Side-by-side installation of the viewers SDK

You can have two different versions of the viewers SDK installed on a single machine (referred to as a side-by-side installation). The recommended method of achieving a side-by-side installation is to use the WEB-INF\lib directory of your web server to house the JAR files required by the viewers SDK. See JAR files needed for deployment of SAP BusinessObjects software for details. When a new version of the viewers SDK is installed, the new JAR files that are automatically installed do not overwrite the JAR files in your WEB-INF\lib directory. By maintaining the older version of the SDK, your web application can continue to use the older library until you are ready to migrate to the newer version.
To migrate to the new version, make the appropriate changes to your web application, and then copy the new JAR files into the WEB-INF\lib directory.
