I'm using glassfish together with netbeans 6m2 in my current project and until now I'm still enjoying it. I wrote a blog entry, about my first experience. I also posted some ideas/feature requests to the mailing lists. Because of my past experience with some commercial and opensource appservers, I did not expected any feedback. But: I was surprised.
You will find feedback in my past comments from product managers, also some feature requests will be realized. I got extensive feedback from Roman Strobl (thanks).
This fact is in my opinion more important, than some fine grained features. It seems like Sun's tries to take developers in glassfish/netbeans space very seriously.
I tried also in the past to contribute some ideas to "netdynamics" (sun's old appserver), but my mails/ideas were simply ignored. So it seems's like Sun changed the attitude to software development. Hopefully the support and attitude in the commercial glassfish products will be as good as in the opensource community :-).
Disclaimer: I'm not a Sun employee, only a freelancer working in Java SE/EE space since the early JDK 1.0 days :-)
