How would I go about having a certain piece of code executed as soon as my Vaadin application is started? I have found the servletInitialized() method, but this requires the page to be requested before the code is executed. Is what I need possible?
Hello,
You can do that with a ServletContextListener :

(or with the annotation @WebListener )
Or with a simple servlet with auto-load set to true
