Trying to add a new gateway - error

I have a created a new payment gateway for a company called SafePay but I am getting a runtime error so there must be something I missed. Just not sure what.

Here is the error: PaymentManager.cs line 86 (version 1.5)

var iPaymentMethod = Activator.CreateInstance(Type.GetType(paymentMethod.ClassName)) as IPaymentMethod;

value cannot be null

Any ideas?

Please ensure that Class name of your payment module (payment module details page in admin area) really exists. And ensure that you referenced your assembly in NopCommerceStore project (presume, you didn't)

Andrei,

Thanks for the quick response.


-Please ensure that Class name of your payment module (payment module details page in admin area) really exists.
--(yep it does)

- And ensure that you referenced your assembly in NopCommerceStore project (presume, you didn't)
--no, I did.

These are the steps that I have taken.

1.Create class library called Nop.Payment.SafePay
2.Added class SafePayPaymentProcessor.cs as a public class and implement the IPaymentmethod.
3. Add NopBusinessLogic and Nop.Common references to this project
4. compile this class library
5. reference this class in the nopcommerce store
6.Go to Administration in store and add SafePay directory to Payment
7. Add ConfigurePaymentMethod control to this
8. ConfigurePaymentMethod implements BaseNopAdministrationUserControl and IConfigurePaymentMethodModule
9. Go to Templates/Payment
10. Add SafePay directory with PaymentModule control
11. Payment module implements BaseNopUserControl, IPaymentMethodModule
12. Go to Admin and select SafePay under configure. Add the corresponding references and make Active. Save.

That's it but there must be something else I'm missing as it still gives me same error?

Fixed it. It was a typo. Left out the class name when configuring in the administrator. Done, it works.

Hi,
This is your processor class ? and whats your error  ? did u try step by step on the code ...

Thank you for you answer. Yes this is my processor class, is NO ERROR message generated, but after PAYMENT CONFIRMATION page when I click <Next> is not oppening the the page of the Mobilpay card handler page but is skiping back to the PAYMENT INFORMATION page, and the application cycling between these 2 pages and I can not arrive to the page of card processor company.

Hi,
My implementation is almost identical to yours and it works. Check the GetMobilPayUrl() method. Also, you should use a modified version of the RemotePost class where the parameters "data" and "env_key" are not HtmlEncoded.

Bafta

thank you :) ! I also found the problem in this time. Multumesc mult ;)
