Communication between Servlet and separate application?

Hello,

i am pretty new to servlets. what i am trying is to communicate between a servlet and a java application on one physical machine.

i have a servlet that receives data from users and puts it in a database. now i need a separate application that is constantly doing calculations based on the data in the database. i do not want to initiate the calculations via the servlets, but the application should somehow be notified by the servlet if some data has been put into the DB.

is there any way of doing this ?

thanks
