Cause: A request was made to generate declarations for all
the types in a database schema. Either the schema was not
found, no user-declared types were found in the schema, or

Action: Ensure that a login/password string was specified
for OTT and that the Oracle database can be accessed with
it. Ensure that the USER_TYPES table contains at least one row.
