Hi,
I am new to Quartz and I have some questions .
as far as I know scheduler.start actually create instance of jobclass and then invoke execute method of it , is their any way where i can pass instance of job class instead of Class reference.

I want to avoid too many instance creation of my class because I want to add several method of that class in job .

What I meant is

Class Node implements Job {

public void execute(.....) {
}
}

Class Test {

public static void main(String arg[]){
JobDetail jd = new JobDetail(Node.class);

Sched.start() ----------------------------> will create one instance per jobDetail

}

}

Now when I will pass

You may be interested in implementing your own JobFactory and specifying Quartz use it within your quartz.properties.

any example where I can see how do I write my own JobFactory class

There are a couple in Quartz's code base, and at least one in Spring's code base.

I don't know of any written/guided example.

It's rather easy though: just implement the simple JobFactory interface to produce your instance (or hand a recurring instance to Quartz), then set one line of config in your Quartz properties to name your job factory class.

Code:

 org.quartz.scheduler.jobFactory.class: com.foo.MyJobFactory
