Follow these steps:

1)Go to the start->Control Panel->Administrative Tools-> data sources.

2)Click Add button and select the driver Microsoft Access Driver(*.mdb).

3)After selecting the driver, click finish button.

4)Then give Data Source Name and click ok button.

5)Your DSN will get created.

6) Restart your compiler and compile your java code.

For Inserting Data:

import java.sql.*;
class AccessDatabase{
    public static void main(String[] args){
        try{
           Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
           Connection con = DriverManager.getConnection("jdbc:odbc:student");
           Statement st=con.createStatement();
           String name="roseindia";
           String address="delhi";
           int i=st.executeUpdate("insert into user(name,address) values('"+name+"','"+address+"')");
           System.out.println("Row is added");
           }
        catch(Exception e){
            System.out.println(e);
        }
    }
}
