while running jboss server it gives error for org.jboss.logging.util.OnlyOnceErrorHandler

[Abhishek Mhptr]

Hi.

i have created an log4j.xml file inside jboss/server/default/config. (this file is different than jboss-log4j.xml)

here is the content of my log4j.xml file.

  
<?xml version="1.0" encoding="UTF-8"?>

   |
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/" debug="false">

 
 <appender name="FILE" class="org.apache.log4j.RollingFileAppender"> 
 	<errorHandler class="org.jboss.logging.util.OnlyOnceErrorHandler"/>
	<param name="File" value="${jboss.server.home.dir}/log/g2sHost.log"/> 
	<param name="MaxFileSize" value="5MB"/>
	<param name="MaxBackupIndex" value="3"/>
	<layout class="org.apache.log4j.PatternLayout"> 
		 <param name="ConversionPattern" value="%d{HH:mm:ss,SSS} %-5p (%t: %x) %c{1}.%M - %m%n"/> 
	 </layout> 
 </appender> 	

	<appender name="CONSOLE" class="org.apache.log4j.ConsoleAppender">

		<param name="Target" value="System.out"/>
		<layout class="org.apache.log4j.PatternLayout">
			<!-- The default pattern: Date Priority [Category] Message\n -->
			<param name="ConversionPattern" value="%d{HH:mm:ss,SSS} %-5p (%t: %x) %c{1}.%M - %m%n"/>
		</layout>
	</appender>       
	
	<category name="org.apache.commons">
		<priority value="INFO"/>
	</category>
	
	<category name="org.jboss">
		<priority value="INFO"/>
	</category>	

	<logger name="com.example.log" additivity="false">
		<level value="DEBUG"/>
		<appender-ref ref="FILE"/>
	</logger>

	<root>
		<level value="ERROR"/> 
		<appender-ref ref="CONSOLE"/>
		<appender-ref ref="FILE"/>
	</root>

</log4j:configuration>

it works fine. but it gives the following error in the console while running the jboss server.

20:09:31,727 ERROR [STDERR] log4j:ERROR A "org.jboss.logging.util.OnlyOnceErrorHandler" object is not assignable to a "org.apache.log4j.spi.ErrorHandler" variable.

i have gone through many forums and articles. everyone has suggested to remove log4j.jar file from the WEB-INF/lib folder.
but if i do that i am unable to get the output.

kindly help me out in getting rid of the error messages without removing the jar file as we need that for our application..

thanks in advance.

Why not just add your appenders and categories to jboss-log4j.xml?

Or perhaps this will help: http://www.jboss.org/community/wiki/ScopedLoggingConfig
