Question

I’m trying to study for a basic SQL test at school but unfortunately I copied the class that we are supposed to use into a project on my pc and I am getting the following error:

java.sql.SQLException: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified

package Question1;

// Your name, Q 1
import java.sql.*;
import java.io.*;
import javax.swing.*;

public class GreenWood
{
 // Set up database connection
   private static final String DATABASE_FILE_NAME = "WoodDB.mdb";
   private static final String DRIVER = "jdbc:odbc:DRIVER=" +
   "{Microsoft Access Driver (*.mdb)};" +
   "DBQ=" + new File (DATABASE_FILE_NAME).getAbsolutePath ();
  static
  {
     try
     {
        Class.forName ("sun.jdbc.odbc.JdbcOdbcDriver");
     }
         catch (ClassNotFoundException e)
        {
           System.out.println ("Class not found");
           e.printStackTrace ();
        }
  }


  private Connection dbcon;
  private BufferedReader keyb = new BufferedReader (new InputStreamReader (System.in));

   public GreenWood ()
  {
     System.out.println ("WoodDB Connection");
     try
     {
        dbcon = DriverManager.getConnection (DRIVER);
        Statement stmt = dbcon.createStatement ();
        System.out.println ("Connection successful\n");

        char choice = ' ';
        do
        {

         //Prints options for user input

           choice = keyb.readLine ().toUpperCase ().charAt (0);
           System.out.println (" ");
           switch (choice)
           {
             //calls query methods based on user input

           }
        }
        while (choice != 'X');
        dbcon.close ();
        System.out.println ("Done");
        Thread.sleep (1000);
        System.exit (0);
     } // try
         catch (Exception e)
        {
        // process exceptions here
           System.out.println ("Connection unsuccessful");
           e.printStackTrace ();
           System.out.println (e.toString ());
        }
  } // HoutSoorte constructor

  //Query Methods
  //Main creates new instance of GreenWood

my WoodDB database is located in the root project directory.

I Have done some troubleshooting and I believe that the problem is the URL of the driver location;

dbcon = DriverManager.getConnection (DRIVER);

DRIVER being:

private static final String DRIVER = "jdbc:odbc:DRIVER=" +
   "{Microsoft Access Driver (*.mdb)};" +
   "DBQ=" + new File (DATABASE_FILE_NAME).getAbsolutePath ();

After about an hour of research I’m still just as confused as I was.
If anyone can help this nub programmer(me) by explaining the problem in baby words and how I can fix it, it would be ever appreciated.

Try using 32-bit JVM. I am getting the same error message when trying to connect from 64-bit JVM.
