title: Use properties file instead of static final variables
body: <p>I have many classes with static final fields which are used as default values or config. What is best approach to create global config file? Should I move these fields to single static class, use properties file or what?</p>
  
  <p>Edit: I need to use this values both in java classes and xhtml pages. Values dosen't depend on envirnoment. I could compile project to set new values - no problem.</p>
