I have a bunch of common application-wide static data objects in my web application. I want to load them at startup so I don't waste time getting them from the data store each time I need them. The only way I know how to do this is with filters. In the filter check to see if the objects are loaded, if not load them as servlet context attributes.

I keep thinking there must be a way to put a class in the application context on startup so that the filter does not have to check on each request.

Any ideas?

Explore the concept of the context listener.

Another (older & inferior) strategy is to define a servlet that loads on startup and initializes system-wide objects.
