log4j - how to log to seperate/different files - jboss

Question

my application is runnig on jboss 7.3. Log4j configuration file looks
<log4j:configuration debug="true"
xmlns:log4j='http://jakarta.apache.org/log4j/'>
<appender name="fileAppender" class="org.apache.log4j.DailyRollingFileAppender">
<param name="encoding" value="UTF-8" />
<param name="append" value="true" />
<param name="file" value="${jboss.server.log.dir}/mainWS.log" />
<param name="DatePattern" value="'.'yyyy-MM-dd" />
<param name="Threshold" value="DEBUG"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%-5p %d{yyyy-MM-dd HH:mm:ss:SSS} %m rid%X{rid}%n" />
</layout>
</appender>
<appender name="File1" class="org.apache.log4j.DailyRollingFileAppender">
<param name="encoding" value="UTF-8" />
<param name="append" value="true" />
<param name="file" value="${jboss.server.log.dir}/file1.log" />
<param name="DatePattern" value="'.'yyyy-MM-dd" />
<param name="Threshold" value="DEBUG"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%-5p %d{yyyy-MM-dd HH:mm:ss:SSS} %m rid%X{rid}%n" />
</layout>
</appender>
<appender name="File2" class="org.apache.log4j.DailyRollingFileAppender">
<param name="encoding" value="UTF-8" />
<param name="append" value="true" />
<param name="file" value="${jboss.server.log.dir}/file2.log" />
<param name="DatePattern" value="'.'yyyy-MM-dd" />
<param name="Threshold" value="DEBUG"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%-5p %d{yyyy-MM-dd HH:mm:ss:SSS} %m rid%X{rid}%n" />
</layout>
</appender>
<appender name="opTimeFile" class="org.apache.log4j.DailyRollingFileAppender">
<param name="encoding" value="UTF-8" />
<param name="append" value="true" />
<param name="file" value="${jboss.server.log.dir}/opTime.log" />
<param name="DatePattern" value="'.'yyyy-MM-dd" />
<param name="Threshold" value="DEBUG"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%-5p %d{yyyy-MM-dd HH:mm:ss:SSS} %m rid%X{rid}%n" />
</layout>
</appender>
<logger name="debugLogger" additivity="false">
<level value="DEBUG" />
<appender-ref ref="fileAppender" />
</logger>
<logger name="Logger1" additivity="false">
<level value="DEBUG" />
<appender-ref ref="File1" />
</logger>
<logger name="Logger2" additivity="false">
<level value="DEBUG" />
<appender-ref ref="File2" />
</logger>
<logger name="opTimeLogger" additivity="false">
<level value="DEBUG" />
<appender-ref ref="opTimeFile" />
</logger>
<root>
<priority value="OFF" />
</root>
files are created in log directory, but loggin only performed in mainWS.log
I've tried
private static final Logger log = Logger.getLogger("debugLogger");
private static final Logger vLog = Logger.getLogger("Logger1");
private static final Logger eLog = Logger.getLogger("Logger2");
private static final Logger tLog = Logger.getLogger("opTimeLogger");
for (Enumeration loggers= LogManager.getCurrentLoggers(); loggers.hasMoreElements(); ) {
Logger logger = (Logger) loggers.nextElement();
log.debug("logger - " + logger.getName());
vLog.debug("vLogger - " + logger.getName());
eLog.debug("eLogger - " + logger.getName());
tLog.debug("tLogger - " + logger.getName());
for (Enumeration appenders=logger.getAllAppenders(); appenders.hasMoreElements(); ) {
Appender appender = (Appender) appenders.nextElement();
log.debug("appender - " + appender.getName());
vLog.debug("vAppender - " + appender.getName());
eLog.debug("eAppender - " + appender.getName());
tLog.debug("tAppender - " + appender.getName());
}
}
but result is only in mainWS.log file
DEBUG 2014-11-13 10:29:03:125 logger - rid
DEBUG 2014-11-13 10:29:03:138 logger - opTimeLogger rid
DEBUG 2014-11-13 10:29:03:138 logger - Logger1 rid
DEBUG 2014-11-13 10:29:03:138 logger - debugLogger rid
DEBUG 2014-11-13 10:29:03:138 appender - fileAppender rid
DEBUG 2014-11-13 10:29:03:139 logger - Logger2 rid
it seems that only debugLogger has an appender.
Any ideas?

Answer 1

I guess there was a conflict between log4j and the default logging implementation of the application server. I had to exclude the module from your deployment.
I added a WEB-INF/jboss-deployment-structure.xml file
<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.2">
<deployment>
<!-- Exclusions allow you to prevent the server from automatically adding some dependencies -->
<exclusions>
<module name="org.apache.log4j" />
</exclusions>
</deployment>
I had to include log4j libraries in my application classpath as well.
now it works

My first guess is that log4j reads a different config file than you expect. Check the debug output of log4j when it starts and especially the paths in there.
