Configuration of Quartz is typically done through the use of a properties file, in conjunction with the use of StdSchedulerFactory (which consumes the configuration file and instantiates a scheduler).

By default, StdSchedulerFactory load a properties file named "quartz.properties" from the current working directory. If that fails, then the quartz.properties file located (as a resource) in the org/quartz package is loaded. To us e a file other than these defaults, you must define the system property org.quartz.properties to point to the file you want.

Alternatively, you can explicitly initialize the factory by calling one of the initialize() methods before calling getScheduler() on the StdSchedulerFactory.

Instances of the specified JobStore, ThreadPool, and other SPI classes will be created by name, and then any additional properties specified for them in the config file will be set on the instance by calling an equivalent 'set' method. For example if the properties file contains the property org.quartz.jobStore.myProp = 10, then after the JobStore class has been instantiated the method setMyProp() will be called on it. Type conversion to primitive Java types (int, long, float, double, boolean, and String) are performed before calling the property's setter method.

One property can reference another property's value by specifying a value following the convention of $@other.property.name. For example, to reference the scheduler's instance name as the value for some other property, you would use $@org.quartz.scheduler.instanceName.
