log4j can't initialize with my log4j.properties

I have a simple log4j.property file and a simple program that use log4j. But when I run my jar I see only this

log4j:WARN No appenders could be found for logger (package com.mycompany.hellolog4j).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

Here is how I use logger:

package com.mycompany.hellolog4j;

import java.io.File;
import java.io.IOException;
import org.apache.log4j.*;

public class SimpleLogging
{

    public static void main(String args[]) throws IOException {

        Logger logger = Logger.getLogger(SimpleLogging.class.getPackage().toString());
       // SimpleLogging demo = new SimpleLogging(rbName);
        //demo.doLogging(name);
        logger.info("printing the message...");
    }
}

And this is part of my pom.xml

<build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-jar-plugin</artifactId>
                <version>2.3.1</version>
                <configuration>
                    <archive>
                        <manifest>
                            <addClasspath>true</addClasspath>
                            <classpathLayoutType>custom</classpathLayoutType>
                            <mainClass>com.mycompany.hellolog4j.SimpleLogging</mainClass>
                            <customClasspathLayout>../lib/log4j.jar ../log4j.properties</customClasspathLayout>
                        </manifest>
                    </archive>
                </configuration>
            </plugin>

And here is my log4j.properties

log4j.rootLogger = DEBUG, testAppender

log4j.logger.com.mycompany.hellolog4j=DEBUG, testAppender

log4j.appender.testAppender=org.apache.log4j.ConsoleAppender

log4j.appender.testAppender.layout=org.apache.log4j.PatternLayout
log4j.appender.testAppender.layout.conversionPattern=%p-%m%n

Now from my project directory I run jar file. This is 开发者_运维问答my project directory

drwxr-xr-x 5 proger users 4096 2010-10-15 22:59 ./
drwxr-xr-x 3 proger users 4096 2010-10-15 22:27 ../

Put the log4j.properties file in src/main/resources so that it is bundled into your JAR file, and thus on the classpath.

Add this line in \weblogic\domain1\bin\setDomainEnv.cmd

set PATH=%WL_HOME%\server\native\win\x64;%PATH%
