Windows Phone Server Side Receipt Validation

Question

Hello, we have implemented the code to validate the windows phone IAP receipt on server, however when deploying code we get the following error:

Package can not be used in custom code deployment org.w3c.dom.Node : in source com.shephertz.app42.paas.customcode.sample.SecurityWindowsPhone

Here's the code: http://codepad.org/aBIMTr0D

I understand that I can't use some libraries in Custom Code, but can you please help us choose other libraries that would work for that task?

Answer 1

Hello Vlad,

You can use JSON parser (org.json package) if your response is available as JSON instead of XML. Custom code currently does not have these packages in white list libraries.  However if it is a blocker for you, just write to us at support@shephertz.com to white list request for these libraries.

Let me know if it makes sense.

Thank you. I have contacted the support and asked to grant support for these libraries.

Hello Vlad,

We have given the access to accept those libraries in custom code. You just need to update the below line of code:

From:

Document doc = dbf.newDocumentBuilder().parse(new FileInputStream(signedData));

To:

Document doc = dbf.newDocumentBuilder().parse(signedData);

Kindly make the above changes and deploy your custom code.

Let us know if it helps.
