Your root looger defines debug logging for all components. You should change it to warn (so you still see warnings) and add an extra logger for your own components:
<logger name="com.xxx.mycomponent">
<level value="trace"/>
<!-- appenders ... -->
</logger>
<root>
<priority value="warn" />
<appender-ref ref="console" />
<appender-ref ref="dailyrollinglogfile" />
</root>


Simply turn off the logging for the package you don't want to see in your logs...
<!-- Limit JBoss categories -->
<category name="org.jboss">
<priority value="OFF"/>

Disable level log log4j

I have errorAppender and infoAppender to separate in 2 log files.
That is working, but I need to log in info file only info information.
Example:
when I call logger.error("TEST ERROR"), I don't want this showing on info file.
is there any way to disable level logs?

Log4j disabling console logging

I need to make logger that will only log to file, but when I set XML likie this:
<appender name="file" class="org.apache.log4j.RollingFileAppender">
<param name="append" value="false" />
<param name="maxFileSize" value="1MB" />
<param name="maxBackupIndex" value="5" />
<param name="file" value="${SERVER_HOME}/logs/mylog-log.txt" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n" />
</layout>
</appender>
<logger name="com.packageforlogging" additivity="true">
<level value="DEBUG" />
<appender-ref ref="file" />
</logger>
It stills logs into console, because there are other loggers to which i don't have access. How I can do it?

This is just a log4j issue. It appears that <priority> is not a valid sub-element of the logger element <root>. Rather, you should have <level> instead.
