hello, Here is my smtp appender configuration in jboss/server/conf/jboss-log4j.xml. When ever i start run.sh, it is throwing following exception. log4j:ERROR Could not instantiate class [C:\jbossBootPath\CustomLogEvaluator.class]. java.lang.ClassNotFoundException: C:\jbossBootPath\CustomLogEvaluator.class I have tried loading class using run.sh classpath as follows. sh run.sh -c sepsis --classpath=/cygdrive/c/jbossBootPath/CustomLogEvaluator.class Reason i am trying to use jboss/server/conf/jboss-log4j.xml instead of packaging log4j.xml inside application.ear is I would like to be able to modify the log level from INFO to DEBUG while server is running, without restarting the whole application. Thanks, kumar. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4246521#... Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&a...
