/**
* Simple implementation of the Quartz Job interface, applying the
* passed-in JobDataMap and also the SchedulerContext as bean property
* values. This is appropriate because a new Job instance will be created
* for each execution. JobDataMap entries will override SchedulerContext
* entries with the same keys.
*
* For example, let's assume that the JobDataMap contains a key
* "myParam" with value "5": The Job implementation can then expose
* a bean property "myParam" of type int to receive such a value,
* i.e. a method "setMyParam(int)". This will also work for complex
* types like business objects etc.
