Could not find the main class: oracle.apps.ad.rapidwiz.RIWizard. Program will exit.

Cause: 

Rapidwiz is expecting a 32-bit version of the JDK, and the error occurs because the only version available is 64-bit.

The issue is discussed in the following unpublished defect:

Bug 24386615 – STARTCD SHOULD BE UPDATED TO USE 64 BIT VERSION OF THE JDK/JRE .

Solution:

Copy a 64 bit version of the JDK from any 12c Oracle Home.

To resolve the issue test the following steps in a development instance and then migrate accordingly:

1. Backup the existing JDK located in startCD/Disk1/rapidwiz/jre/Linux_x64/

2. Copy a 64 bit version of the JDK to a zip file from any 12c Oracle Database or Grid Home located in $ORACLE_HOME/ via the following command:
$ zip -ryT 1.6.0.zip jdk

3. Move the zip file 1.6.0.zip (via scp or other) into startCD/Disk1/rapidwiz/jre/Linux_x64

4. Unzip file 1.6.0.zip in directory startCD/Disk1/rapidwiz/jre/Linux_x64

5. Retest Rapidwiz and confirm the error is resolved.
