In this section we will download Quartz Job Scheduler from its distribution web site and then create development environment in the eclipse integrated development environment.
Downloading Quartz Job Scheduler
Quartz is an open source enterprise grade software for the development of Job Scheduling application in java. Quartz Scheduler is from OpenSymphony which can be downloaded from http://www.opensymphony.com/. At the time of writing this tutorial the latest version of Quartz Scheduler is 1.6.0. You can download the latest version of software and then try. For this tutorial we have downloaded quartz-1.6.0.zip.
After downloading the zip file extract it and you will find the following directory in the extracted directory.
Here is the description of files and directories:
|quartz-all-<ver>.jar||Quartz library includes the core Quartz components and all optional packages. If you are using this library then no other quartz-*.jars need to include.|
|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
|quartz-weblogic-<ver>.jar|| optional WebLogic specific Quartz extensions such
as the WebLogicDelegate
|build.xml||an "ANT" build file, for building Quartz.|
|docs||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|| this package contains simple implementations of
Quartz support modules (JobStores, ThreadPools,
Loggers, etc.) that have no dependencies on external (third-party) products.
|src/java/org/quartz/impl|| this package contains 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||this package contains some utility/helper components used through-out the main Quartz components.|
|src/examples/org/quartz||this directory contains some examples usage of Quartz.|
|webapp|| this directory contains
a simple web-app for managing
|lib||this directory contains all third-party libraries that are needed to use all of the features of Quartz.|
Setting Up Development project in Eclipse
Run the eclipse IDE and create new java project. From the file menu select --> New --> Project
New Project dialog box displayed as follows:
Select "Java Project" and click on the "Next >"
Enter "Quartz Project" in the Project Name text box and click on the "Finish" button to create the project. A new project is created and following screen is displayed.
Adding required quartz libraries to the project
Copy the lib directory and all the jar files from the unzipped directory and then paste into the eclipse project (Ctrl +C and Ctrl +V).
Open the project property and then add all the jar files into the build path as shown below.
and then click on the "OK" button.
Now your development environment is ready for the development. In the next section we will develop a simple scheduler application that prints "Hello Quartz Scheduler" on the console at particular time interval.
