As we've mentioned, GlassFish got a lot of attention at this year's JavaOne conference. So it shouldn't be surprising that it also got a lot of attention when the Java Posse guys shared their own JavaOne Restrospective [podcast, resources].
The GlassFish discussion goes from around 17:15 to 24:30 in the podcast. They start off by talking about the GlassFish v3 demo: "All you need to know ... is cycle time of less than a second to start the application server ... that is rule-changing." That's a nice endorsement of GlassFish's future, but they clearly think it has also plenty to offer right now. Not pulling any punches, one of the guys sums up his opinion of GlassFish as an application server: "It's the best one I've used of them all."
That's just a sampling of the discussion, though. They also touch on marketshare trends, the dynamics between closed-source and open-source implementations, the benefits of being a Reference Implementation, and more. It's definitely worth a listen.
