    Default Class to run in future!

    Hello!

    I am using servlets in Web Server and I need advice on how to do something I need...

    I need to have a calendar in a servlet webpage with time and date and I need to do an action on a data and time specified by the user...

    How can I do this?? After setting the date and time what is the easiest option??

    Get the time at the moment and the future time, make the difference and run a thread till reaches 0 and then call a certain class??

    Get the future time and keep checking the current time on a thread??

    Thanks

    Hello, if I understand this correctly I'd say you should have all your actions created and then have a job/thread running on you server that checks the actions every 10 minutes or whatever your requirement might be. If an action is due to be run you run it.

    Hi!

    Thanks for your answer.

    The action I want to to is set to a certain day at a certain time.

    Example: On a webpage the user sets a day and time to do the action. At that day and time, the server executes the action. I just need to call a function.

    My doubt is how can I achieve this...

    After the user sets date and time should I start a thread?? The thread will keep checking current date and time.

    Like I said before, I think you should start a thread when you start your web application. This thread could then run all the time and every minute or so just look at the list of actions and if the current time is after the time to run the action, then run it.

    // Json

    You can use Timer API to schedule your task on time provided by the user.Timer (Java 2 Platform SE v1.4.2)
