If you are connecting to an Access database you are probably using the JDBC-ODBC bridge (type 1 driver) so all those settings are ignored. Or rather, they are not supported by that driver.
There is a problem where inserts and updates don't go through until the next operation is performed on the connection.
Try one of these:
* if you need to, insert another row.
* or you can perform a dummy select like
select id from table * I usually set autoCommit(true) and have no problems. I don't usually recommend doing this, but if it's Access, who cares!
