One of the most important things to do at this stage of the life-cycle of Java EE is highlight successful adoption stories. We have been doing just that for a long time through our adoption stories blog as well as JavaOne. JavaOne 2014 was particularly good in this regard and JavaOne 2015 looks to be even better. Indeed we hope the folks with great adoption stories that submitted last year but did not get accepted will resubmit next year. We will highlight some of those sessions from JavaOne 2014 in the next few months and the best place to start is the Java EE adoption story from Rakuten.
Rakuten is one of the largest online financial systems in the world. It is the number one e-commerce platform in Japan generating over 51 billion dollars of yearly revenue and growing on a global scale. It is easily one of the most technically adept companies in Japan and perhaps the world. They had a legacy system build around J2EE and a hodgepodge of various non-standard frameworks such as Spring, Apache Axis and iBatis. They chose to adopt Java EE over these technologies including alternatives such as .NET. They cited vendor neutrality, choice, simplicity, community, ease-of-learning, ease-of-use and productivity as great reasons for selecting Java EE for their next generation platform. They fully leverage Java EE including key APIs such as JSF, CDI, EJB, JPA, JTA and JMS. Along with Java EE they also chose WebLogic as well as Oracle DB/Exadata. They cited performance, scalability, reliability, productivity and support for choosing WebLogic, Oracle DB and Exadata. They also use best-of-breed tools such as NetBeans, Maven, Jenkins and the Atlassian suite of solutions. They achieved the astounding technical feat of completely overhauling their 24/7, extremely high volume online transactional system in just six months including training!
You can see Hirofumi Iwasaki and Arshal Ameen's awesome JavaOne 2014 presentation below (if you are having trouble seeing the embedded video it is available here).
The slide deck from the talk is posted below (if you are having trouble seeing the embedded slideshow it is available here).
Hirofumi Iwasaki and Arshal Ameen have been great advocates of Java EE, especially in Japan. We hope to continue to see great things from them and Rakuten. Rakuten is looking forward to learning and applying Java EE 7 in the real world as soon as possible.
If you have a great Java EE adoption story to share, please do drop us a note (particularly migration stories from other technologies). In the spirit of Java EE centric vendor neutrality, what Java EE implementation or tool set you choose does not matter at all and neither does which part of the globe you are in.
