Hello everybody, I tried to change to use the OJBDC14.jar having used the Oracle12.jar and everything seemed fine until I updated a String. Then it puts nonsense in the first 3 bytes. If I go back to using Oracle12.jar it works fine. I guess I need to change something in the mapping - does anybody have a clue why this might happen. It looks to me like length information or something similar is being passed with the front of the string.
