Hi,
when it comes to webMethods 10.11, using ojdbc10.jar is recommended.
You can open the ojdbc10.jar with any zip tool and you will find a META-INF/MANIFEST.MF in it, beside some other directories which contain the classes for the driver and the data source connector.
From where did you obtain these ojdbc-jars ?
I would recommend to download them the Oracle website (JDBC and UCP Downloads page).
Requires a free registration.
Latest version available is Driver 21c (21.6.0.0.1) coming as either ojdbc8.jar or ojdbc11.jar.
Both variants can be used with wM 10.11, but in this case I would prefer using the ojdbc11.jar.
The Oracle site currently lists driver versions from Oracle 18c up to 21c, consisting of ojdbc8.jar (for all versions listed), ojdbc10.jar (Oracle 19c) or ojdbc11.jar (Oracle 21c).
Additionally make sure that there is only one ojdbc.jar under the instance-directory tree of your IS, ideally under the packages/WmJDBCAdapter/code/jars directory as mentioned above.
I checked the error code you have mentioned above (ORA-28040: No matching authentication protocol) on Google and it is indicating that there is a jar with Oracle version 10 or older being used.
ojdbc14.jar, ojdbc5.jar, ojdbc6.jar and ojdbc7.jar are considered EOL as long as there is no need to use such old jars.
ojdbc8.jar for Oracle Versions below 12c should be also considered outdated as they do not implement latest JDBC 4.x specs.

Holger
