tomcat server response after continuous interval?

I want in my j2me application that a server check a table in database and send respo开发者_StackOverflownse to the application after some interval. I am using Tomcat as server. Any suggestion how and what way I will implement it?

Do you want tomcat to take initiative to send a response after specific time interval? Are you using Ajax in application. What you can do is in your application, at client side run a thread which can make a request to tomcat after a specific time interval and get a response.
