Jboss-log4j.xml configuration

vinayarammohan1 Jun 5, 2009 5:00 PM

Hi,

I am using Jboss 4.2.2GA
I am fine when I have log4j.properties file. But I want to switch to jboss-log4j.xml. I wanted to go with this because, this file can be hot deployed.

When trying to do this, I am getting the following error

16:50:32,765 ERROR [STDERR] log4j:ERROR A "org.jboss.logging.appender.FileAppender" object is not assignable to a "org.apache.log4j.Appender" variable.
16:50:32,765 ERROR [STDERR] log4j:ERROR The class "org.apache.log4j.Appender" was loaded by

16:50:32,765 ERROR [STDERR] log4j:ERROR Could not instantiate appender named "FILE".

My jboss-log4j.xml is









Is there any thing wrong with my file?

Thanks in Advance
Vinaya

Where did you place this file?

By the way, when posting XML code, wrap it in "code" tags. To do this, select the text and click the Code button above the editor window. Also, click Preview and verify the formatting before clicking Submit.

Hi Peter,
I have the file in
jboss_home/servers/default/config, my app is in default folder.

My Xml is

 <appender name="FILE" class="org.apache.log4j.FileAppender">
 <errorHandler class="org.jboss.logging.util.OnlyOnceErrorHandler"/>
 <param name="File" value="C:/jboss-4.2.2.GA/server/default/log/server.log"/>
 <param name="Append" value="false"/>
 <param name="Threshold" value="DEBUG"/>
 <param name="Encoding" value="UTF-8"/>
 <!-- Rollover at midnight each day -->

 <!-- Rollover at the top of each hour
 <param name="DatePattern" value="'.'yyyy-MM-dd-HH"/>
 -->

 <layout class="org.apache.log4j.PatternLayout">
 <!-- The default pattern: Date Priority [Category] Message\n -->
 <param name="ConversionPattern" value="%d [%X{username}] %-5p [%c] %m%n"/>

 <!-- The full pattern: Date MS Priority [Category] (Thread:NDC) Message\n

Do you have a copy of log4j.jar in you app? If so, remove it.

Hi Peter,

I tried that. But I have using Log4jMDCUserFilter to log the session id and user name. I am getting errors on this , if I remove the log4j.jar.

Thanks
