How to load applicationContext.xml

I trying to load an applicationContext.xml from java class in a web application using 

  ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");

and

ApplicationContext context = new FileSystemXmlApplicationContext("applicationContext.xml");

My question is how to load applicationContext.xml from a java class. The applicationContext.xml is WEB-INF. Is that possible?

A ContextLoaderListener is used when you want to load a specific context that will act as your context root. If you want to load additional contexts for whatever reason, you can define your own ServletContextListener, create your ApplicationContext instances, and put them in the ServletContext attributes so that they are available to the web application 

public class AdditionalContextListener implements ServletContextListener {

    @Override
    public void contextDestroyed(ServletContextEvent sce) {
        // destroy those contexts maybe
    }

    @Override
    public void contextInitialized(ServletContextEvent sce) {
        ApplicationContext context = ...; // get your context
        sce.getServletContext().setAttribute("someContextIdentifier", context);
    }

}

You can use the ContextLoaderListener in your web.xml file: 

<context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param> 

<listener>
  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

Then you can use the WebApplicationContext to load the context: 

WebApplicationContext context = WebApplicationContextUtils.getRequiredWebApplicationContext(servlet.getServletContext());

Hope this helps.
