Dan Allen

Dan Allen is a passionate enterprise software developer, scholar, and mentor. For Dan, the end game is to be a mentor, and writing is one medium he uses to pursue that goal. Dan has over eight years of development experience using technologies that include Java frameworks (Seam, JSF, EJB3, Hibernate, Spring, Struts), testing frameworks (JUnit, TestNG), JavaScript and DOM scripting, CSS and page layouts, Maven 2, Ant, Groovy, as well as a wealth of other technologies not mentioned. Dan is also a dedicated open source advocate, and is very proud, and not a tad bit shy, about the fact that he has been running Linux, and only Linux, since the turn of the millennium. Dan's professional passions are equally divided between Java and Linux, with a hint of other technologies mixed in.

All too often, developers spend a majority of their time integrating disparate technologies, manually tracking state, struggling to understand JSF, wrestling with Hibernate exceptions, and constantly redeploying applications, rather than on the logic pertaining to the business at hand. Seam in Action dives deep into thorough explanations of how Seam eliminates these non-core tasks by leveraging configuration by exception, Java 5 annotations, and aspect-oriented programming.

To start off, you will see a working Java EE-compliant application come together by the end of the second chapter. As you progress through the book, you will discover how Seam eliminates unnecessary layers and configurations and uses an inversion of control technical known as bijection supplemented by a liberal use of the Unified Expression Language (EL) to establish the missing link between JSF, EJB 3 and JavaBean components. You also witness how Seam opens doors for you to incorporate technologies you previously have not had time to learn, such as business processes and stateful page flows (jBPM), rule-based security, Ajax remoting, PDF generation, Spring integration, and more.
