Are many people out there using Geronimo in their live environment? We use tomcat on its own currently, but I'm keen to start using JMS and MDB in our applications and I think it would be better to move to geronimo rather than trying to get activemq working with tomcat (tomcat's jndi can act kinda weird sometimes).

I have used Jboss for production applications in the past and got bitten badly by their shared classloader for web applications (forget their name for it) where we had conflicts on jar files so we had to split the applications up and use a different classloader for each. When we split them up we came across some dreadful performance problems and as we couldn't afford jboss support, received no help from the community. How have people fared with the Genronimo community?

Anyone got any feedback, positive or negative comments?
