Vibe 4.0.1 requires that you also install the Java Cryptography Extension (JCE) in addition to the JDK on each server in your Vibe system. (This was not a requirement in Vibe 4 and earlier.)
Before you begin the upgrade process, install the JCE on each server in your Vibe system, as described in Section A.2, Java Cryptography Extension (JCE).
