RE: MVC initialization

[Robert Taylor <rt...@mulework.com>]

A standardized approach would be to implement a ServletContextListener and define it
in your web.xml for the web app. It will be invoked before the web app accepts any requests
and when the web app is shutdown.

A more "Struts" approach would be to use a PlugIn and define it in your struts-config.xml file.

Both of these methods provide you with bootstrapping your web app.

Note that the only compelling reason to use a PlugIn would be if you 
were still only on Servlet 2.2 (when it hadn't yet been introduced) 
or if you needed your PlugIn to have a reference to the ModuleConfig 
object corresponding to the Module in which the PlugIn was defined.

Just wanted to point out that just because it's a "more 'Struts'" 
approach, it's not necessarily better.

Then again, I keep writing PlugIns myself, just out of habit.  They work.
