I have successfully used the TCLFilter to separate application specific logging events ["APPLICATION_ONE", "APPLICATION_TWO"]. The problem is that application specific events are also being logged to my DailyRollingFileAppender ["FILE"], which is undesired behavior. What is the best way to eliminate this duplicate logging? I attempted to configure multiple TCLFilters in DailyRollingFileAppender ["FILE"] using AcceptOnMatch param = "false", which works a single TCLFilter is used, but because of the way the TCLFilter is written (see TCLFilter.java below), multiple TCLFilters cannot be used in this way(I need to filter both application specific logging events from DailyRollingFileAppender ["FILE"]). I am new to log4j, what am I missing here? Is there another way? TCLFilter.java ******************************* ..... public int decide(LoggingEvent event) { int ok = Filter.DENY; if( acceptOnMatch == true ) { ok = Filter.DENY; if( isMatchingTCL() ) ok = Filter.ACCEPT; } else { /** * ok ACCEPT by default, if isMatchingTCL() returns false, no other filters are evaluated */ ok = Filter.ACCEPT; if( isMatchingTCL() ) ok = Filter.DENY; } return ok; } log4j.xml ******************************* I attempted to post all of the appenders, but the forum would not accept it for some reason... <appender-ref ref="CONSOLE"/> <appender-ref ref="FILE"/> <appender-ref ref="SMTP"/> <appender-ref ref="APPLICATION_ONE"/> <appender-ref ref="APPLICATION_TWO"/> View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3977027#...
