David Heffelfinger's Java EE/GlassFish Adoption Story at JavaOne 2013

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.

Parleys Testimonial at GlassFish Community Event, JavaOne 2012


Parleys.com is an e-learning platform that provide a unique experience of online and offline viewing presentations, with integrated movies and chaptering, from the top notch developer conferences and about 40 JUGs all around the world.

Stephan Janssen (the Devoxx man and Parleys webmaster) presented at the GlassFish Community Event at JavaOne 2012 and shared why they moved from Tomcat to GlassFish. The move paid off as GlassFish was able to handle 2000 concurrent users very easily. Now they are also running Devoxx CFP and registration on this updated infrastructure. The GlassFish clustering, the asadmin CLI, application versioning, and JMS implementation are some of the features that made them a happy user.

Recently they migrated their application from Spring to Java EE 6. This allows them to stay away from getting locked into a proprietary framework and also avoid 40MB WAR file deployments. Stateless application, JAX-RS, MongoDB, and Elastic Search is their magical forumla for success there.

Watch the video below showing him in full action:

More details about their infrastructure is available here.

Human based workflow from Imixs Software Solutions using Java EE 6 and GlassFish


Imixs Software Solutions story was published on this blog 4 years ago. They provide an open source human-based workflow software that can be integrated in any Java application. They have migrated from Java EE 5/GlassFish v2 to Java EE 6/GlassFish 3.1 since then.

Migrating to Java EE 6 makes their architecture more flexible and removes restrictions on scalability and transactions. EJB 3.1 Lite and JPA 2.0 that makes it much easier to integrate the workflow engine into Web and Enterprise applications. The workflow modeler is built on top of Eclipse and the changes can be deployed during runtime without restart of the container.

Try the bits at imixs-workflow.java.net or more details on their community website.

Make sure you read the updated Imixs detailed questionnaire for further information on how Java EE 6 and GlassFish 3.1 is used to serve their need.
