It seems the code is wrong.
If you want to use autocommit mode, then it should be set before the query is executed (typically, after the getConnection()) - not once the query has been executed.
If you don't want to use autocommit, then you need an explicit con.commit() after the statement has been executed. You may want to have a look at the documentation for more information.
Since you have fixed your exceptions due to missing jdbc driver, it should work now.
