REST - Interoperability (manage sessions on multiple channel) WCtoken and Web Identitytoken

Interoperability of Commerce Tokens between web and rest Channel at same time 

WebSphere commerce FEP8 onwards supports concurrent active session for user on web as well as on Rest channel as same time. However if you are on a lower version of Commerce below are the steps to make your application work seamlessly.

Step 1: If you are on a version lower than WCS 7, FEP 8;  you need to install an APAR JR45670.

Step 2: After installation of APAR you need to extend the Command SimultaneousLogonHelperCmdImpl and override functions as below:

    public boolean isReusingActivityTokenAllowed() {
        final String METHODNAME = "isReusingActivityTokenAllowed";
        LOGGER.logp(Level.INFO, CLASSNAME, METHODNAME, " Setting isReusingActivityTokenAllowed to TRUE ");
        return true;
    }

    public boolean shouldInvalidateLogons() {
        final String METHODNAME = "shouldInvalidateLogons";
        LOGGER.logp(Level.INFO, CLASSNAME, METHODNAME, " Setting shouldInvalidateLogons to FALSE ");
        return false;
    }

Step 3: Generate WCToken using code below:

        String userCookieName = "WC_USERACTIVITY_"+userId.toString();
        LOGGER.logp(Level.INFO, CLASSNAME, methodName,"UserId "+userId + " userCookieName "+userCookieName);
        String currentCookieValue = null;
        try    {
            Cookie [] cookieArray = getHttpRequest().getCookies();
            if(null!=cookieArray && cookieArray.length>0){
                for (int i=0;i                    if(cookieArray[i].getName().equalsIgnoreCase(userCookieName)){
                        currentCookieValue = cookieArray[i].getValue();
                        break;
                    }
                }
            }

            ActivityToken activityToken=null;
            String cookieValue=null;
            WCUserSession userSession = new WCCookieUserSession(currentCookieValue, CommerceTokenHelper.getSessionKey());
            activityToken = userSession.getConversationToken();
            activityToken.setTemporary(false);
            ActivityTokenProcessor.refreshSignature(activityToken);
      
            // generate the WCToken
            String merchantKey = CommerceTokenHelper.getSessionKey();
            WCCookieUserSession cookieUserSession = new WCCookieUserSession(null, null, merchantKey, null, null);
            cookieUserSession.setUserId(userId);
            cookieUserSession.setConversationToken(activityToken);            
            cookieValue = cookieUserSession.serialize();
          
            // retrieve the encrypted part
            String encryptedPart = cookieValue.substring(cookieValue.lastIndexOf(SessionConstants.COOKIE_SEPARATOR) + 1);
            StringBuffer cookieValueBuffer = new StringBuffer(userId.toString().length() + 1 + encryptedPart.length());
            // add the user ID part
            cookieValueBuffer.append(userId);
            cookieValueBuffer.append(SessionConstants.COOKIE_SEPARATOR);
            // add the encrypted part
            cookieValueBuffer.append(encryptedPart);
            wcToken = URLUTF8Encoder.encode(cookieValueBuffer.toString());  //This is the wcToken.

            LOGGER.logp(Level.INFO, CLASSNAME, methodName,"wcToken" +wcToken);

        }catch (Exception e) {
            throw new ECApplicationException(XXXXMessage._ERR_TOKENGENERATION_ERR, CLASSNAME, methodName, new Object[]{e});
        }

WebSphere Commerce - Shipping Modes and Calculations

Troubleshooting Shipping Modes and charges:

It happens that sometimes we set up Shipping modes and charges properly for a Store but we are not able see those values on our shipping billing page or where ever we display Shipping mode types or shipping charges does not get reflected whenever you change the shipping modes.

If you are sure that your set up is correct and still you are not able to see charges, please validate your data in tables with below queries:

SELECT * FROM CALCODE WHERE CODE = 'ShippingCODE';

SELECT * FROM CALRULE WHERE CALCODE_ID = (SELECT CALCODE_ID FROM CALCODE WHERE CODE = 'ShippingCODE');

SELECT * FROM CALSCALE WHERE CODE = 'ShippingScale like FedEx Overnight';

SELECT * FROM CALRANGE WHERE CALSCALE_ID = (SELECT CALsCALe_ID FROM CALSCALE WHERE CODE = 'ShippingScale like FedEx Overnight');

SELECT * FROM CALRLOOKUP WHERE CALRANGE_ID in (SELECT CALRANGE_ID FROM CALRANGE WHERE CALSCALE_ID = 
(SELECT CALSCALE_ID FROM CALSCALE WHERE CODE = 'ShippingScale like FedEx Overnight'));
SELECT * FROM CRULESCALE WHERE CALSCALE_ID = (SELECT CALSCALE_ID FROM CALSCALE WHERE CODE = 'ShippingScale like FedEx Overnight');

SELECT * FROM CRULESCALE WHERE CALrule_ID in (SELECT CALRULE_ID FROM CALRULE WHERE CALCODE_ID = 
(SELECT CALCODE_ID FROM CALCODE WHERE CODE = 'ShippingCODE'));
SELECT * FROM CATENCALCD WHERE CALCODE_ID = (SELECT CALCODE_ID FROM CALCODE WHERE CODE = 'ShippingCODE');

SELECT * FROM SHPJCRULE WHERE CALrule_ID in (SELECT CALrule_ID FROM CALRULE WHERE CALCODE_ID = (SELECT CALCODE_ID FROM CALCODE WHERE CODE = 'ShippingCODE'));
SELECT * FROM FFMCENTER f , STOREENT s WHERE s.MEMBER_ID = f.MEMBER_ID AND s.IDENTIFIER ='StoreIdentifier';
