Thanks for hint, but could you be more specific?! What is wrong with my approach, that I cannot get rollback?

public void storeOwnerPlain(Owner owner) throws SQLException {
String[] sql = new String[2];
Connection con = null;
try {
// con = getDataSource().getConnection();
con = DataSourceUtils.getConnection(getDataSource());
TransactionStatus status = TransactionInterceptor.currentTransactionStatus();
sql[0] = "insert into owners " +
"(first_name, last_name, address, city, telephone)" +
"values ('Ang', 'Lee', '1st Street', 'Boston', '10000')";
sql[1] = "insert into owners " +
"(first_name, last_name, address, city, telephone)" +
"values ('Ang', 'lee', 'Taiwan')";
Statement stat = con.createStatement();
for (int i = 0; i < 2; i++) {
stat.executeUpdate(sql[i]);
}
} catch (SQLException e) {
logger.info(".. sql.exception: " + e);
throw e;
}
}
