title: java util logging configure filter in properties file
body: <p>I have a maven project where I have written a java.util.logging filter as below.</p>
  
  <pre><code>package com.xyz.filters;
  
  import java.util.logging.Filter;
  import java.util.logging.LogRecord;
  
  class CustomFilter implements Filter {
  
   public boolean isLoggable(LogRecord record) {
      return record.getLoggerName().indexOf("com.package.name") != -1;
   }
  }
  </code></pre>
  
  <p>I have a properties file in which I have configured the Console and File handlers and need to add a filter in addition to get rid of unwanted logs in the file.
  I added the filter as follows:</p>
  
  <pre><code>java.util.logging.FileHandler.filter = com.xyz.filters.CustomFilter
  </code></pre>
  
  <p>However the filter is not applied. What am I doing wrong here.</p>
  
  <p>UPDATE: Adding the configuration file</p>
  
  <pre><code>    ############################################################
  #   Default Logging Configuration File
  #
  # You can use a different file by specifying a filename
  # with the java.util.logging.config.file system property.  
  # For example java -Djava.util.logging.config.file=myfile
  ############################################################
  
  ############################################################
  #   Global properties
  #   NOTE: this configuration file use to get the handler list,
  #   Properties(except level property) define for each handler
  #   may be not available because LogRecords handover to log4j
  #   appenders in runtime.
  ############################################################
  
  # "handlers" specifies a comma separated list of log Handler 
  # classes.  These handlers will be installed during VM startup.
  # Note that these classes must be on the system classpath.
  # By default we only configure a ConsoleHandler, which will only
  # show messages at the INFO and above levels.
  #handlers= java.util.logging.ConsoleHandler
  
  # To also add the FileHandler, use the following line instead.
  #handlers= java.util.logging.FileHandler
  # Add org.wso2.carbon.bootstrap.logging.handlers.LogEventHandler to handlers if you need to push java logs to LOGEVENT appender
  
  handlers=java.util.logging.FileHandler, java.util.logging.ConsoleHandler
  
  # Default global logging level.
  # This specifies which kinds of events are logged across
  # all loggers.  For any given facility this global level
  # can be overriden by a facility specific level
  # Note that the ConsoleHandler also has a separate level
  # setting to limit messages printed to the console.
  .level= INFO
