Java Scheduler - help in designing

Hi Folks,
First of all I do not know if this I am in the right form, if it is not then I apologize and please direct me to the right one.

Here's my requirement: I need a Java Scheduler. Something that is supposed to check the database every minute (that sounds expensive to me, would love your inputs) and see if there are any jobs for that minute.
And if there is a job to be run that minute, get the information pertinent to executing the job and add the job to a queue. This job will be delegated to a worker that will have its own thread and will run the job.
I did some research and saw the Quartz framework.
Now my questions:
*I was given this requirement. For the domain I am on, I do not think I need a task to be hitting the database every minute and check for a job.

*If it is not a big deal to do it in this way, can i use Quartz in some fashion?

*If not for this solution or Quartz, what is the best way to execute this need. Wherein an administrator will go in and add tasks and the time in the database and will expect the application to fire it at that instant.

I know I've given a very long question. I could not help it; I needed to get a validation on the design and see if some of you gurus can help me with a sound solution.

Thanks for all your help.

Thanks ... Raghu
