On CC&B v2., the Production environment has been cloned to have dev and test instances. As part of the development, the solution is extended to Non-Domestic customers and for these customers the "New" Rating Engine is used.

When running SIT environment in "Embedded" mode, it works fine.
When running in "Native" mode, (run to create EAR files and deploy to the WLS cluster), when running a Rate Check, the following error occurs.
