what is the diffrence between addErrors&saveErrors?

mohanrao

use saveErrors() in validate() method of ActionForm class and use addErrors() in else where

M Kalyan Tilak

Follwing example of the ActionForm and action class will give u clear idea abt diff.


1.Validate method in the form
 public ActionErrors validate(ActionMapping mapping, HttpServletRequest req) {
        ActionErrors errors = super.validate(mapping, req);

        if (guaranteeRequired == 1) {
            //No Guest Guarantee
            if ("".equals(planName)) {
                errors.add(ActionErrors.GLOBAL_ERROR,
                    new ActionError("PPlDC_ValErrMsg_6"));
            }

            if ("".equals(otherPayNotes)) {
                errors.add(ActionErrors.GLOBAL_ERROR,
                    new ActionError("PPlDC_ValErrMsg_1"));
            }

            if (!("".equals(receiveDate))) {
                Date date = DateValidator.isValid(receiveDate,new Locale("EN_US"));

                if (date == null) {
                    errors.add(ActionErrors.GLOBAL_ERROR,
                        new ActionError("PPlDC_ValErrMsg_5"));
                    receiveDate = "";
                }
            }

            //Flag for checking "no guest guar required" in gpaytypevo
            if ((amount != null) && !("".equals(amount))) {
                double amountDouble = 0;

                try {
                    amountDouble = Double.parseDouble(amount.trim());
                } catch (NumberFormatException numEx) {
                    //Amount should be a numeric value
                    errors.add(ActionErrors.GLOBAL_ERROR,
                        new ActionError("PX_ERR_GP_AMOUNT"));
                }

                if ((amount.trim().length() > 10) || (amountDouble > 999999.99)) {
                    //Amount should be less that 10 characters and should not be greater than 999999.99
                    errors.add(ActionErrors.GLOBAL_ERROR,
                        new ActionError("PX_ERR_GP_AMOUNTRANGE"));
                }
            }

            if ((referenceItem != null) && !("".equals(referenceItem))) {
                int refItem = 0;
                if (referenceItem.trim().length() > 40) {
                    //Reference Item should not be greater than 40 characters long
                    errors.add(ActionErrors.GLOBAL_ERROR,
                        new ActionError("PX_ERR_GP_REFITEM"));
                }
                try {
                    refItem = Integer.parseInt(referenceItem);
                } catch (NumberFormatException numEx) {
                    //Reference Item should be a numeric value
                    errors.add(ActionErrors.GLOBAL_ERROR,
                        new ActionError("PX_ERR_GP_REFITEMNUME"));
                }

                if (refItem < 0) {
                    //Reference Item should be greater than zero
                    errors.add(ActionErrors.GLOBAL_ERROR,
                        new ActionError("PX_ERR_GP_REFITEMRANGE"));
                }
            }

            if ((checkNumber != null) && !("".equals(checkNumber))) {
                int checkNumInt = 0;
                if (checkNumber.trim().length() > 40) {
                    //Check Number should not be greater than 40 characters long
                    errors.add(ActionErrors.GLOBAL_ERROR,
                        new ActionError("PX_ERR_GP_CHECKNUM"));
                }

                try{
                    checkNumInt = Integer.parseInt(checkNumber);
                } catch (NumberFormatException numEx) {
                    //Check Number should be a numeric value
                    errors.add(ActionErrors.GLOBAL_ERROR,
                        new ActionError("PX_ERR_GP_CHECKNUMNUME"));
                }


                if (checkNumInt < 0) {
                    //Check Number should be greater than zero
                    errors.add(ActionErrors.GLOBAL_ERROR,
                        new ActionError("PX_ERR_GP_CHECKNUMRANGE"));
                }
            }
        } else {
            if (paymentByCC || paymentByNonCC) {
                if ("".equals(guaranteePlanName)) {
                    errors.add(ActionErrors.GLOBAL_ERROR,
                        new ActionError("PPlDC_ValErrMsg_6"));
                }
            }

            if (paymentByNonCC) {

                    if (!("".equals(dueDate))) {
                    Date date = DateValidator.isValid(dueDate,new Locale("EN_US"));

                    if (date == null) {
                        errors.add(ActionErrors.GLOBAL_ERROR,
                            new ActionError("PPlDC_ValErrMsg_3"));
                        dueDate = "";
                    } else {
                        dueDate = new SimpleDateFormat("MM/dd/yyyy").format(date);
                    }
                }

                if (!(numDaysDue.equals("")) || !(numDaysDue.length() == 0)) {
                    Pattern p = Pattern.compile("[0-9]+");

                    //Match the given string with the pattern
                    Matcher m = p.matcher(numDaysDue.trim());

                    //check whether match is found
                    boolean matchFound = m.matches();

                    if (!matchFound) {
                        errors.add(ActionErrors.GLOBAL_ERROR,
                            new ActionError("PPlDC_ValErrMsg_4"));
                        }
                    }
                }
            }

        if (errors.size() > 0) {
            validationErrors = true;
        } else {
            validationErrors = false;
        }

        return errors;
    }

2. Action class method using save error in the exception class.

    public ActionForward remove(ActionMapping mapping, ActionForm form,
        HttpServletRequest request, HttpServletResponse response)
        throws Exception {
        logger.entering();

        List paymentPlanList = null;
        ActionErrors errors = new ActionErrors();

        GuaranteePaymentForm paymentForm = (GuaranteePaymentForm) form;

        try {
            ResdeskSessionManager session = ResdeskPageAction.getResdeskSessionManager(request );
            PKComponentRequestVO requestVO = session.getPKComponentRequestVO();
            PKResdeskXDelegate pkResdeskXDelegate = new PKResdeskXDelegate();

            if (ResdeskPageAction.checkAndTouchLogin(request, response,
                        PasskeyUtils.getResDeskAppID().intValue())) {
                return null; // session has expired
            }

            requestVO.setComponentTypeId(PKComponentRequestVO. GUARANTEE);

            String paymentPlanIdStr = request.getParameter("paymentPlanId");

            if (paymentPlanIdStr != null) {
                int paymentPlanId = new Integer(paymentPlanIdStr).intValue();
                requestVO.setComponentId(paymentPlanId);
                pkResdeskXDelegate.remove(requestVO, new GuaranteePlanCVO());
            }

            paymentPlanList = pkResdeskXDelegate.listByEvent(requestVO);
            session.putSessionData(ConstantDeclareI.GUARANTEEP LANLIST,
                paymentPlanList);

            AccessPrivilegeVO accessPriviligeVO = pkResdeskXDelegate.getAccessPrivileges(requestVO);
            request.setAttribute(ConstantDeclareI.PAYMENTPLAN_ ACCESSPREVILEGE,
                accessPriviligeVO);

        } catch (Exception exp) {
            paymentForm.setValidationErrors(true);
            errors.add(ActionErrors.GLOBAL_ERROR,
                new ActionError(exp.getMessage()));
            saveErrors(request, errors);
        }

        logger.exiting();

        return mapping.findForward("planlist");
    }
