Execute servlet on startup of the application

Question

I build a web application with JSPs and in my servlet I have:

public class MyServlet extends HttpServlet {
    protected void processRequest(HttpServletReque         


        

Answer 1

In my point of view, a good way is to implement a Servlet Context Listener. It listens to application startup and shutdown.

public class YourListener implements javax.servlet.ServletContextListener {

    public void contextInitialized(ServletContextEvent sce) {
    }

    public void contextDestroyed(ServletContextEvent sce) {
    }
}

And then, you configure the listener in your web.xml () or with the @WebServletContextListener annotation.
