[LOGBack-user] Unable to use RollingFileAppender

[Sebastien Pennec]

Hello all,

Just a quick correction on the last sent configuration file (first example).

There was a misspelled class name that should be corrected before the config can be 
used as-is.

Here is the config file that I've just tested and that works:

<configuration>
   <appender name="bitranlog" class="ch.qos.logback.core.rolling.RollingFileAppender">
     <rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">
       <param name="ActiveFileName" value="bitran.log" />
       <param name="FileNamePattern" value="bitran.%i.log" />
       <param name="MinIndex" value="1" />
       <param name="MaxIndex" value="3" />
     </rollingPolicy>

     <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
       <param name="MaxFileSize" value="5MB" />
     </triggeringPolicy>
     <layout class="ch.qos.logback.classic.PatternLayout">
       <param name="Pattern" value="%-4relative [%thread] %-5level %class - %msg%n" />
     </layout>
   </appender>
	
   <root>
     <level value="debug" />
     <appender-ref ref="FILE" />
   </root>
</configuration>
