============================================================================== This file is meant to help you get started in poking around within the Quartz project (http://www.opensymphony.com/quartz). ============================================================================== What is Quartz? ============================================================================== Quartz is an opensource project aimed at creating a free-for-commercial use Job Scheduler, with 'enterprise' features. Licensed under the Apache License, Version 2.0 (the "License"); you may not use this file except in compliance with the License. You may obtain a copy of the License at http://www.apache.org/licenses/LICENSE-2.0 Additionally, a copy of the license and its accompanying notice file is included with the distribution. Competing Products? ============================================================================== There are no known competing open source projects (there are a few schedulers, but they are basically Cron replacements written in Java) Commercially, take a look at Flux, which has many excellent features: http://www.fluxcorp.com/ What is in this package? ============================================================================== quartz-all-<ver>.jar all in one Quartz library. Includes the core Quartz components plus all optional packages. If you use this library, no other quartz-*.jars are necessary. quartz-<ver>.jar core Quartz library. quartz-jboss-<ver>.jar optional JBoss specific Quartz extensions such as the Quartz startup MBean, QuartzService. quartz-oracle-<ver>.jar optional Oracle specific Quartz extensions such as the OracleDelegate. quartz-weblogic-<ver>.jar optional WebLogic specific Quartz extensions such as the WebLogicDelegate. build.xml an "ANT" build file, for building Quartz. readme.txt this file (duh!). license.txt a document declaring the license under which Quartz can be used and distributed. src-header.txt piece of text to put at the top of each new file docs the root directory of all documentation. docs/wikidocs the main documentation for Quartz. Start with the "index.html" docs/dbTables sql scripts for creating Quartz database tables in a variety of different databases. src/java/org/quartz the main package of the Quartz project, containing the 'public' (client-side) API for the scheduler src/java/org/quartz/core a package containing the 'private' (server-side) components of Quartz. src/java/org/quartz/simpl a package contain simple implementations of Quartz support modules (JobStores, ThreadPools, Loggers, etc.) that have no dependencies on external (third-party) products. src/java/org/quartz/impl a package containing implementations of Quartz support modules (JobStores, ThreadPools, Loggers, etc.) that may have dependencies on external (third-party) products - but may be more robust. src/java/org/quartz/utils a package containing some utility/helper components used through-out the main Quartz components. src/examples/org/quartz a directory containing some code samples on the examples usage of Quartz. The first example you should look at is 'example1.bat' or 'example1.sh' - depending if you're a win-dos or unix person. This example uses the code found in the SchedTest.java class, which is also in the examples directory. webapp a directory containing a simple web-app for managing Quartz schedulers. lib a directory which should contain all of the third-party libraries that are needed in order to use all of the features of Quartz. (Some are not automatically there, but you need to get them and put them there if you use the features they depend on -- see below) Where should I start looking in order to figure this thing out? ============================================================================== There is a tutorial distributed with Quartz that can be found in the "docs" directory. You should also read the FAQ in the docs/wikidocs/ directory. Most of the Java source files are fairly well documented with JavaDOC - consider this your "reference manual". There is a tutorial and configuration reference that can be found from docs/wikidocs/index.html . Start by looking at org.quartz.Scheduler, org.quartz.Job, org.quartz.JobDetail and org.quartz.Trigger. Examine and run the examples found in the "examples" directory. If you're interested in the "behind the scenes" (server-side) code, you'll want to look at org.quartz.core.QuartzSchedulerThread, which will make you interested in org.quartz.spi.JobStore.java, org.quartz.spi.ThreadPool.java and org.quartz.core.JobRunShell. Have fun. What do I do when I find something stupid? ============================================================================== Help is available via the Quarts-Users forum: http://forums.opensymphony.com/forum.jspa?forumID=6 Please report bugs / issues to JIRA at: http://jira.opensymphony.com/browse/QUARTZ HOW TO BUILD / RUN QUARTZ ============================================================================== The current build process assumes you already have ANT version 1.6.3 or later installed. If you don't, download from the Apache website (http://ant.apache.org) and follow installation instructions. You can confirm the version of ANT you have installed by typing: ant -version To build: 1) If you are checking the project directly out of SVN, you will also need to checkout the "opensymphony" project in a parallel directory in order to get the common ANT build file: osbuild.xml 2) There should be a build.xml file located in the Quartz project root directory. 3) If you have it setup right, you should be able to type: ant It will search for build.xml in the current directory. 4) Available targets can be seen by typing: ant -projecthelp 5) To use the default build target, just type "ant" on the command line while sitting in the main 'quartz' directory.
