# Real World Java EE Night Hacks--Dissecting the Business Tier Book and Project

The book Real World Java EE Night Hacks--Dissecting the Business Tier is available as  softcover (print), Kindle (worldwide) hardware, kindle software reader (Win, Mac, Android, BlackBerry iPhone and iPad) and Adobe Digital Editions eBook (epub)
Real World Java EE Night Hacks dissects a plain vanilla Java EE 6 application "x-ray". It measures the traffic and statistics of this blog and comes with Roller 4 integration - just look at the right area to see it in action. With this post x-ray will the first time measure the popularity of itself :-). Real World Java EE Night Hacks includes coverage of:


						
	A brief introduction into the core principles of Java EE 6 (EJB 3.1, CDI, JPA, JTA,Dependency Injection, Convention over Configuration, interceptors, transactions, REST) using real world code
	Unit and integration testing of Java EE 6 applications using JUnit and ScalaTest
	Using interceptors for performance measuring and monitoring
	Creating mocks with Mockito for EJB 3.1, CDI, JPA, and JAX-RS
	Developing embedded integration tests with Arquillian
	Productive use of JAX-RS, Contexts and Dependency Injection, EJB 3.1, and JPA
	RESTful services and REST clients with Java EE 6
	Convention over Configuration with Java EE 6
	Effective component configuration with CDI and Convention over Configuration
	Plug-in implementation with CDI
	Transactional pub/sub without JMS based on CDI and EJB 3.1
	Continuous integration with Maven 3, Mercurial/Git, and Hudson/Jenkins
	Implementing configurable timers and asynchronous batch processing
	Eventual consistency and high-performance deferred writes with Java EE 6
	Real-time client and server monitoring with JMX and REST
	Functional testing with FitNesse
	Performing stress and load tests
	Simplest possible, but maintainable, Java EE 6 design and architecture


Special thanks to James Gosling, (nighthacks.com) for the foreword:
"Most books for software developers are horizontal slices through some piece of the technological landscape. "X for Dummies" or "Everything you need to know about X." Breadth and lots of toy examples. This book takes a largely orthogonal approach, taking a vertical slice through a stack of technologies to get something very real done. Adam takes as his organizing principle one real Java EE application that is not a toy, and goes through it, almost line-by-line explaining what it does, and why. In many ways, it feels like John Lions', Lions' classic Commentary on UNIX 6th Edition.
                        
One of the problems that people often have when they start looking at Java is that they get overwhelmed by the vast expanse of facilities available. Most of the APIs have the interesting property that the solution to any task tends to be pretty simple. The complexity is in finding that simple path. Adam's book shows a path to a solution for the problem he was trying to solve. You can treat it as an inspiration to find your own simple path to whatever problem you have at hand, and guidance on how various pieces fit together

Real World Java EE Night Hacks - Dissecting the Business Tier will benefit experienced developers and architects interested in code, not PowerPoint slides :-).
I will cover the topics in subsequent posts - so the content of the book will become more technical again :-). The source code was pushed into the GIT-repository: http://java.net/projects/x-ray. All samples were tested with Glassfish v3 - v3.1, developed with Netbeans 7 and IntelliJ, built with Maven 3 / Hudson, managed by Mercurial / GIT, unit tested with JUnit / Scala Test, mocked with Mockito, functional tested with fitnesse,  and quality-measured with SonarSource.
