Spring, Log4j within web application

I'm trying to use log4j

my log4j.propreties:

log4j.rootLogger=DEBUG, out

log4j.logger.org.springframework=INFO
log4j.logger.org.apache.activemq=INFO
log4j.logger.org.apache.activemq.spring=WARN
log4j.logger.org.apache.servicemix=DEBUG, stdout

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} | %-5p | %t | %c | %m%n

log4j.appender.out=org.apache.log4j.DailyRollingFileAppender
log4j.appender.out.DatePattern=?-?yyyy-MM-dd?.log??/>
log4j.appender.out.layout=ConversionPattern %d{ABSOLUTE} | %-5p | %t | %c | %m%n
log4j.appender.out.file=/home/adam/workspace/log/servicemix

part of web.xml

        <load-on-startup>1</load-on-startup>
    </servlet>
...
</web-app>

I added dependencies:

    <dependency>
        <groupId>log4j</groupId>
        <artifactId>log4j</artifactId>
        <version>1.2.16</version>
    </dependency>
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-log4j12</artifactId>
        <version>1.5.2</version>
    </dependency>

But I'm getting errors:

Should I add any other dependencies related with log4j?

You are getting error as you are trying to initialize Log4jConfigListener after initializing ContextLoaderListener. Log4jConfigListenere should be initialized before ContextLoaderListener. I hope this answer helps you..

One other minor point is that the Log4JConfigListener should be registered before the ContextLoaderListener. They are in reverse order above.

See http://static.springsource.org/spring/docs/3.0.x/javadoc-api/org/springframework/web/util/Log4jConfigListener.html

This doesn't appear to have impacted things in this particular case, but perhaps this tip might be useful for somebody else stumbling upon this!

Within your log4j.properties, in the log4j.appender.out section:

log4j.appender.out.layout=ConversionPattern %d{ABSOLUTE}

Should be:

log4j.appender.out.layout.ConversionPattern=%d{ABSOLUTE}
