Why RMI with Quartz?

Imagine that you need to build a job Scheduler that receives dynamic job scheduling from various client applications. In this case, a single self-contained Quartz Scheduler will not work because these client applications need a way to talk to the Scheduler from within their own address space or JVM. In this case, using something such as RMI is the only way to solve this problem.

With RMI, objects that run in one address space (or JVM) are free to call objects running in other JVMs. This expands the Quartz toolkit and makes the framework more beneficial.
