 ServletContext context =getServletContext();
 String pattern = context.getInitParameter(MobilePattern);

After searching i got way to get instance of FacesContext and from which i get refrence to ExternalContext and after obtaining ExternalContext's reference i am able to use its methods but i am unable to obtain.

my web.xml entries are still same

FacesContext context = FacesContext.getCurrentInstance();
String pattern = context.getExternalContext().getInitParameter("MobilePattern");
     

any suggestion please
