Recent GlassFish endorsements
By alexismp on oct. 07, 2009
• Servlet 3.0 (JSR 315) support in Maia
• How to install and use JRebel with Glassfish and Eclipse IDE
• ColdFusion - Installation, deployment, and platforms
• New Java-monitor probe for Glassfish users.
I think I also saw something recently on either EHCache or TerraCotta as well...
