GlassFish has just recorded a record-setting September in terms of downloads, registrations, and admin pings. The GlassFish downloads graph is indicative of a "breakout" for GlassFish within the application server market sphere.
I'm still a big Tomcat fan myself, but have others made the switch from Tomcat to Glassfish (or use both)? Any big advantage to Glassfish if I don't need the full JEE bits?
I wonder also if this includes downloads of Glassfish with NetBeans. Since it's the default servlet container with the full version of NetBeans that could skew the numbers a bit.
