    Default Error connecting to database

    while trying to import some data from my accessing MS Access 2010 to a mySQL server i receive this error:

    [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified

    below is my code for the connection:

     String user = "root";
          String pwd = "pass";  
          String driver = "com.mysql.jdbc.Driver";
          String url = "jdbc:mysql://localhost:3306/newspaper";  
    try
           {
           	Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
           	String filename = "C:/JUN2011.mdb";
    String database = "jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ=";
    database+= filename.trim() + ";DriverID=22;READONLY=true}"; // add on to the end 
    // now we can get the connection from the DriverManager
    Connection conn = DriverManager.getConnection( database ,"",""); 
     
            Class.forName(driver);
            Connection con = DriverManager.getConnection(url, user, pwd); 
            Statement stmt = con.createStatement();
    		Statement access=conn.createStatement();

    when i run the code in Win XP everything was working perfectly... but once i run it on Win 7.. the error came out..
    i am using;
    MySQL 5.5 server, MS Access 2010(on Win 7)/MS Access 2003 (Win XP).. my IDE is JCreator Pro 4.5
    OS: Window 7 x64bits Ultimate/ Windows XP Pro SP2

    For MS Access, you need to define a data source. Maybe you defined it on WinXP but not yet on Win7.

    Oh, sorry, I have just realized that, so are you sure that the file path is correct? Maybe it is moved around somewhere when you change to Win 7.

    1. Is java 32-bit installed on your machine?
    2. You have to create DNS by following,
    a). Go to Program Files (x86), System Files,(somewhere, i don't know the exact path) Find for odbcad32.exe and double click
    3. Now create DNS and again execute the code.

    do u mean DNS or DSN? as i could not find any DNS in the odbcad32.exe

    oh and i sure java is being install as the connecting to mySQL is fine... the error only occur when i try to connect to MS Access...
