I found wrong connection string in Oracle documentation on link:
https://www.oracle.com/a/ocom/docs/database/adw-conn-tibco-jaspersoft.pdf Its wrong it should be :
jdbc:oracle:thin:@testy_medium?TNS_ADMIN=C:\\Work_files\\Wo rk_data\\wallets\\TESTY
instead of :
jdbc.oracle.thin@:testy_medium?TNS_ADMIN=C:\\Work_files\\Wo rk_data\wallets\TESTY
For everyone who just copied and modified the path that is the reason of getting connection error.
Hope that they will edit the documentation.
