I need to load my log4j.properties file instead of using jboss default configuration (jboss-log4j.xml). So I need to specify the classloader. In wiki: http://wiki.jboss.org/wiki/ClassLoadingConfiguration, It talks about the configuration for both ear, war and sar, but not .esb. Does anyone know how to config for esb file? Shall I use jboss-app.xml for .esb? Thanks, Lihui View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4148415#...
