I was going to point this out earlier and completely forgot about it - get JBoss AS out of Documents and Settings! Spaces in path names cause certain Java libraries fits. I have mine at d:\opt\jboss\jboss-5.0.0.GA. In fact, I don't even let the JDK install itself on Program Files, mine is at c:\apps\Java\jdk1.6.0_12. (You can simply move or copy the JDK and change JAVA_HOME accordingly - no need to reinstall.) View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4217220#...
