How can I start/stop my web application from a JSP page?

Go to all tips in JSP, Servlets

Question: How can I do soft startup and graceful shutdown from within a JSP based web application?

I have multiple threads that running in my application and I need start/stop them without exceptions. I can not run my threads in a JSP page.

Answer: There are two methods which you can always use to initialize and shutdown your web JSP application from a JSP page:


Code:


public void jspInit() {
    ... 
}

public void jspDestroy() {
    ... 
}


Inside of those methods you can place all necessary code or call to another classes, where you need to do something before your application will be stopped. It is good idea to put those methods into first, front page of your application. Having them there you avoid a risk that the methods never run and you never spend much time trying to tune/debug your JSP applications with tons of Java tools and utilities.
