That's a fair point, I guess I've been spoiled. I guess I just don't mind knowing those integration points and working with them, but I can definitely see how it would put a bad taste in your mouth after a while. The NoSQL integration I think will be big. I know some folks using SpringData to talk to MongoDB and they've had positive experiences so far. Maybe in the future things will get simpler - so far I've found that I'm pretty happy with either embedded Jetty or Tomcat. And then Spring/Jersey + Hibernate/JPA. Have you found that EAR/WAR size has hampered you? I tend not to worry about how many JARs I'm pulling.

I use GF3.1 as they are the only one that implement JEE6 in full. There's an issue with deploy/undeploy app (memory leak due to pushing ClassLoader to the edge) which is kind of annoying to me personally because we do frequent build/deploy. I wish we can use Jetty (I used Jetty, Servlet, GWT in my previous company) since it is way leaner and faster to reboot; especially via Maven. Although I've never measured the deployment performance, I'm quite sure the smaller your EAR/WAR size the faster it deploys because the ClassLoader is required to scan + load those libraries (again, it depends on the behavior of your library: up-front or lazy loading).

  I recently moved from Glassfish back to good old Tomcat because of this classloader leak. With GF, I could typically do no more than 1-2 redeploys before having to kill -9 it. That was really painful. We found that we weren't really using many GF/JEE features that couldn't be added to Tomcat as a simple jar dependency (J2EE connection pooling was one nice built-in, but we'll use c3p0 or something similar soon). Tomcat is a breath of fresh air- starts/stops in < 4 seconds, and redeploys never hang.

  You definitely want to try jrebel to solve your problems with redeploys and wasting time. It'll reload your classes and resource as you compile/provide them. Check it out, http://zeroturnaround.com http://zeroturnaround.com . disclaimer: I work there, but jrebel is awesome anyway.

    I have heard of JRebel for a while but have not had the case to need this until now. Is it free for development? PS: I saw someone from JRebel did a presentation about ClassLoader before, you guys really know what you are doing. Respect man! :)
