JBoss AS (and JBoss SOA) are pure Java, thus they should run the same on any operating system that has a JVM. Having said that, you can run into networking/firewall and permission issues because some OSes have security tightened down more than others. But the OS vendor should provide the necessary information on how to configure your security settings to open ports and do other such things. I have Server 2008 running in VMWare. I think that I ran JBoss AS there with no issues (it's been several months since I used Server 2008). View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4200385#...
