Forewarning: I am new to log4j logging and well logging in general and apologize for my ignorance.
When ever I run my program from a .jar I get a “jackrabbit.log_IS_UNDEFINED” file in the directory where my program was ran. This log file is Extremely large(300MB+) and filling up my drive. I can see that this file has DEBUG level logs in it from several different libraries that I am using. I wish to rid myself of this “jackrabbit.log_IS_UNDEFINED” file and log only ERROR level logs or above to my own file on another drive. eg. (/smb01/Aggregator.log).
Any Help would be Greatly Appreciated.
Also when I run the jar from the command line I get a Log4j Error:
log4j:ERROR Root level cannot be inherited. Ignoring directive.
I do want/have to specify my own config file so we can log our own errors.
I have inherited this config file.

Since this is for my work I cant share all of my code but here are the key bits:
import org.apache.log4j.xml.DOMConfigurator;
import org.apache.log4j.*;
import org.apache.log4j.Logger;
public class Main {
public static Logger logger = Logger.getLogger("com.group.main");
public static void main(String[] args) {
// setup the log4j system so we can log stuff.
org.apache.log4j.extras.DOMConfigurator.configure(args[1]);
.
.
logger.debug("debug message!");
.
.
.
}
The files Aggregator.log and CustomerReport.csv do Show up where they are supposed to but nothing is logged/written to them. I have been able to look at the “jackrabbit.log_IS_UNDEFINED” file and it has all of my logging in it.
Libraries that deal with log4j that i’m using(listed via build path order):
- log4j-1.2.17.jar
- apache-log4j-extras-1.1.jar
- jackrabbit-standalone-2.2.10.jar
More Info
I found another xml file with what appears to be my culprit: logback.xml
<configuration>
<appender name="jackrabbit" class="ch.qos.logback.core.FileAppender">
<file>${jackrabbit.log}</file>
<encoder>
<pattern>
%d{yyyy-MM-dd HH:mm:ss.SSS} %-5level %-40([%thread] %F:%L) %msg%n
</pattern>
</encoder>
</appender>
<appender name="jetty" class="ch.qos.logback.core.FileAppender">
<file>${jetty.log}</file>
<encoder>
<pattern>
%d{yyyy-MM-dd HH:mm:ss.SSS} %-5level %-40([%thread] %F:%L) %msg%n
</pattern>
</encoder>
</appender>
<logger name="org.mortbay.log" level="${log.level}" additivity="false">
<appender-ref ref="jetty"/>
</logger>
<root level="${log.level}">
<appender-ref ref="jackrabbit"/>
</root>
</configuration>
Can I (edit/remove/workaround) this file?
I ended up not using jackrabbit-standalone-2.2.10.jar which eliminated the error altogether. Instead I imported only specific classes from various other libraries included in CQ 5.4.
I Still have the same setup as shown above except for the jackrabbit-standalone-2.2.10.jar.
@TedTrippin, Thank you for your time and consideration.
