java - Log4j 2: How to Use XMLLayout? -



java - Log4j 2: How to Use XMLLayout? -

the log4j 2 manual states:

an appender uses layout format logevent form meets needs of whatever consuming log event.

among several of appenders in log4j2.xjm, have this:

<rollingfile name="rollingratefile" filename="${sys:webapp.rollinglogspath}/${sys:webapp.name}.rate.log" filepattern="${sys:webapp.rollinglogspath}/${sys:webapp.name}.log-%d{yyyy-mm-dd}-%i.rate.log"> <patternlayout> <pattern>%d{yyyy-mm-dd hh:mm:ss.sss} %m%n</pattern> </patternlayout> <policies> <sizebasedtriggeringpolicy size="10 mb" /> </policies> <defaultrolloverstrategy min="1" max="4" /> <xmllayout complete="true" charset="utf-8" compact="false"/> </rollingfile>

when tomcat starts, error:

2014-11-06 12:45:40,631 error appender rollingfile has no parameter matches element xmllayout 2014-11-06 12:45:40,696 error appender rollingfile has no parameter matches element xmllayout

logging standard log file works great when omit xmllayout element. can't seem locate examples of how correclty utilize xmllayout. know i'm doing wrong?

it turns out patternlayout mutually exclusive xmllayout. when patternlayout removed, xmllayout works.
