Hello everyone,

I am trying to implement spring security check  for authentication in login page.

public String doLogin() throws IOException, ServletException {

        if(username == null ||username.equals("") ||

            password==null || password.equals("") ){

            CommonUtils.showMessage(FacesMessage.SEVERITY_INFO, "Required :", "Both fields are required");

        }else{

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

        RequestDispatcher dispatcher = ((ServletRequest) context.getRequest()).getRequestDispatcher("/j_spring_security_check");

        dispatcher.forward((ServletRequest) context.getRequest(),(ServletResponse) context.getResponse());

         FacesContext.getCurrentInstance().responseComplete();

        }

          return null;

    }

Page is not getting redirected to index.jsf.It is showing error page.No active contexts....

  public void init() {

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

        HttpServletResponse response = (HttpServletResponse) context.getResponse();

        HttpSession session = (HttpSession) context.getSession(false);

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

        try {

            if (session.getAttribute(HTTPSessionVariables.USERNAME) != null) {

                response.sendRedirect(request.getContextPath() + "/pages/index.jsf");

            }

        } catch (Exception e) {

            log.error("Error in LogoutBean " + e);

        }

    }
