When attempting to reverse engineer a Hyperion Essbase model using Oracle Data Integrator (ODI) 12c, an ODI-1590 script error with a java.lang.NoClassDefFoundError is encountered.

Error as seen in the Standalone agent log:

ODI-1590: The execution of the script failed.
Caused By: org.apache.bsf.BSFException: exception from Jython:

In the case of Standalone agent, the issue happens even after putting the AddJavaLibFile lines into odi.conf file:

AddJavaLibFile ORACLE_HOME\Oracle_Home\odi\sdk\lib\ess_japi.jar
AddJavaLibFile ORACLE_HOME\Oracle_Home\odi\sdk\lib\ess_es_server.jar
