Quartz 1.6.5 brings you a useful scheduling system that can be integrated with, or used along side virtually any J2EE or J2SE application

Applications can vary from the largest e-commerce system to the smallest stand-alone application. Quartz can be used to create simple or complex schedules for executing tens, hundreds, or even tens-of- tousands of jobs; jobs whose tasks are defined as standard Java components or EJBs.

The Quartz Scheduler includes many enterprise-class features, such as JTA transactions and clustering.

Major Features

1. Job Scheduling:
   • At a certain time of day (to the millisecond)
   • On certain days of the week
   • On certain days of the month
   • On certain days of the year
   • Not on certain days listed within a registered Calendar (such as business holidays)
   • Repeated a specific number of times
   • Repeated until a specific time/date
   • Repeated indefinitely
   • Repeated with a delay interval
2. Job Execution:
   • Jobs can be any Java class that implements the simple Job interface, leaving infinite possibilities for the work the Jobs can perform.
   • Job class instances can be instantiated by Quartz, or by the applications framework.
   • When a Trigger occurs, the scheduler notifies zero or more Java objects implementing the JobListener and TriggerListener interfaces (listeners can be simple Java objects, or EJBs, or JMS publishers, etc.). These listeners are also notified after the Job has executed.
   • As Jobs are completed, they return a JobCompletionCode which informs the scheduler of success or failure. The JobCompletionCode can also instruct the scheduler of any actions it should take based on the success/fail code such as immediate re-execution of the Job.
3. Job Persistence:
   • The design of Quartz includes a JobStore interface that can be implemented to provide various mechanisms for the storage of jobs.
   • With the use of the included JDBCJobStore, all Jobs and Triggers configured as "non-volatile" are stored in a relational database via JDBC.
   • With the use of the included RAMJobStore, all Jobs and Triggers are stored in RAM and therefore do not persist between program executions but this has the advantage of not requiring an external database.
4. Transactions:
   • Quartz can participate in JTA transactions, via the use of JobStoreCMT (a subclas of JDBCJobStore).
   • Quartz can manage JTA transactions (begin and commit them) around the execution of a Job, so that the work the Job does happens within a JTA transaction.
5. Clustering:
   • Fail-over.
   • Load balancing.
6. Listeners & Plug-Ins:
   • Applications can catch scheduling events to monitor or control job/trigger behavior by implementing one or more listener interfaces.
   • The Plug-In mechanism can be used add functionality to Quartz, such keeping a history of job executions, or loading job and trigger definitions from a file.
   • Quartz ships with a number of "factory built" plug-ins and listeners.
7. Runtime Environments:
   • Quartz can run embedded within another free standing application
   • Quartz can be instantiated within an application server (or servlet container), and participate in XA transactions
   • Quartz can run as a stand-alone program (within its own Java Virtual Machine), to be used via RMI
   • Quartz can be instantiated as a cluster of stand-alone programs (with load-balance and fail-over capabilities)

Enhancements

• Records in QRTZ_TRIGGER_LISTENERS table are deleted when trigger is paused and resumed
• Logging Trigger History Plugin.trigger Misfired writes incorrect message
• Send Destination Message Job throws naming exception
• Send Queue Message Job throws Class Cast Exception when used with xml plugin acquire Next Trigger executing on Managed Tx Connection when using JobStoreCMT and configured not to acquire triggers within lock

eZ components 2007.2.1 is a useful program including independent building blocks for PHP application development eZ components for speeding up development and limiting risks. An application can use one or more components effortlessly as they all adhere to the same naming conventions and follow the same structure.

All components are based on PHP 5.1, except for the ones that require the new Unicode support that will be available from PHP 6 on.

The Base component provides basic functionality that all other components rely on. This basic functionality contains a certain set of exceptions and a mechanism to load components on demand, reducing memory usage. Other components build around this Base component and provide functionality for a whole range of different subjects.

Subjects include reading archive files (.zip, .tar), caching data, database SQL abstraction layer and schema management, debugging and event logging, image analysis and manipulation, in-process communication, sending fully feature mail message, templating and the safe usage of input data. Besides these main features there are also a few other components dealing with a whole range of subjects.

This is a complete list of all the individual libraries that is included in eZ components.

• Archive
• • Allows you to extract and create archive files, such as .tar (ustar, v7tar and gnutar) and .zip
• Cache
• • A solution for caching, supporting multiple backends allowing you to specify the best performing solution for your caching-problem.
• Configuration
• • A component that allows you to use configuration files in different formats.
  • The formats include the standard .ini file, and an array based format.
• ConsoleTools
• • A set of classes to do different actions with the console (also called shell). It can render a progress bar, tables and a status bar and contains a class for parsing command line options.
• Database
• • A lightweight database layer on to of PHPs PDO that allows you to utilize a database without having to take care of differences in SQL dialects.
• DatabaseSchema
• • A set of classes that allow you to extract information from a database schema, compare database schemas and apply a set of changes to a database schema.
    
• Debug
• • This components provides a set of classes that help you to debug an application. It provides timers and report generators for different formats that give a summary of warnings and errors that occurred within your application.
• EventLog
• • Allows you to log events into files or other storage spaces in different formats.
• Execution
• • Provides functionality to give feedback to your applications users when a fatal error happened or an uncaught exception was thrown.
• Feed
• • Provides reading and writing support of RSS (multiple versions) and ATOM feeds.
    
• File
• • Provides support for file operations which are not covered by PHP or are just missing.
    
• ImageAnalysis
• • This class allows you to analyse image files in different ways. At least the MIME type of the file is returned. In some cases (JPEG, TIFF and GIF) additional information is gathered as well.
• ImageConversion
• • A set of classes to apply different filters on images, such as colour changes, resizing and special effects.
• Mail
• • The components allows you construct Mail messages conforming to the RFCs. It has support for attachments, multipart messages and HTML mail. It also interfaces with SMTP to send the e-mail. Reading and parsing mail messages comes in version 1.1.
• PersistentObject
• • This component allows you to store an arbitrary data structures to a fixed database table. The component provides all the functionality needed to fetch, list, delete etc these datastructures.
• PhpGenerator
• • Provides a simple interface for creating PHP files and executing PHP code.
• SystemInformation
• • Provides access to common system variables, such as CPU type and speed, and the available amount of memory.
    
• Template
• • A fully functional Templating system, supporting template compilation in different levels, user defined functions and operators, an optimizer, output escaping for different output handlers to prevent XSS and other security problems and a plug in system for extra functionality (such as a Translation system).
    
• Translation
• • A component that reads XML translation definitions (the Qt Linguist format), supports caching of translation contexts and presents you with a class to apply translations to strings. A filter system allows you to transform translation definitions for special use.
• Url
• • Provides functionality for parsing URL parameters, and path manipulation.
• UserInput
• • A component that assists you to safely user input variables coming into your application. It builds on top of PHPs filter extension and extends it by providing a more inituitive API.
