How to write startup code 1

[phatening]

Hi fellow programmers,

Does anyone know how to write startup code(code that is ran only when the web app is started or restarted) for a web application thats being written with JSP and Java servlets?

I'm trying to write code that accesses the database once everytime the web application is started/restarted to delete expired records.

I appreciate any help. Thanks.

The HttpServlet has an init() method which is called by the servlet container when the servlet is placed into service (this is inherited from GenericServlet). You can override this method in your servlet class to achieve your aims.

Note that there is a matching destroy() method which is called by the servlet container when the servlet is taken out of service.
