Bootstrap listener to start up Spring's root WebApplicationContext. Simply delegates to ContextLoader.

This listener should be registered after Log4jConfigListener in web.xml, if the latter is used.

For Servlet 2.2 containers and Servlet 2.3 ones that do not initalize listeners before servlets, use ContextLoaderServlet. See the latter's Javadoc for details.
