Two new stories have been published this week and both of them use GlassFish 3.1 in production. If you haven't seen them before, "Stories" is a blog with production use of GlassFish by small, medium, and large users with user questionnaires describing their experience with the rest of the community.
The first story is PointDebate, a "social network company that stir up, engage and give voice to most diverse opinions". They've been following pretty closely all the recent updates of GlassFish and now run the latest 3.1 version (only a month after it was released). They application is built using Java EE 6 and JSF in particular with RichFaces. The full architecture includes MySQL as well as EHCache and uses JMS to "decouple operations" (an somewhat underutilized architectural pattern if you ask me).
The second story, TinyHabits, an online service "to maintain a healthy lifestyle despite leading a busy life that leaves very little time to incorporate healthy habits" is yet another Java EE 6 application with GlassFish as a platform chosen for its simplicity and robust administration and monitoring. This service also just moved to the latest and greatest version 3.1 (from 3.0.1), also uses JSF 2.0 (with PrimeFaces this time), uses both PostgreSQL and MongoDB and runs production on Amazon EC2. Check it out.
