In GeoServer (2.13.1) I'm trying to connect to Oracle DB 11g and 12c and connecting successfully both. But in 12c I couldn't see my tables and can't add layer.
There isn't any error message or somethng like it.
Is there any way to reach them or how can i solve it.
-- Solved--
Oracle DB 12c has ojdbc8 driver in library file path but GeoServer is tested and working correctly with ojdbc7. With ojdbc8 successfully connected and listed 11g tables but for 12c just connected to database, didnt list tables who in databese. Changing ojdbc8 to ojdbc7 connected and listed tables from 11g and 12c.
