Hi,
Do you see this error on MWS console? Can you provide the MWS logs for further investigation.

I see the problem here is with JDBC drivers not being able to load.

Hi BJCO,
Please elaborate more on this issue. What you were trying to achieve when you got this error.
Moreover at first instance it seems either oracle database connection JAR is missing or it is not in classpath or databaseDriver/Class mentioned in the adapter setting is incorrect.
