Hmm, looks like the new documentation is making things harder than what they need to be. Oh well. And you are right, JBossAS 5.0.0.Beta4 source download will not compile. Looks like the source download was not packaged correctly. I looked back at what I did and realized that I did not download the source bundle and compile that. Instead, I extracted the source files from the JBoss_5_0_0_Beta4 tag in Subversion and compiled that (with JDK 5 and JDK 6). I just now did that again and it compiles, and runs, just fine. You can get the source using: svn co http://anonsvn.jboss.org/repos/jbossas/tags/JBoss_5_0_0_Beta4/ View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4140227#...
