Help needed in Logging

Question

Hi,
I have created a custom logging Handler and configured the same in the properties file. This handler has its own Formatter and Filter. When I iterate through the LogManager and print the available Handlers I get a NullPointerException when it prints the Formatter assoicated with the Custom Handler.
Properties File
com.test.logging.CustomHandler.pattern = %h/java%u.log
com.test.logging.CustomHandler.formatter = com.sabre.logging.CustomFormatter
com.test.logging.CustomHandler.filter = com.sabre.logging.CustomFilter
com.test.logging.CustomHandler.level = INFO
CustomFormatter class is in the right package.
Iterator Code..
for (;loggerNames.hasMoreElements();) {
               String loggerName = loggerNames.nextElement();
               System.out.println("Logger Name is : "+ loggerName);
               Logger logger = Logger.getLogger(loggerName);
               Handler[] handlers = logger.getHandlers();
               logger.setUseParentHandlers(false);
               for(int i=0;i<handlers.length;i++){
                    System.out.println("Handler : "+handlers.toString());
                    System.out.println("Pattern :" +handlers[i].getEncoding());
                    System.out.println("Level : "+ handlers[i].getLevel().getName());
                    // Filter cannot be printed. Donno the Reason
                    if(handlers[i].getFilter()!=null)
                         System.out.println("Filter : "+ handlers[i].getFilter().toString());
                    System.out.println("Formatter : "+ handlers[i].getFormatter().toString());
               }// End For Loop
          } // End Outer For Loop
I donno what is wrong with this.. Help me in resolving this..
Thanks in advance

public static void main(String[] args) throws SecurityException, FileNotFoundException, IOException {
          LogManager logManager = LogManager.getLogManager();
          logManager.readConfiguration(new FileInputStream("logging.properties"));
          Enumeration<String> loggerNames = logManager.getLoggerNames();
          for (;loggerNames.hasMoreElements();) {
               String loggerName = loggerNames.nextElement();
               Logger logger = Logger.getLogger(loggerName);
               Handler[] handlers = logger.getHandlers();
               for(int i=0;i<handlers.length;i++){
                    System.out.println("Handler : "+handlers.toString());
                    System.out.println("Level : "+ handlers[i].getLevel().getName());
                    System.out.println("Filter : "+ handlers[i].getFilter().toString());
                    System.out.println("Formatter : "+ handlers[i].getFormatter().toString());
               }// End For Loop
          } // End Outer For Loop
     } // End Main
Here it is...
