title: How to log messages in a separate log file with java logging?
body: <p>I have a simple question where I still can not find any answer. I want to log messages into  a separate log file. I am using Java logging and not log4j. </p>
  
  <p>I have the following class: </p>
  
  <pre><code>package org.imixs.workflow;
  public class MailPlugin  {
   ....
        private static Logger logger = Logger.getLogger(MailPlugin.class.getName());
   ...
   logger.info("some info...");
  }
  </code></pre>
  
  <p>I am using GlassFish server. So I need to customize the settings in the logger.properties file from GlassFish. </p>
  
  <p>What entries need to be added to the GlassFish logger.properties file to log all messages from my class 'MailPlugin' into a separate log file?</p>
