The JavaHispano Oct 2008 poll covered AppServer adoption. Despite the methodological challenges in self-selected polls (, ), I think this one is a bit more accurate because it is more community focused.
Eyeballing the Results Page, with a sample of 1197, Tomcat had ~550 votes, JBoss ~180 and GlassFish ~170; which is a better showing for GF than I was expecting for this community.
The SOA WSJ Reader's Choice poll is still ongoing and the projects related to GlassFish are doing very well.
