When connecting to 10g ,11g or 12c databases using a JDBC thin driver , fails with following errors:
The Network Adapter could not establish the connection
ORA-28040: No matching authentication protocol
This happens because you are using a non compatible version of JDBC driver.
To resolve this issue, make sure that you are using the latest version of Oracle JDBC driver, if not use JDBC 12c or higher versions.
