Then created new server instance in Eclipse. But server start up fails. I used JBoss AS 7.1.1 Brontes. Platform is Mac OS X 10.6.8. I managed to deploy though hello world and logIn Examples. The server starts via console and the example apps are deployed and working properly. There seem to be a problem when starting JBoss AS 7.1.1 from within Eclipse. The error message on Server startup from Eclipse looks like " Exception in thread "main" java.lang.NoClassDefFoundError: /Applications/jboss-as-7/1/1/Final Caused by: java.lang.ClassNotFoundException: .Applications.jboss-as-7.1.1.Final           at java.net.URLClassLoader$1.run(URLClassLoader.java:200)           at java.security.AccessController.doPrivileged(Native Method)           at java.net.URLClassLoader.findClass(URLClassLoader.java:188)           at java.lang.ClassLoader.loadClass(ClassLoader.java:315)           at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:330)           at java.lang.ClassLoader.loadClass(ClassLoader.java:250)           at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:398) " Any ideas?
