title: My logging.properties custom formatter is not working
body: <p>I'm actually adding java logging (can't use other framework) to my project. I build my app on a .war, and deployed it over Weblogic, the logger is working with my logging.properties config, except for the formatter i don't know why the app is ignoring it.</p>
  
  <p>This is my class where i prepare the logger;</p>
  
  <pre><code>public class CtgLogger {
  private static final String LOAD_ERROR = "Properties could not be loaded.";
  
  private static final Map&lt;String, Level&gt; LEVEL_MAP;
  private static final Logger LOGGER = Logger.getLogger(Logger.GLOBAL_LOGGER_NAME);
  static {
  
      final InputStream inputStream = CtgLogger.class.getResourceAsStream("/logging.properties");
      try {
          LogManager.getLogManager().readConfiguration(inputStream);
      } catch (Exception e) {
          Logger.getAnonymousLogger().severe(LOAD_ERROR);
          Logger.getAnonymousLogger().severe(e.getMessage());
      }
      // and I add the LEVEL_MAP to the logger...
  </code></pre>
  
  <p>And this is my properties...</p>
  
  <pre><code>handlers = java.util.logging.FileHandler
  java.util.logging.FileHandler.pattern=logsfolder/CTGLOG_%g.log
  java.util.logging.FileHandler.level=ALL
  java.util.logging.FileHandler.limit=3000
  java.util.logging.FileHandler.count=6
  #java.util.logging.FileHandler.formatter=java.util.logging.SimpleFormatter
  #If I use the SimpleFormatter, apps goes well with it format. 
  java.util.logging.FileHandler.formatter = com.package.my.log.JsonCustomFormatter
  #If I use my custom formatter, the weblogic works with a XMLFormatter (default)
  </code></pre>
  
  <p>I know the .properties is working, because logger is working with the pattern, limit and count I setted.</p>
  
  <p>PD: If i run my app with JUnit, logs are working with my custom formatter, but do not at weblogic! Don't know why!</p>
