Creating an ApplicationContext from a Web Application As opposed to the BeanFactory, which will often be created programmatically, ApplicationContexts can be created declaratively using for example a ContextLoader. Of course you can also create ApplicationContexts programmatically using one of the ApplicationContext implementations. First, let's examine the ContextLoader and its implementations. The ContextLoader has two implementations:.. The ContextLoaderListener and the ContextLoaderServlet They both have the same functionality but differ in that the listener can not be used in Servlet 2.2 compatible containers Since the Servlet 2.4 specification, listeners are required to initialize after startup of a web application . A lot of 2.3 compatible containers already implement this feature It is up to you as to which one you use, but all things being equal you should probably prefer ContextLoaderListener;. for more information on compatibility, have a look at the JavaDoc for the ContextLoaderServlet .You can register an ApplicationContext Using The ContextLoaderListener As Follows:
