"The reports of my death have been greatly exaggerated."
– Mark Twain
It sometimes seems like there has been a raging debate on the role of Java EE in server-side Java since the beginning of time. The debate is perhaps just as old and stale as the question of whether Java is finally dead or irrelevant. One of the latest dimensions of this debate has been around adoption of Java EE 7. It is not too surprising then that DZone took up the topic in it's wide ranging 2015 Java Ecosystem Survey. The analysis of the results of that survey will be part of the upcoming 2015 Java Ecosystem Guide to be published during JavaOne. Fortunately DZone shared the results with a selected set of MVBs (Most Valuable Bloggers) including yours truly and gave me permission to share some preview perspectives on the data. As the title of this entry suggests the survey results bode well for Java EE 7 specifically and Java EE generally.
The survey asked a very simple question - "Which of the following Java platforms do you use today?", including various versions of Java EE and some key alternative technologies as mutually inclusive answers (I think the mutually inclusive part is an important reality check towards the aforementioned debate that generally tends to have a tone of mutual exclusion). As the results highlighted shows, almost 39% of developers chose Java EE 7. A total of over 90% responses chose one version of Java EE or the other - well ahead of the other technologies listed. Java EE 7 community support seems to have already edged out the very well regarded Java EE 6 release. These patterns will likely get even stronger with the recent Java EE 7 release of WebSphere Liberty and full commercial support of Java EE 7 through WebLogic and JBoss EAP in the next coming months.
Fortunately we also have interesting past data points to compare in the RebelLab's 2014 Java Tools and Technologies Landscape survey. That survey asked similar but slightly different questions with regards to Java EE. In that survey 68% indicated that they were Java EE users, which is likely a lower rate than in the DZone survey. Most importantly a significantly higher percentage, 49% indicated Java EE 6 usage than Java EE 7 usage that stood at 35%. For clarity this report treated Java EE version usage as mutually exclusive (probably a mostly reasonable assumption). It did not attempt to collate data on Java EE vis-a-vis alternatives. To roughly compare with the DZone report format that means that of total respondents, about 24% reported Java EE 7 usage while 33% reported Java EE 6 usage. All this bodes well for Java EE and Java EE 7. The two surveys taken roughly a year apart indicate higher levels of usage for Java EE overall and strengthening community support behind Java EE 7, even as compared with Java EE 6.
On behalf of the Java EE team here at Oracle it is only correct to thank everyone that indicated their support for Java EE and Java EE 7 in such surveys. Our work is intended to benefit you first and foremost - it is good to see that intent does not get lost in the muddle. As you may be aware we make an effort to highlight your success adopting Java EE in our blogs, JavaOne and through the core Java EE community. It is always a good time to drop us a note to share your story with the broader community.
