Hello I am struggeling to establish an automatic connection to my jdbc database. When ever I run the program it gives me this error: java.sql.SQLNonTransientConnectionException:java.net.ConnectException:Error connecting to server localhost on port 1527 with message Connection refused: connect.
When I manually connect to my jdbc driver the program works fine. I would like to know if there is a way that I can connect to the driver using code instead of doing it mannualy.
Here is some of my code:
String createDB = "jdbc:derby://localhost:1527/C:/211092207/HotelBookings;create=true";
String createCustomer = "CREATE TABLE CUSTOMER ( CUSTOMERID NUMERIC(15) NOT NULL PRIMARY KEY, LASTNAME VARCHAR(20), FIRSTNAME VARCHAR(20), GENDER CHAR(1), EMAIL VARCHAR(50), CREDITRATING VARCHAR(9), NATIONALITY VARCHAR(20), DATEOFBIRTH VARCHAR(20), PHONE NUMERIC(10), CELLPHONE NUMERIC(10) )";
String createRoom = "CREATE TABLE ROOM ( ROOMNO NUMERIC(5) PRIMARY KEY, ROOMTYPE VARCHAR(9), DAILYRATE NUMERIC(20), STATUS CHAR(1))";
String createBooking = "CREATE TABLE BOOKING (BOOKINGID NUMERIC(10) NOT NULL PRIMARY KEY, ROOMNO NUMERIC(5), PROPOSEDCHECKINDATE DATE, PROPOSEDCHECKOUTDATE DATE, CHECKEDIN CHAR(1), ACTUALCHECKINDATE DATE, CHECKEDOUT CHAR(1), ACTUALCHECKOUTDATE DATE, CANCELLED CHAR(1), CANCELDATE DATE, CANCELREASON VARCHAR(100),AMOUNT NUMERIC(20), PAYDATE DATE, PAYMODE VARCHAR(15), STATUS VARCHAR(50), PAID CHAR(1), DATE DATE, CUSTOMERID NUMERIC(15))";
String refOne = "ALTER TABLE BOOKING ADD FOREIGN KEY(CUSTOMERID) REFERENCES CUSTOMER(CUSTOMERID)";
String refTwo = "ALTER TABLE BOOKING ADD FOREIGN KEY(BOOKINGID) REFERENCES BOOKING(BOOKINGID)";
Date one = new Date(20/9/2014);
Date two = new Date(10/10/1010);
Date three = new Date(16/9/2014);
Booking book = new Booking();
book.SetBookingID("9879974564");
book.SetRoomNumber("001");
book.SetProposedCheckInDate(one);
book.SetProposedCheckOutDate(one);
book.SetCheckedIn('F');
book.SetActualCheckInDate(one);
book.SetActualCheckOutDate(one);
book.setCancelled('F');
book.SetCancelDate(two);
book.SetCancelReason("");
book.SetAmount(10.20);
book.SetPayDate(one);
book.SetPayMode("Bank Deposit");
book.SetStatus("Done");
book.SetPaid('T');
book.SetDate(three);
book.SetCustomerID("9112315190086");
String insertStatement = ("INSERT INTO ROOM(ROOMNO, ROOMTYPE, DAILYRATE, STATUS) VALUES (001, 'Single', 120.00, 'A')");
String insertStatementTwo = ("INSERT INTO ROOM(ROOMNO, ROOMTYPE, DAILYRATE, STATUS) VALUES (002, 'Single', 120.00, 'A')");
String insertStatementThree = ("INSERT INTO ROOM(ROOMNO, ROOMTYPE, DAILYRATE, STATUS) VALUES (003, 'Double', 230.00, 'A')");
String insertStatementFour = ("INSERT INTO CUSTOMER(CUSTOMERID, LASTNAME, FIRSTNAME, GENDER, EMAIL, CREDITRATING, NATIONALITY, DATEOFBIRTH, PHONE, CELLPHONE) " +
"VALUES (9112415190086, 'Nel', 'Piet', 'M', '[email protected]', 'Good', 'America', '31/12/2014', 0721360363, 0721589859)");
String insertStatementFive = ("INSERT INTO CUSTOMER(CUSTOMERID, LASTNAME, FIRSTNAME, GENDER, EMAIL, CREDITRATING, NATIONALITY, DATEOFBIRTH, PHONE, CELLPHONE) " +
"VALUES (9112315190086, 'van Tonder', 'Hannes', 'M', '[email protected]', 'Good', 'South Africa', '31/12/2014', 0711360193, 0791589789)");
String insertStatementSix = ("INSERT INTO CUSTOMER(CUSTOMERID, LASTNAME, FIRSTNAME, GENDER, EMAIL, CREDITRATING, NATIONALITY, DATEOFBIRTH, PHONE, CELLPHONE) " +
"VALUES (9115987489968, 'le Roux', 'Paul', 'M', '[email protected]', 'Good', 'South Africa', '31/12/2014', 0721361193, 0821589789)");
try
{
Connection conn = DriverManager.getConnection(createDB);
Statement stmt = conn.createStatement();
}
catch(Exception ex)
{
}
conn.close();
I suspect that maby I would have to add another statement in my try block.
When I debug my program the problem lies at this statement:
Connection conn = DriverManager.getConnection(createDB);
when the program should execute that statement it goes to the catch and throw the error message.
