public class Login extends MVCPortlet {

    public void loginUser(ActionRequest actionRequest,
            ActionResponse actionResponse) throws IOException, PortletException{
           
            System.out.println("login action called");
           
            String email = ParamUtil.getString(actionRequest, "emailId").trim();
            String password = ParamUtil.getString(actionRequest, "password").trim();
           
            ThemeDisplay themeDisplay = (ThemeDisplay) actionRequest.getAttribute(WebKeys.THEME_DISPLAY);    
            HttpServletRequest request = PortalUtil.getHttpServletRequest(actionRequest);
            HttpServletResponse response = PortalUtil.getHttpServletResponse(actionResponse);
           
            User userDetail = null;
            try {
                userDetail = UserLocalServiceUtil.fetchUserByEmailAddress(themeDisplay.getCompanyId(), email);
                if(Validator.isNull(userDetail)){
                actionRequest.setAttribute("EMAIL_NOT_EXIST", "Account not exist with email");
                  }else{
                boolean passwordMatched = PasswordTrackerLocalServiceUtil.isSameAsCurrentPassword(userDetail.getUserId(), password);
                if(!passwordMatched){
                actionRequest.setAttribute("PASSWORD_NOT_MATCHED", "Please Enter Correct Password");
                }else{
                // if user exist with provide email and given password matched with user database password
                ClassLoader pcl = PortalClassLoaderUtil.getClassLoader();
                        Class lClass = pcl.loadClass("com.liferay.portlet.login.util.LoginUtil");
                        java.lang.reflect.Method method = lClass.getDeclaredMethod("login", HttpServletRequest.class, HttpServletResponse.class, String.class, String.class, Boolean.TYPE, String.class);
                        method.invoke(null, request, response, email, password, false, CompanyConstants.AUTH_TYPE_EA);
                       
                       //redirection after login...
                       String screenName = userDetail.getScreenName();
                       String portalURL = PortalUtil.getPortalURL(actionRequest);
                       if(PortalUtil.isOmniadmin(userDetail.getUserId()))
                       {
                           System.out.println("admin logged in, redirecting to admin  specified private page");
                           actionResponse.sendRedirect(portalURL + "/user/"+ screenName+"/adminuser");
                       } else {
                           System.out.println("normal user logged in, redirecting to private page specified for normal user");
                           actionResponse.sendRedirect(portalURL + "/user/" + screenName +"/normaluser");      
                       }
                }
                 }
              }catch (Exception e) {
                    e.printStackTrace();
