Use my log4j under jboss 6

Question

I want to deploy my web application on JBOSS6. The applicaation itself works, but the logging doens\'t. I use log4j and have added a jboss-deployment-structure.xml to my war

Answer 1

to set my log4j in the classpath correctly i did 2 things :

1) I set the name of the log4j to use like this

-Dlog4j.configuration=fox-log4j.xml

this one has to be in the CLASSPATH

2) I call the logging manager explicitly otherwise the jboss log4j wont work

this gives in my run.conf :

#parameter used by the JVM and call later in the log4j.xml
LOG_FOLDER=$DIRNAME/../server/default/log
#jvm options
JAVA_OPTS="-Xms256m -Xmx4096m -XX:MaxPermSize=1024m -Dlog4j.configuration=fox-log4j.xml \
-Dfile.encoding=UTF-8 -Dfile.io.encoding=UTF-8 -DjavaEncoding=UTF-8 -Djboss.platform.mbeanserver \
-Djavax.management.builder.initial=org.jboss.system.server.jmx.MBeanServerBuilderImpl \
-Djava.util.logging.manager=org.jboss.logmanager.LogManager \
-Dorg.jboss.logging.Logger.pluginClass=org.jboss.logging.logmanager.LoggerPluginImpl \
-DLOG_FOLDER=$LOG_FOLDER"

now a piece of my log4j :

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/" debug="false">

 <appender name="FOX_LOG" class="org.apache.log4j.RollingFileAppender">
  <param name="Threshold" value="DEBUG"/>
  <param name="Append" value="true"/>
  <param name="MaxFileSize" value="25MB"/>
  <param name="MaxBackupIndex" value="5"/>
  <param name="File" value="${LOG_FOLDER}/fox.log"/>
  <layout class="org.apache.log4j.PatternLayout">
   <param name="ConversionPattern" value="%d{ISO8601} %-15x %t %-5p %-50.50c{1} - %m%n"/>
  </layout>
 </appender>

 <category name="com.mycompany" additivity="true">
    <priority value="DEBUG"/>
    <appender-ref ref="FOX_LOG"/>
 </category>

  <root>
    <priority value="INFO"/>
    <appender-ref ref="FILE"/>
 </root>
</log4j:configuration>

hope this could help. regards

I solved my problem doing the following: put jboss-deployment-structure.xml inside web\META-INF with the following in the file

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
  <deployment>
    <exclusions>
        <module name="org.apache.log4j" />
        <module name="org.apache.commons.logging" />
    </exclusions>
  </deployment>
</jboss-deployment-structure>

And add this to the startup of the server: -Dorg.jboss.as.logging.per-deployment=false

It means it is not loading your log4j.xml. Something wrong with the xml file location or issue with the class loader finding this log4j.xml.
