Ipso-Facto builds and delivers real estate software as a service for the French market. They've been running GlassFish v2 in production for a little while now. Enough to call it "mature, recommend (it) for professional use" and start the rewrite of older applications to run on top of this Java EE server.
This company used to be a full Microsoft shop and first moved to Java with Tomcat before they adopted GlassFish. Their largest application, LogissimoASP, uses many JSF components from various sources, and operates in a Microsoft environment: Windows 2003 and SQL Server 2005. This application recently started using the clustering and load-balancing features provided by GlassFish v2 to secure the availability of the service which now has hundreds of concurrent users and spikes at well-known moments in the day.
