David Heffelfinger is the Chief Technology Officer of Ensode Technology, a software consulting firm based in the greater Washington DC area. He's authored several Java books, including 4 titles covering Java EE and GlassFish. He has done work at places like the Department of Housing and Urban Development, the Department of Homeland Security, the Department of the Army and U.S. Customs and Border Protection. David shared his Java EE/GlassFish adoption story at the JavaOne 2013 Sunday GlassFish community event - check out the video below:
Here is the slide deck for his talk:
He detailed how he convinced a long time customer that wasn't very technically savvy to upgrade their application servers and use Java EE/GlassFish with PrimeFaces. The customer was very reluctant at first and wanted to keep using their older infrastructure. Hacking together a visually impressive proof-of-concept quickly using Java EE and PrimeFaces did the trick for David. Using the combination of Java EE 6, GlassFish, PrimeFaces and NetBeans allowed him to lead a relatively inexperienced team in delivering the first version of the application in just three weeks! The Java EE application David still actively maintains runs on a two server GlassFish production cluster.
David also mentioned that using GlassFish as a learning tool helps keep his skills sharp and in-demand as GlassFish adopts the newest Java EE APIs faster than the other options.
