In order to be able to use the CentraSite Application Framework features, the Java classpath must include all the relevant class files. The easiest way to do this is to include all the JAR files that are contained in the folder redist (including the subfolder redist/csaf). The redist folder is typically located at C:\SoftwareAG\CentraSite\redist (Microsoft Windows) or /opt/softwareag/CentraSite/redist (UNIX).
