Using Google Checkout SDK

The Google Checkout API Java SDK provides a library and instructions to integrate Google Checkout XML APIs in your Web applications. The release notes document the updates in this release.

Using the SDK

The remainder of the instructions assume that you unzipped the checkout sdk at checkout-sdk/ directory. Here are the steps to use this SDK:

Copy checkout-sdk.jar to your WEB-INF/lib
Copy checkout-sdk/web/WEB-INF/checkout-config.xml to your WEB-INF/ directory
Edit your WEB-INF/web.xml and cut-and-paste the contents from web/WEB-INF/web.xml
1. If you need to add additional handlers to process checkout notifications, edit checkout-config.xml and change default value of the handlers to your classes.
2. Use Checkout SDK Javadocs to extend notification handlers
3. The Checkout SDK Source code is available under the project/ directory if you need to learn how the notification handlers work
Copy over the contents of web/checkout to a suitable directory in your application. For example, web/checkout
Your application is now ready to use Google Checkout APIs. Deploy it on tomcat or another application server to test the integration.

Building the Source-code

The source-code for Checkout SDK is included in the project/ directory.

To run it from NetBeans, just load up the project/ directory as a NetBeans project. Configure tomcat, and deploy the application to run it.
To build the application from command-line, cd to the project/ directory and follow these steps:
1. Edit build.properties and adjust the value of tomcat.home to point to your Tomcat installation. If you intend to use a different application server, you can ignore the tomcat.home variable, and instead adjust the servlet-api-jar.path property directly to point to the location of servlet-api.jar
2. Make sure that you have ant installed, and run ant -f standalone-build.xml
3. Check dist/ directory to see newly created checkout-sdk.jar and checkout-war.jar
