How to start selenium server with log4j

I want to start selenium server with log4j so that all server related logs go there. I'm starting the server with ANT using the following ANT target

<target name="startserver" depends="setClassPath">
 <java jar="${test.home}/lib/selenium-server-standalone-2.20.0.jar"  fork="true">
 <arg line="-Djava.util.logging.config.file=log4j.properties"/>
 <arg line="-firefoxProfileTemplate 'D:\selenium.default'"/>
 <arg line="-browserSideLog"/>
 </java>
 </target>    
 

My log4j.properties is as below:

log4j.rootLogger=INFO, R, stdout
 
 log4j.appender.R=org.apache.log4j.RollingFileAppender
 log4j.appender.R.File=./logs/sellog.log
 log4j.appender.R.MaxFileSize=10MB
 log4j.appender.R.MaxBackupIndex=1
 log4j.appender.R.layout=org.apache.log4j.PatternLayout
 log4j.appender.R.layout.ConversionPattern=%5p [%t] (%F:%L) - %m%n
 
 log4j.appender.stdout=org.apache.log4j.ConsoleAppender
 log4j.appender.stdout.Target=System.out
 log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
 log4j.appender.stdout.layout.ConversionPattern=%5p [%t] (%F:%L) - %m%n
 

But I'm not getting any server logs after I start the server from the target.

Also, I have a selenium test where I'm throwing the log into log4j as below:

private LogManager lm;
 private Logger logger = lm.getLogger(this.getClass().getName());
 logger.info("Selenium Client started...");
 

I'm getting application logs in log4j log.

What I want is to have all the logs (selenium server log + app log) in log4j log.

Any help is greatly appreciated.
