Created a new Quartz based version of the HttpMonitor class by extension with various refactors of the superclass. Removed the private visibility modifier from several constants so they are accessible to the subclass. Created a simple no-arguments constructor for HttpMonitor to conform to the requirements of Quartz through its subclass. The constructor declares an anonymous inline class for the DAOLog variable that actually logs to the System.out stream. Also created a public Set getUrlKeySet() method to acquire the URLs to check from the superclass Map.
The QuartzHttpMonitor class extends HttpMonitor and implements the Quartz Job interface with an execute(JobExecutionContext) method that calls a separate checkUrl() adapted from the superclass checkUrls() method. The execute method stores an array of URLs passed by the JobExecutionContext's JobDataMap store. A private static counter variable is used to cycle through the URLs in the array on the given schedule.
A QuartzTest class loads the URLs to check from a Java properties file, creates the JobDataMap, job CronTrigger and sets the Scheduler for requests based on a command line parameter. Both the QuartzTest and QuartzHttpMonitor classes declare a Logger instance and have detailed debug and information log calls throughout. The Log4J configuration QuartzLog.properties logs program information messages to the console, error messages are also sent by email using an SMTPAppender.

Added the Quartz JAR file and Apache Log4J to the Ant compilation target and created a Windows batch file to launch the scheduler, configured with a set of Code Style RSS news feed URLs to check one at a time each 20 minutes.

Changed the scheme for premium content subscriptions to set your own price and updated the "Why pay ..." includes. Removed the FAQ by email option from all premium content links and standfirst references. Added a new section "Preliminary answer" sub-heading before premium FAQ stub answers for clearer separation from the standfirst. Created an overloaded version of the printPremiumContentLink() method for premium stub articles to customise the "subscribe now" call to action and link to point to the sign-up form on the same page.Re-generated all FAQ content.
Checked in friendly redirects for forthcoming applet object eBook and premium content subscription page.
