The StartupManager is introduced in VIVO release 1.4

Description

Like most Java Enterprise applications, Vitro servlets rely on the ServletContext to hold object that they will need to use when servicing requests. These objects are created by ServletContextListeners, which are run by the StartupManager.

...

When logged in, an administrator may view the StartupStatus from a link on the Site Admin page.

Specifying context listeners

In any Java Enterprise application, developers can specify context listeners in the deployment descriptor (web.xml). These listeners that will be activated when the application starts and when it shuts down.

...

Vitro contains a list of startup listeners in a file at Vitro/webapp/config/startup_listeners.txt. This file is simple text with each line containing the fully-qualified class name of a startup listener. Blank lines are ignored, as are comment lines – lines that begin with a “hash” character. Here is a portion of that file:

 #
 # ServletContextListeners for Vitro, 
 # to be instantiated and run by the StartupManager.

 edu.cornell.mannlib.vitro.webapp.config.ConfigurationPropertiesSetup
 
 edu.cornell.mannlib.vitro.webapp.config.RevisionInfoSetup
 
 edu.cornell.mannlib.vitro.webapp.email.FreemarkerEmailFactory$Setup
 
 # DefaultThemeSetup needs to run before the JenaDataSourceSetup to allow creation
 # of default portal and tab
 edu.cornell.mannlib.vitro.webapp.servlet.setup.DefaultThemeSetup

Writing context listeners

Each listener must implement the ServletContextListener interface, and must have a zero-argument constructor.
