Cast Java Map to ConcurrentMap

I couldn't find a quick and easy example of this on Google, so here you go:

Using Google Guava:

Map<String, String> map;
ConcurrentMap<String, String> ccMap = new MapMaker().weakKeys().weakValues().makeMap();
ccMap.putAll(map);

Simple & Stupid Logger for Java

Since I cannot find a logger easy enough for me to use, I made one.

The jar file is here: linky

This logger is thread safe.

Example usage in a servlet:

package com.logtest;

import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletConfig;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import log4andrew.Logger;
import log4andrew.LogLevel;

/**
 * Servlet implementation class Test
 */
@WebServlet("/Test")
public class Test extends HttpServlet {
    private static final long serialVersionUID = 1L;
    private static String filePath = "";
    private static String fileName = "";
    Logger fLogger = null;
    final static String FS = File.seperator;
    /**
     * @see HttpServlet#HttpServlet()
     */
    public Test() {
        super();
    }
   
    @Override
    public void init(ServletConfig config){
        ServletContext scxt = config.getServletContext();
        filePath = scxt.getRealPath("WEB-INF") + FS + "logs" + FS;
        fileName = "servletTest";
        fLogger = new Logger(filePath, fileName, LogLevel.INFO);
    }

    /**
     * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
     */
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        PrintWriter out = response.getWriter();
        out.println("file location: " + filePath + fileName);
        fLogger.critical("some message");
        out.println("debug message logged");
    }

    /**
     * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
     */
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        doGet(request, response);
    }

}
