This works for JDK-logging:

package org.apache.plugins;

import java.util.logging.Logger;
import org.apache.catalina.valves.AccessLogValve;

public class AccessLogJdkValve extends AccessLogValve {

    private static Logger jdkLogger = Logger.getLogger(AccessLogJdkValve.class.getName());

    @Override
    public void log(String msg) {
        jdkLogger.info(msg);
    }

    @Override
    protected synchronized void open() {
        // do nothing
    }
}

pom.xml

    4.0.0
    tomcat7-conf
    tomcat7-conf
    1.0-RELEASE
    jar

    
        
            org.apache.tomcat.maven
            common-tomcat-maven-plugin
            2.2
        
        
            org.apache.tomcat
            tomcat-catalina
            7.0.12
        
    

    
        src
        
            
                maven-compiler-plugin
                3.3
                
                    1.8
                    1.8
                
            
        
    

Just compile, make a jar, put a copy in /usr/share/tomcat7/lib/, and modify server.xml. I added it to my reference tomcat7 configuration on github.
