Java Access DB Connection

Question

I try to make project with connection to db (MS Access 2010) I use this tutorial on CodeProject.

import java.sql.*;

public class DbAccess
{
    public static void main(String[] args)
    {
        try
        {
            Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
            String database = 
              "jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ=myDB.mdb;";
            Connection conn = DriverManager.getConnection(database, "", "");
            Statement s = conn.createStatement();

            // create a table
            String tableName = "myTable" + String.valueOf((int)(Math.random() * 1000.0));
            String createTable = "CREATE TABLE " + tableName + 
                                 " (id Integer, name Text(32))";
            s.execute(createTable); 

            // enter value into table
            for(int i=0; i<25; i++)
            {
              String addRow = "INSERT INTO " + tableName + " VALUES ( " + 
                     String.valueOf((int) (Math.random() * 32767)) + ", 'Text Value " + 
                     String.valueOf(Math.random()) + "')";
              s.execute(addRow);
            }

            // Fetch table
            String selTable = "SELECT * FROM " + tableName;
            s.execute(selTable);
            ResultSet rs = s.getResultSet();
            while((rs!=null) && (rs.next()))
            {
                System.out.println(rs.getString(1) + " : " + rs.getString(2));
            }

            // drop the table
            String dropTable = "DROP TABLE " + tableName;
            s.execute(dropTable);

            // close and cleanup
            s.close();
            conn.close();
        }
        catch(Exception ex)
        {
            ex.printStackTrace();
        }
    }
}

But i get strange Exception : java.sql.SQLException: [Microsoft][????????? ????????? ODBC] ???????? ?????? ?? ?????? ? ?? ?????? ???????, ???????????? ?? ?????????

java.sql.SQLException: [Microsoft][????????? ????????? ODBC] ???????? ?????? ?? ?????? ? ?? ?????? ???????, ???????????? ?? ????????? at sun.jdbc.odbc.JdbcOdbc.createSQLException(JdbcOdbc.java:6956) at sun.jdbc.odbc.JdbcOdbc.standardError(JdbcOdbc.java:7113) at sun.jdbc.odbc.JdbcOdbc.SQLDriverConnect(JdbcOdbc.java:3072) at sun.jdbc.odbc.JdbcOdbcConnection.initialize(JdbcOdbcConnection.java:323) at sun.jdbc.odbc.JdbcOdbcDriver.connect(JdbcOdbcDriver.java:174) at java.sql.DriverManager.getConnection(DriverManager.java:579) at java.sql.DriverManager.getConnection(DriverManager.java:221) at dbaccess.DbAccess.main(DbAccess.java:28)

I google it and find other questions on Stack like this : Stack Post

So i add all ODBC drivers that can help me connect *.mdb file. But nothing good hepend.(

What is it and how connect to Access DB?

Answer 1

There is nothing fundamentally wrong with your code because I pasted it into Eclipse and it ran fine. The only change I made was to specify the path to the database file, i.e., instead of using

DBQ=myDB.mdb

I used

DBQ=C:\\__tmp\\myDB.mdb

I was also running it under a 32-bit JVM (on a 32-bit computer). So, my suggestions would be

1. Try specifying the complete path to the .mdb file like I did.

2. If you still get an error, check your Java environment to see if your application is running in a 64-bit JVM. If it is, then Driver={Microsoft Access Driver (*.mdb)} will not work: there is no 64-bit version of the older Jet ODBC driver. In that case you have two options:

   i. Configure your application to run in a 32-bit JVM, or

   ii. Download and install the 64-bit version of the Access Database Engine from here, and then use Driver={Microsoft Access Driver (*.mdb, *.accdb)}.
