Hi,
classes12.jar and ojdcb14.jar are fairly outdated and no longer supported by Oracle.
Most recent versions are ojdbc5.jar for Oracle 11g, ojdbc6.jar for Oracle 11g and Oracle 12c R1, ojdbc7.jar for Oracle 12c R1 and ojdbc8.jar for Oracle 12c R2 and newer.
The number in the Jar-File names indicates the minimum version of Java these Jars are compatiblie with.
Instead of placing the jars in “\instances\default\lib\jars” they should be placed under “\instances\default\lib\jars\custom” to indicate that these are not default jars but have been added later by customer.
Placing the jars under \instances\default\lib\jars or \instances\default\lib\jars\custom requires a restart of whole IntegrationServer, while placing them under \instances\default\packages\WmJDBCAdapter\code\jars only require a reload of the package WmJDBCAdapter to activate them.
Regards,
Holger
