Hi Brian, all you have to do is create a logging.properties file and  
call this before starting up solr:

System.setProperty("java.util.logging.config.file", home+"/conf/ 
logging.properties");

Your logging.properties file can look like this:

---

handlers= java.util.logging.FileHandler
# Default global logging level.
.level= INFO

# default file output is in user's home directory.
java.util.logging.FileHandler.pattern = %h/Library/Application\  
Support/Your Company/solr%u.log
java.util.logging.FileHandler.limit = 50000
java.util.logging.FileHandler.count = 1
java.util.logging.FileHandler.formatter = java.util.logging.XMLFormatter

---

And that will disable console logging. For jetty logging, you need to  
create a custom Log class that looks like this

package com.yourcompany.solr;

import java.io.IOException;

import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.solr.core.Config;
import org.apache.solr.core.SolrCore;
import org.apache.solr.schema.IndexSchema;
import org.apache.solr.servlet.SolrDispatchFilter;
import org.apache.solr.servlet.SolrServlet;
import org.apache.solr.servlet.SolrUpdateServlet;
import org.mortbay.jetty.Handler;
import org.mortbay.jetty.Server;
import org.mortbay.jetty.servlet.Context;
import org.mortbay.log.Logger;
import org.mortbay.jetty.servlet.FilterHolder;
import org.mortbay.util.DateCache;

public class NoLog implements Logger
{
    private static boolean debug = System.getProperty("DEBUG",null)! 
=null;
    private String name;

    static
    {
    }

    public NoLog()
    {
        this(null);
    }

    public NoLog(String name)
    {
        this.name=name==null?"":name;
    }

    public boolean isDebugEnabled()
    {
        return debug;
    }

    public void setDebugEnabled(boolean enabled)
    {
        debug=enabled;
    }

    public void info(String msg,Object arg0, Object arg1)
    {
    }

    public void debug(String msg,Throwable th)
    {
    }

    public void debug(String msg,Object arg0, Object arg1)
    {
    }

    public void warn(String msg,Object arg0, Object arg1)
    {
    }

    public void warn(String msg, Throwable th)
    {
    }

    private String format(String msg, Object arg0, Object arg1)
    {
        return "";
    }

    public Logger getLogger(String name)
    {
        if ((name==null && this.name==null) ||
            (name!=null && name.equals(this.name)))
            return this;
        return new NoLog(name);
    }

    public String toString()
    {
        return "NOLOG"+name;
    }

}

---

And then this before starting jetty

	System.setProperty("org.mortbay.log.class",  
"com.yourcompany.solr.NoLog");
        NoLog noLogger = new NoLog();
        org.mortbay.log.Log.setLog(noLogger);



Now, stop talking to yourself... :)
