Struts has plugins which, I think do the kind of thing you are after. Personally I've never used them - I just implement a ServletContextListener to do that sort of thing.
This is exactly right: if you're using Servlet 2.2 (which doesn't have ServletContextListener), you can use PlugIn. If you're using Servlet 2.3 or newer, about the only other thing that PlugIn gets you which an SCL doesn't is that its init() method receives a reference to the Struts ModuleConfig for which the plugin is being initialized -- so if you need a handle on that object, using a PlugIn is probably the most straightforward way to get one.

Hello again everyone... I am starting conversion of a none-Struts app to Struts, and mostly it's straight-forward, but two things I have questions about...
The home-grown framework this app was written with has the
notion of an App
Loader. Basically, this is a class that runs at startup and
reads in some
config information and stores it in a static config object. The properties
of this object are referenced throughout the app.
The other concern is that this same process spawns a couple of low-priority background threads to do some various things throughout the lifetime of the app.
My question, which I have been unable to find an answer to on my own, is if Struts has a similar startup "initialization" mechanism? If not, do I simply create my own servlet to do all this work and set it to run on startup in web.xml? I have no problem with the later approach, but I'm wondering if Struts has a mechanism for this, like our custom framework does?
Thanks all!
