Applied patterns for J2EE

THE book to understand and use J2EE patterns effectively! Excellent concept introduction to begin with, to tide over the pattern non-gurus, comparison with established OO design patterns to ones mostly used in the J2EE community including ones on theserverside.com, plenty of demonstrable code some of which found their way into our deployed apps, great emphasis on patterns applied to specific layers of an application like persistence, web, security, performance etc. Great insight into usually tricky integration topics.

The web tier chapter details patterns that could be used for request processing with session management, view manipulation, validation and security. The persistence framework chapter was perfect for our implementation with its data access layer strategy based on DAOs and value objects, though we would have liked to see some transaction management patterns. The scalability and performance concerns have been closely investigated, as have all security designs like single-access, check-point and role patterns. A working example targeted for a leading app server could have proved useful here, though there is plenty of code available for download. After all is said and done, the chapter on integration where everything comes together nicely, scores top marks for topics not usually found in other books.
An excellent addition to anyone's J2EE repertoire.
