of Four in the mid-nineties revolutionized the world of object-oriented programming, and of software development in general. Today most programmers use design patterns as a matter of course in their everyday work. More recently, folks such as Bob Martin have introduced the next level of abstraction, design principles, which are rapidly gaining acceptance. Java Application Architecture takes this evolution of object-oriented programming to its next logical stage, introducing eighteen patterns for modular architecture, identified by the author.
