I add these code below to log4j.xml,but it won't work ! appender name="web1" class="org.jboss.logging.appender.DailyRollingFileAppender" ...................... param name="File" value="${jboss.server.log.dir}/web1.log" .................... /appender category name="mypackagename" additivity="false" priority value="INFO" / appender-ref ref="web1"/ /category All of the two web module use the package "mypackagename",so i mean to use this newly added category and appender to meet my need,but the output is utterly disorderly.
