<p>Java Blueprints were developed to show you design patterns in enterprise Java. The Java Pet Store was designed to demonstrate the quintessential Java 2 Enterprise Edition (J2EE) application. This was mainly in the heady days of EJB 1.1-2.1, which had many failed and defective technologies, including the now-dumped Container Managed Persistence.</p><p>Around the same time, Puff Daddy became P. Diddy, then dropped the "P" with the explanation that it was getting in between him and his fans. Likewise, J2EE dropped the "2" and became Java EE possibly for the same reason. Meanwhile, Sun abandoned the Pet Store business in 2007. But Antonio Goncalves recently picked the application back up and modernized it as the Pet Shop. It uses CDI and all Java EE's latest fixings and versions to demonstrate the "right way" to do a Java EE application. You can find the code for Goncalves's Pet Store on GitHub.</p><p>[ Know your Java?

CDI is mainly a codification or "standardization" of Spring, assuming Oracle's blessing means "standardization" to you. The Spring Framework more or less won the programming model. Meanwhile, the traditional "there is only the RDBMS" thought pattern is a little less of a given now with the big data and NoSQL revolution in place. Moreover, in the era of consumerization of computing and the Web, the traditional transaction manager is less relevant. It is unlikely that a device (a la database) transaction is sufficient any longer to support consistency.</p><p><a href="http://www.javaworld.com/javaworld/jw-03-2013/130328-porting-java-ee-pet-shop-app-to-nosql.html">Keep reading...</a></p>
