Adam Bien - Real World Java EE Patterns-Rethinking Best Practices

Since the publication of the first edition of RealWorld Java EE PatternsRethinking Best Practices , the enterprise landscape hasdramatically changed. Because of theamazing productivity provided by Java EE, smaller companies and startups havebegun to use Java EE for building a variety of interesting applications, fromNoSQL data store integration to communication with robots over sockets.

I used the patterns and utilities describedin the first edition Rethinking in all my Java EE projects. Gettingthings done became more important than any shiny frameworks. With a littlehelp from Java EE 6, previously challenging tasks turned into a few lines ofcode and couple of annotations. I began to gather and re-implement thesolutions from my projects and push them frequently to http://kenai.com/projects/javaee-patterns.

The Rethinking book is a catalog of ideas, patterns,and workarounds. Many readers asked for a real world application built upon theconcepts described in the Rethinking book. It was a challenging request, because,as a consultant, I always have to sign an NDA before any of my real workstarts. However, during one of my nightly hacking sessions, I got a spontaneousidea for my second book, Real World Java EE Night HacksDissecting theBusiness Tier (press.adam-bien.com). In theNight Hacks book, I described one of my Java EE 6 hacksa blogstatistics application called x-ray (x-ray.adam-bien.com),which I created for real time monitoring of my blog: blog.adam-bien.com. I developed x-ray fromscratch; it is a real world application that is dangerous (it could crash myblog, which has approximately 10,000 visitors a day) and there is no NDA, so itwas perfectly suitable as a sample application for a book.

The x-ray application is a native Java EE 6application entirely built with concepts from the first edition of the Rethinkingbook; I even had some specific problems to solve, the solution to which emergedas new patterns. The Late Starter, Configurator, and Telemetry Providerpatterns were extracted almost without any modification from x-ray.

Also, my continuous emphasis on theimportance of stress testing resulted in a new project: lightfish.adam-bien.com. I built theLightFish monitoring application with Java EE 6 and used scripting forescalation of suspicious behavior. I extracted some code from LightFish toprovide you with another NDA-free samplethe Fluid Logic pattern.

The first edition of Rethinking camewith a Java EE Connector Architecture (JCA) 1.5 connector implementation, whichgot some attention as well. In this second edition of Rethinking, Iimplemented a JCA 1.6 connector from scratch and extracted it into a standaloneApache-licensed project: connectorz.adam-bien.com.

I'm always open to feedback and discussion-so I can learn fromyou, the reader. Just drop me an email (abien@adam-bien.com) and I'll be sureto incorporate your feedback in a future update of the book. Also, keep an eyeon my blog (blog.adam-bien.com), where I willcontinue to cover the topics discussed in this book.

If youd like to code something with me inreal time, check out workshops.adam-bien.com.I regularly organize short hacking workshops at Munichs airport. I call thatairhacks.com.

Special thanks to my wife Kinga (design.graphikerin.com) for the cover,Patrick for the in-depth technical review and unconventional feedback, and myeditor Karen Perkins (http://www.linkedin.com/in/karenjperkins)for editing and pragmatic collaboration.

The book Real World Java EE Night Hacks--Dissecting the Business Tier describes end-to-end development of a real world Java EE application.After the first edition of the Real World Java EE Patterns--Rethinking Best Practices I gotmany requests for a book about developing a Java EE application from scratch. Real World Java EE Night Hacks walks you through the Java EE 6 best practices and patterns used to create a real world application called x-ray .X-ray is a high-performance blog statistics application built with nothing but vanilla Java EE 6 leveraging the synergies between the JAX-RS, EJB 3.1, JPA 2, and CDI 1.0 APIs

James Gosling "father of Java" also liked Night Hacks --and wrote a preface.

There is also an executable and interactive version of both books available. See you at: airhacks.com!
