Daniel posted a few weeks ago this blog entry about a code camp he and others have been running for ISVs to port and develop their applications on the GlassFish Application Server.
Don't be put off by the page being in German, all of the GlassFish Workshop documents are in English and very good IMHO. They cover from GlassFish fundamentals such as basic installation steps to much more advanced details about how to adapt applications and their packaging for GlassFish.
Here's a list of those documents :
• Getting started, Introduction and Migration.
• Resource Management &
Call Flow Monitoring.
• Clustering & Load Balancing.
If you're more into following slides, here's a good deck.
