How to get inserted record if connection is auto commit false in JDBC and MySQL

I am trying to insert record in child table in MySQL using JDBC. But not able to get inserted id of parent table. Below is my code:

con = DAOManager.getConnection();
con.setAutoCommit(false);

voucherArgs.add(voucher.getVendorId());
voucherArgs.add(voucher.getDate());
voucherArgs.add(voucher.getDiscount());
voucherArgs.add(voucher.getDiscountAmount());
voucherArgs.add(voucher.getSubTotal());
voucherArgs.add(voucher.getTotalAmount());
voucherArgs.add(voucher.getInvoice());
voucherArgs.add(voucher.getEmployeeId());

String sqlString = "INSERT INTO recieving_voucher (I_VENDOR,D_VOUCHER,DISCOUNT,DISCOUNT_AMT,SUB_TOTAL,n"
        + "TOTAL_AMT,INVOICE,I_EMPLOYEE) VALUES (?,?,?,?,?,?,?,?)";

//insert voucher entry
SQLExecutor.insertOrUpdate(sqlString, voucherArgs, con);

Integer maxId = (Integer) SQLExecutor.executeQueryWithoutArguments("SELECT MAX(I_RCV_VOUCHER) FROM recieving_voucher ", new GetIntHandler());
