Problem when I insert data in a MySQL database

[cthibaut]

I have a batch program write in Java. This program insert a lot of data in a MySQL database.
This program seems to work fine but some data has not insertted in the database.
In the log file, I see the call of excecuteUpdate with the correct request, there are no error, but I don't see the data in the Database.

Has anyone know a similar problem ?
