Glassfish in action (Screencast)
By John Clingan-Oracle on Mar 26, 2007
If you are interested in Glassfish, RoR, Phobos, PHP or application servers in general, check out Jerome's Glassfish v3 screencast. Note, the title of the post says "first", so I'm assuming there will be more coming.
What's nice about Glassfish v3, which the screencast delves into, is the improved startup time. Me-thinks that a sub-second up-and-running web container should facilitate design-time and allow developers to better focus on the problem at hand. Quick-startup is enabled by a newer, more modular approach in line with JSR 277.
