It's working fine now. Madhav -----Original Message----- From: Rich Bagley [mailto:[EMAIL PROTECTED]] Sent: Saturday, January 25, 2003 8:47 PM To: Log4J Users List Subject: RE: Help for starter.. Hi, I think the second xml is overwriting the appender attached to root. I'd use one xml file, with multiple appenders and loggers, something like this: <?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE log4j:configuration SYSTEM "log4j.dtd"> <log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/";> <appender name="DailyLog" class="org.apache.log4j.DailyRollingFileAppender"> <param name="File" value="logs/multiple/LoginTrack.log"/> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%d %-5p %m%n"/> </layout> </appender> <appender name="Request" class="org.apache.log4j.DailyRollingFileAppender"> <param name="File" value="logs/multiple/RequestTrack.log"/> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%d %-5p %m%n"/> </layout> </appender> <logger name="logging.request"> <level value="debug"/> <appender-ref ref="Request"/> </logger> <logger name="logging.dailyLog"> <level value="debug"/> <appender-ref ref="DailyLog"/> </logger> <root> <priority value="debug"/> </root> </log4j:configuration> In your code: // Initialize the config // DOMConfigurator.configure( "java/samples/xml/multiple/multi.xml" ); // Get the loggers // Logger requestLogger = Logger.getLogger ( "logging.request" ); Logger dailyLogger = Logger.getLogger ( "logging.dailyLog" ); // Write to the logs // requestLogger.debug( "request message1: DEBUG" ); requestLogger.info( "request message2: INFO" ); dailyLogger.debug( "dailyLog message1: DEBUG" ); dailyLogger.info( "dailyLog message2: INFO" ); You'll get two log files. I've attached the xml file and a test class.
