I am having trouble getting slf4j/logback to work in my webapp that is getting deployed in Tomcat. I have changed all of my application classes to import and use the slf4j classes, I compile with them and then deploy a war that Tomcat expands into the webapp dir. My logback.xml file shows up in the WEB-INF/classes directory of my application but no log file gets created/written to. I used the log4j Properties translator page to get this xml: <?xml version="1.0" encoding="UTF-8"?> <configuration> <appender name="F" class="ch.qos.logback.core.rolling.RollingFileAppender"> <File>${catalina.base}/logs/srvc2.log</File> <layout class="ch.qos.logback.classic.PatternLayout"> <pattern>%d{dd MMM yyyy HH:mm:ss} %c{3}:%L - %m%n</pattern> </layout> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <fileNamePattern>'.'yyyy-MM-dd</fileNamePattern> </rollingPolicy> </appender> <logger name="com.opensymphony.oscache"> <level value="ERROR"/> </logger> ... in here there a bunch more logger elements that set the level for various things. <logger name="com.vizible"> <level value="DEBUG"/> </logger> <root> <level value="INFO"/> <appender-ref ref="F"/> </root> </configuration> I am expecting to see a file in the Tomcat logs directory called "srvc2.log" but I don't see anything and none of the regular Tomcat logs show anything. I am running Tomcat as a service in windows XP. Am I missing something?? Any suggestions would be appreciated. -- View this message in context: http://www.nabble.com/logback.xml-with-Tomcat-5.5-tf4713692.html#a13474065 Sent from the Slf4J - user mailing list archive at Nabble.com. -- View this message in context: http://www.nabble.com/logback.xml-with-Tomcat-5.5-tf4714034.html#a13475065 Sent from the Logback User mailing list archive at Nabble.com.
