How to connect to Access .mdb database from 64-bit Java?

Question

Hi I have the below code to connect to MS Access database on Windows 7 OS. I have changed the Data Source short cut to point to 64bit odbc then 32 bit. But still getting the error as

java.sql.SQLException: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
    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 TestDBConnection.main(TestDBConnection.java:21)

And my code is :

import java.sql.Connection;
import java.sql.DriverManager;

public class TestDBConnection {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        try
        {
            System.out.println("filename");
            Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
            String database = 
                      "jdbc:odbc:DRIVER={Microsoft Access Driver (*.mdb)};DBQ=C:\\Test\\Tests.mdb";
            Connection conn = DriverManager.getConnection(database, "", "");
        } catch(Exception ex) {
            ex.printStackTrace();
        }
    }

}

How ever I have SQL Workbench tool through which I can connect to it but not through java code.

Please need help badly as I am struggling with this from past 3 hours searching on Google.

Answer 1

If your Java app is running in a 64-bit Java Virtual Machine (JVM) then DRIVER={Microsoft Access Driver (*.mdb)} is not going to work because there is no 64-bit version of the Jet database engine. You can...

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

... or ...

• Run your Java app in a 32-bit JVM and continue to use the existing DRIVER= string. The related answer here might prove helpful if you choose this option.

... or ...

• Use the UCanAccess JDBC driver for Access databases. It is a free, open-source, pure Java implementation so it works on both 32-bit and 64-bit systems, both Windows and non-Windows. It also works with Java 8 (which has dropped the JDBC-ODBC Bridge). For more details, see:

Answer 2

You can install the 64 ODBC drivers for Access available from Microsoft
