     * / 
    @Override 
    public  void contextInitialized (ServletContextEvent SCE) {
         // get servletContext domain 
        ServletContext servletContext = sce.getServletContext ();
         // Gets the virtual path 
        String contextPath = servletContext.getContextPath ();
         / / path into domain 
        servletContext.setAttribute ( " path " , the contextPath); 
    } 
    @Override
