How to configure a separate log file(Log4j) for a specific application in JBoss?

I have modified jboss-service.xml as follows:

<mbean code="org.jboss.logging.Log4jService"
      name="jboss.system:type=Log4jService,service=Logging"
	  xmbean-dd="resource:xmdesc/Log4jService-xmbean.xml">
      <attribute name="ConfigurationURL">resource:log4j.xml</attribute>

      <attribute name="ConfigurationURL">resource:routing_log4j.xml</attribute>  
      
      <attribute name="Log4jQuietMode">true</attribute>
      <!-- How frequently in seconds the ConfigurationURL is checked for changes -->
      <attribute name="RefreshPeriod">60</attribute>
   </mbean>

I have created a file D:\Servers\jboss-4.0.5.GA\server\default\conf\routing_log4j.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">

What I am expecting is only log specific to my application will be written to my log file , but a lot of log is getting generated in my log file (routing.txt)
Where I am doing mistake, Please help in this regard
Thank you

Hi,

You will have to put log4j.jar file in your application's WAR file. Make sure that the version of log4j.jar is same as that of log4.jar available on JBoss server's lib directory. This is required, as JBoss uses log4j itself to generate it's own logs.

In fact, every Web Application requires a log4j.jar file in it's WAR so that application specific logs can be generated in separate log files.

Hope it works.

Actually, in 4.0.x you do not want to place the log4j.jar file in your WARs lib directory, it will lead to conflicts.

Here is a post from Jaikiran on how to accomplish application-level logging in 4.2.2, not sure how well it would work in 4.0.5: http://community.jboss.org/message/198691#198690

Hi M. K.,

I found that the following link was very useful in helping isolate a different log file for my web application. Basically, you would have to add your own log4J configuration (xml or properties) file in your web application, and then code a Custom RepositorySelector which would retrieve the log4J configuration from your web application, and route the logging to your own file defined in the appender that you have configured. The log file should only have logs that are specific to your web application. Please see the link below.

http://community.jboss.org/wiki/log4jrepositoryselector

Hope this helps,

Juan
