Regarding sheduler concept in J2EE

Hi all,

My requirement is to fetch data from a DB at one server to DB at another Server.I have to do this 2 or e times a day.For this purpose i am thinking as below....

Running a servlet for this task with neccessary implementation basing on the systemdate.

Is there any other way to implement this task.

I heard about scheduler concept in J2EE.

But i don't know the implementation.

Any one please give me guidance in this issue.

Thanks&Regards
