		- Configures Log4J for this web app.
		- As this context specifies a context-param "log4jConfigLocation", its file path
		- is used to load the Log4J configuration, including periodic refresh checks.
		-
		- Would fall back to default Log4J initialization (non-refreshing) if no special
		- context-params are given.
		-
		- Exports a "web app root key", i.e. a system property that specifies the root
		- directory of this web app, for usage in log file paths.
		- This web app specifies "petportal.root" (see log4j.properties file).

	<!--
		- Loads the root application context of this web app at startup,
		- by default from "/WEB-INF/applicationContext.xml".
		- Note that you need to fall back to Spring's ContextLoaderServlet for
		- J2EE servers that do not follow the Servlet 2.4 initialization order.
		-
		- Use WebApplicationContextUtils.getWebApplicationContext(servletContext)
		- to access it anywhere in the web application, outside of the framework.
		-
		- The root context is the parent of all servlet-specific contexts.
		- This means that its beans are automatically available in these child contexts,
		- both for getBean(name) calls and (external) bean references.
