Keep Application Running

[sergio.bessa@xxxxxxxxxxx]

Hi, I need help acomplishing the following:

1 - Have an application which does something in background
    Example: Calculate primes -> PrimeCalculator extends Runnable

2 - Have a web page to see discovered primes
    PrimePresentation implements HttpPresentation

I want the application 1 to keep running and the new results to be seen the 
next time the user refreshes the web page.


Thanks for any help
