Users - DataCash - Andrew Sykes

[Charles Johnson-2]

Andrew,

I'm back from my break and have got the DataCash end of things working
and am now looking at what i have to do to integrate it.

I thought it could be an idea to get myself a CyberSource test account
and see that in action first. Only problem is i can't get my keys
generated yet as i can't log in to their site's keygen page ;-)

I'm not sure how the (apparently) generic PaymentGatewayServices works
in conjunction with particular services, such as IcsPaymentServices. I
would imagine that the former hands off to the latter, but i'm not sure
where and how.

Also, i wonder if you have any experience of processing with CyberSource?

CJ

Charles,

No, I haven't used CyberSource before unfortunately.

As for setting up a test account, perhaps it would be easier to set one
up with Paypal, that might get the ball rolling at least...

As a little indication of how the payment stuff hangs together, let's
take a quick look at a refund...

To refund a payment, OFBiz calls the refundPayment service of
PaymentGatewayServices.java like so...

Map serviceResult = dispatcher.runSync("refundPayment", UtilMisc.toMap
("orderPaymentPreference", orderPayPref, "refundAmount",
thisRefundAmount, "userLogin", userLogin));

I guess this service is analogous to a factory object in that it works
out the specific implementation to use, although I doubt that analogy
could get you too far!

In PaymentGatewayServices.refundPayment() you'll see lines like this...
...
...
GenericValue paymentSettings = null;
if (orderHeader != null) {
paymentSettings = getPaymentSettings(orderHeader, paymentPref,
REFUND_SERVICE_TYPE, false);
}
...
...
String serviceName = paymentSettings.getString("paymentService");
...
...

Here, you are getting the implementation specific service name for
refunding.

Once PaymentGatewayServices has that, it does the refund like so...
...
refundResponse = dispatcher.runSync(serviceName, serviceContext,
TX_TIME, true);
...

In the case of CyberSource, serviceName would contain the name of the
CyberSource refund service "cyberSourceCCRefund".

Just for clarity, you won't find a method in IcsPaymentServices called
"cyberSourceCCRefund". This is because the service name is mapped to
IcsPaymentServices.ccRefund() in the xml file "services_cybersource.xml"
like so...

<service name="cyberSourceCCRefund" engine="java"
location="org.ofbiz.accounting.thirdparty.cybersource.IcsPaymentServices" invoke="ccRefund">
        <description>Credit Card Processing</description>
        <implements service="paymentRefundInterface"/>
</service>

Obviously, there's a lot going on in there, but hopefully that gives you
some indication of how it's hanging together.

Kind Regards

I've got an acount with PayPal but the problem there is two-fold:

a. i don't know of a way of sending test data
and more importantly,
b. PayPal doesn't (AFAICR) notify synchronously and therefore would be a
bad analog for DataCash

In fact, this second reason, since the asynchronous notifications are
probably not durable, makes it a bad candidate for solid processing IMO

Still inspecting your info regarding flow. Thanks for that

Charles,

You're probably right about Paypal, I was having my doubts even as I
typed it...

Let me know how you get on...

Kind Regards

OK thanks. It would be useful to go into some sort of trace debug mode
so i can follow the application flow. Is that possible?

Charles,

In base/config/debug.properties

You will see a line like this...
print.verbose=ftrue

Changing this to true will dramatically increase the amount of trace you
see.

Kind Regards

Hmm yes, but i really meant an IDE debug, such as Eclipse. I may be able
to do without it though. It's probably slight frustration at big
picture/small picture stuff as i normally studiously avoid debuggers ;-)
