WHAT'S GOING ON!!!? JDBC Statement Problems

Question

Sorry about the 2 previous posts, I kept getting an error when I tried to submit my thread saying that it could not be posted, but obviously it could!!
Anyway can anyone help me? One of my JSP's refuses to execute properly so I presume there is something wrong with the associated methods in my connector.java file. Everytime I try and run my JSP in TomCat it produces the error message "java.sql.SQLException: java.sql.SQLException: General error, message from server: "Table 'talboothdb.roomsoccupied' doesn't exist". The MySQL statements I am using work fine when typed directly into MySQL via the Command Prompt so I know they arn't the problem. Can anyone see where I am going wrong?
The neccessary connector java and the JSP I am using are displayed below,
package javaclass;
import java.sql.*;
import java.util.*;
public class connector{
  String error;
  Connection con;
  ResultSet rs = null;
  int success;
  public connector()   { }
  public void connect() throws ClassNotFoundException,
                           SQLException,
                           Exception {
       try
            Class.forName("org.gjt.mm.mysql.Driver").newInstance();
            con = DriverManager.getConnection(
                 "jdbc:mysql://localhost:3306/talboothdb","","");
            } catch (ClassNotFoundException cnfe) {
                 error = "ClassNotFoundException: could not locate DB driver";
                 throw new ClassNotFoundException(error);
            } catch (SQLException cnfe) {
                 error = "SQL Exception: Could not connect to database.";
                 throw new SQLException(error);
            } catch (Exception e) {
                 error = "Exception: An unknown error occured while connecting to DB";
                 throw new Exception(error);
       public void disconnect() throws SQLException {
            try {
                 if ( con != null ) {
                      con.close();
            } catch (SQLException sqle) {
                 error = ("SQLException: unable to close the DB connection");
                 throw new SQLException(error);
public void roomsBooked(String arrivalDate, String departureDate)
                              throws SQLException, Exception {
            if (con != null) {
              try {
                PreparedStatement checkBookings;
                checkBookings = con.prepareStatement
                     ( "CREATE TEMPORARY TABLE roomsoccupied "
                    + "SELECT roombooked.room_id FROM roombooked, booking "
                    + "WHERE "
                    + "roombooked.booking_id = booking.booking_id "
                    + "AND "
                    + "booking.arrival_date <  '?' "
                    + "AND "
                    + "booking.departure_date >  '?' "
                checkBookings.setString(1, departureDate);
                checkBookings.setString(2, arrivalDate);
                checkBookings.executeUpdate();
              } catch (SQLException sqle) {
                error = ""+sqle;
                throw new SQLException(error);
            } else {
              error = "Exception: Connection to database was lost.";
              throw new Exception(error);
     public ResultSet roomsAvailable()
                              throws SQLException, Exception {
            if (con != null) {
              try {
                PreparedStatement checkAvailability;
                checkAvailability = con.prepareStatement
                     ( "SELECT rooms.room_no FROM rooms "
                    + "LEFT JOIN roomsoccupied ON rooms.room_no=roomsoccupied.room_id "
                    + "WHERE roomsoccupied.room_id IS NULL;"
                checkAvailability.executeQuery();
              } catch (SQLException sqle) {
                error = ""+sqle;
                throw new SQLException(error);
            } else {
              error = "Exception: Connection to database was lost.";
              throw new Exception(error);
         return rs;

bluey_the_punch, why are you so wedded to this CREATE TEMPORARY TABLE? In an earlier thread it was recommended that you see if this can be managed with a JOIN. Did you at least try it?
I see you added PreparedStatement, but you didn't implement it correctly. You certainly don't need to put single quotes around the question marks in the SQL. I'd also recommend that you make those columns dates in your database and use setDate() to bind the values. Strings compare much differently than dates do. If you're not getting the expected results, that might be why.
It just looks like you've blown off the advice you've gotten so far and just keep asking the same question in hope of getting the answer you want to hear. JMO - MOD
