mcenhillk writes After years of being a second class citizen in the J2EE world, Sun officially supports Mac OS X. The [https://glassfish.dev.java.net Glassfish] project has been running on Darwin for a couple of years now but there has never been official support from Sun. [JBoss](http://labs.jboss.com/) has been the default application server since 10.3 but I always had a problem trying to administer the system. Most other appservers I have tried over the years will run but the setup and runtime scripts have to be hacked or reverse engineered . I never had the time or patience to rely on a hack. Head on over to [Sun’s download page](http://java.sun.com/javaee/downloads/index.jsp) and give it a shot.
This is outstanding news for those of us in the tech industry that work with Java on the Mac. Thanks SUN for finally taking this on.
