Backing bean code:
*******************
public String someAction() {

ExternalContext context = FacesContext.getCurrentInstance().getExternalContext();

HttpServletRequest request = (HttpServletRequest) context.getRequest();

String parameterValue = request.getParameter("AccountName");

// Code here

return null

}
