Question

I am using the default java.util.Logging API to print information to my log.

Logger.getLogger(Datastore.class.getName());
logger.info("Registering ");

where Datastore is the name of the class.But I am unable to find where the logs are stored. I am running on a Windows 7 machine and the above program is a part of a servlet. I apologize for the seemingly stupid question, but sometimes such insignificant things greatly hinder progress.

By default the java.util.logging.Logger sends output to the console and aren’t printed to a file. You will have to add a java.util.logging.Handler to the Logger.
Below are snippets to create Handlers of HTML, TEXTFILE. Hope this helps.

package logging;

import java.io.IOException;
import java.util.logging.FileHandler;
import java.util.logging.Formatter;
import java.util.logging.Level;
import java.util.logging.Logger;
import java.util.logging.SimpleFormatter;

public class MyLogger {
    static private FileHandler fileTxt;
    static private SimpleFormatter formatterTxt;

    static private FileHandler fileHTML;
    static private Formatter formatterHTML;

    static public void setup() throws IOException {
        // Create Logger
        Logger logger = Logger.getLogger("");
        logger.setLevel(Level.INFO);
        fileTxt = new FileHandler("Logging.txt");
        fileHTML = new FileHandler("Logging.html");

        // Create txt Formatter
        formatterTxt = new SimpleFormatter();
        fileTxt.setFormatter(formatterTxt);
        logger.addHandler(fileTxt);

        // Create HTML Formatter
        formatterHTML = new MyHtmlFormatter();
        fileHTML.setFormatter(formatterHTML);
        logger.addHandler(fileHTML);
    }
}
