How to use or.quartz.scheduler in java?

Hello,

I would like to know if there is any example that shows how to use quartz.scheduler in java, I have a textbox that show the date and another textbox that display the time, the user can choose or change the time or date and I want to pass this information to the scheduler.

 This scheduler has to run a Junit test, should be this inside of a Job class?

 Thanks in advance.
