How do I update the Java SDK?

If you modify SDK source code or properties files, you must rebuild the SDK to reflect these changes.

Here's how to rebuild the PayPal SDK:
  1. Install the Ant build software, which the SDK uses to build itself. You can download Ant from http://ant.apache.org/.
  2. After you install the software, set your PATH environment variable to include the Ant bin directory. In SDK_root, use the following commands to perform the corresponding task:
     
    Important: Before running these commands, set your PATH environment variable to the location of the Java distribution’s bin directory, as shown in the following example:
C:\Program Files\Java\j2eesdk-1_4\jdk\bin;Command - Descriptionant - Complete build of SDKant - clean Delete build output filesant doc - Generate Javadoc documentation in SDK_root/docsant update - Rebuild the SDK after WSDL changesant rollback -
  1. Restore the SDK to its previous state if the update fails or has unexpected results.
