I have found the problem. It is several layers of fragile junk being mis-labeled as logging systems. The main culprit is Tomcat's new JULI logging system, new since Tomcat 5.5.9 I believe. This piece of junk is a sophisticated system which allows each individual application to have its own logging. Unfortunately it achieves this by not logging anything, and by re-assigning System.out so even println doesn't work anymore. Now I have to see if there is some way to disable it or force it to actually log log messages. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4002076#...
