I've used XDoclet and Hibernate for quite some time - but I'm sure I could stand to learn more. That's why I'm linking to this XDoclet and Hibernate Tutorial (found on JRoller). Hopefully I'll have some time to read through it after the long holiday weekend.
I've been looking for an app server performance comparison for some time now. Maybe those folks that say Tomcat sucks and Jetty rules will change their tune. Via Lasse Koskela:
Web Performance Inc. has published a very interesting report, which included a couple of surprises. Jetty pretty much sucked, JRun was one of the top guns, and Tomcat wasn't too far behind JRun.
Anyone know of any similar (recent) comparisons?
