How to activate Spring Container in Web Application?

One of the ways to Activate Spring 'ApplicationContext' container is

First Configure the Spring configuration file in web.xml file

eg:

<context-param>

  <param-name>contextConfigLocation</param-name>

  <param-value>WEB-INF/Spring.cfg.xml</param-value>

</context-param>

and next Configure the ContextLoaderListener

<listener>

      <listener-class>

org.springframework.web.context.ContextLoaderListener

      </listener-class>

</listener>

and finally in Servlet

ApplicationContext context=WebApplicationContextUtils.

    getRequiredWebApplicationContext(config.getServletContext());

It is done. Now ApplicationContext Container will be activated.
