Help required on Quartz Scheduler

Hi,

I need help on Quartz Scheduler.
I have web appliction with spring framework. I integarte quartz scheduler with spring framework. I am using method invoking job feature so I have one bean class with different methods which I want to schedule. I wrote xml mapping of scheduler in applicationContext.xml so my scheduler is starting with tomcat server.

Is it ok to integrate scheduler with my main web application or should I write separate application for scheduler?

how to stop on of the job running by scheduler?
