I tried putting this: | <Logger className="org.jboss.web.tomcat.Log4jLogger" | verbosityLevel="INFO" | category="org.jboss.web.localhost.Engine" /> | in the web server.xml file for JBoss and that made the whole thing fail. Hmm, surely logging is possible for applications in JBoss? I just want to do the obvious things: if there is an uncaught exception, log it, and also be able to say logger.severe("somethign happened"). This shouldn't be brain surgery here...
