Added a Hashtable to the new draft XSL ResultCache to store the cache, and added Serializable declarations to Parameters and ResultKey to enable the Hashtable to be saved and loaded. Added addResult, getResult, deleteResult, and hasResult methods to manage ResultKeys, an emptyCache method, a public save method and private load method to deserialize the cache when the class is loaded.
Created a first skeleton draft of ResultValue and updated ResultCacheTest to test all new methods.

Added new executeInsert, executeDelete, getQueryDatum and getKeyDatum convenience methods with basic error checking. Also added boolean isSingleRow, isSingleColumn, isSingleDatum methods to the DBResults class.

Added Opera 7.50, Firefox 0.8.0+, Firefox 0.8 and Galeon versions 1.3.7 and 1.3.11a to the validation script for the Code Style font survey. There were an exceptional number of submissions this week thanks to referrals from Dive Into Mark, Mezzo Blue and Zeldman, so a special update to the results pages was compiled and issued.
Adjusted the minimum results limit on the draft FontStats servlet to zero, to build the full combined font survey results table directly. The zero value equates to no SQL LIMIT statement.
Added an SQL ORDER statement to the font survey submissions per month query, and modified the surveyline table to include the Bitstream Vera font images in the Unix family font survey results.

Adapted the ParseRSS class to implement a new ParseFAQ transformation servlet.

Also had to update the SourceBrokerFactory to acquire a FileBroker for the source. Deployed the first draft faq.dtd and added it to the local ResourceResolver Hashtable.
Updated the remote Ant filter files for the Code Style build to include the new ParseFAQ stylesheet file name in the servlet configuration.
