Is there a way to run a method/class only on Tomcat/Wildfly/Glassfish startup?

Question

I need to remove temp files on Tomcat startup, the pass to a folder which contains temp files is in applicationContext.xml.

Is there a way to run a method/class only

Answer 1

I'm sure there must be a better way to do it as part of the container's lifecycle (edit: Hank has the answer - I was wondering why he was suggesting a SessonListener before I answered), but you could create a Servlet which has no other purpose than to perform one-time actions when the server is started:

  Does stuff on container startup
  StartupServlet
  StartupServlet
  com.foo.bar.servlets.StartupServlet
