Spring MVC Loads Different web.xml Accordingly

I was having some problem trying to load different web.xml for my Spring MVC project. I have 2 web.xml, one for development and the other for production. Each of the web.xml will load up different filters respectively.

I have this class, upon initialization, the project will execute this class to set the properties:

public class StartupServlet extends HttpServlet {        private final String SYSTEM_URL = "SystemURL";      private Logger log = LogManager.getLogger(StartupServlet.class);        public void destroy() {      }        public void init() throws ServletException {          try {                Logger log = LogManager.getLogger(StartupServlet.class);                ServletConfig config = getServletConfig();              String url = (String) config.getInitParameter(SYSTEM_URL);              Constants.FULLPATHWITHCONTEXT = url;                if (!Constants.CUR_ENV.equals(Constants.CUR_ENV_PROD)) {                  XmlWebApplicationContext context = new XmlWebApplicationContext();                  context.setConfigLocation("/WEB-INF/web_prod.xml");              } else {                  XmlWebApplicationContext context = new XmlWebApplicationContext();                  context.setConfigLocation("/WEB-INF/web.xml");              }                Constants.SERVLET_CONTEXT = this.getServletContext();          } catch (Exception e) {          }      }  }  

I am trying to set it to load different web.xml according to the value I set for CUR_ENV in Constants.java. However, it just keep loaded up the web.xml regardless if I set the CUR_ENV to CUR_ENV_PROD.

Any ideas on how to do this? Thanks!
