I am getting this error when I try to deploy the simplest of applications in my JBoss application server 4.2.0-GA and 4.2.1-GA (basic web.xml with a JSP). Error configuring application listener of class |CONFIG_LISTEN_CLASS| java.lang.ClassNotFoundException: |CONFIG_LISTEN_CLASS| Any ideas what a CONFIG_LISTEN_CLASS is? I am supposed to replace this parameter with the real class in some configuration file? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4071716#...
