This is a simple Java code sample to create a dynamic Amazon Payments 'Subscription' widget

Prerequisites

• You must have an Amazon Payments Sandbox Business Account.

• You must use the same email address and password for your Amazon Payments Business Account and your Amazon Web Services developer account.
• You must have Java version 1.5 or later installed

Using the Sample

1. Sign into your Amazon Web Services developer account and retrieve your Access Key ID and Secret Access Key from here.
2. Replace the value of the accessKey constant in the code sample with your Access Key ID
3. Replace the value of the secretKey constant in the code sample with your Secret Access Key
4. Copy commons-codec-1.3.jar (provided in the thirdparty folder) to a folder (say JARS-FOLDER).
5. Compile & Run the code sample as:
• For Linux Users:
• $javac -cp .:<JARS-FOLDER>/commons-codec-1.3.jar SubscriptionWidgetUtils.java
• $java -cp .:<JARS-FOLDER>/commons-codec-1.3.jar SubscriptionWidgetUtils

• $java -cp .;<JARS-FOLDER>/commons-codec-1.3.jar SubscriptionWidgetUtils
6. The code sample will output the HTML for the 'Subscription' widget to the Console
7. You can now integrate this code into your website
8. Note: You cannot use your Amazon Payments Business Account as a buyer while testing your 'Subscription' Widgets. You should create a new Amazon Payments account which you can use as a buyer.
