I have a requirement of creating files and sending mails from my java application based on some conditions like ,the user selects the date and time from the UI and fills the details.on that particular date and time i need to create a file and trigger a mail with the filled in details.
how can i do this.

There are several ways to do this, but they depend on what operating system you are using.

If you are using Linux, then you could use CRON to schedule a job (Java executable code) that would run, say, once a minute. It could look in the DB to see what is scheduled for that date and time and perform the operations. On Windows, you could do the same thing with the task manager.

You COULD even have the CRON job execute JSP code (say a servlet), but there's no real need to use JSP for this on the "back end."
