It’s really a simple process, despite the not-so-simple history surrounding Enterprise Application Servers, and GlassFish almost makes it fun 🙂 The next version, GlassFish v3, allows Rails application to be deployed natively, i.e. no packaging is required. You create a Rails application and run it – just the way you are used to! Read all about it here. All previous entries in this series are archived at LOTD.
