Heya all,

I am having some issues and maybe someone has an answer for me!

I am trying to read write some *DBF table from a java application. I have found this code :

try
        {
            Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
            String connString="jdbc:odbc:Driver={Microsoft dBASE Driver *.dbf)};DefaultDir=C:\\test";//DefaultDir indicates the location of the db
            Connection connection=DriverManager.getConnection(connString);
            String sql="SELECT * FROM table_name where condition";// usual sql query
            Statement stmt=connection.createStatement();
            ResultSet resultSet=stmt.executeQuery(sql);
            while(resultSet.next())
            {
                System.out.println();
            }
            System.out.println();
        }
        catch (ClassNotFoundException e)
        {
            e.printStackTrace();
        }
        catch (SQLException e)
        {
            e.printStackTrace();
        }

Open in new window


This code is working fine with a 32-bit version of windows but when I try on 64 bit, it gives me the error :

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

I have looked it up and the best answer found was about something to do with playing with the DNs in system32 or sysWOW64 but I wasent able to get threw it or my understanding was no good enough....

Here is the link with that answer:

Is there a simple solution to my problem?

You need 64 bit driver for Microsoft Office which is available e.g. here: http://www.microsoft.com/en-us/download/details.aspx?id=13255

You have to use c:\windows\system32\odbcad32.exe to check whether or not the driver is installed. It will also tell the exact driver name used for connection string. I would guess the name is   Microsoft Access dBASE Driver (.dbf, .ndx, .mdx).

Already tried updating the 64 bit driver with no further success.

So the driver is present? What version?  Or did the update failed?

Same one has the code mentioned higher:

String connString="jdbc:odbc:Driver={Microsoft dBASE Driver *.dbf)};DefaultDir=C:\\test";

OK. That explains your problems probably.

{Microsoft dBASE Driver *.dbf)} does not describe the 64 bit driver. This one is available in the 32 bit version only.

You have to look for the correct 64 bit driver name as described in my first answer.

This is correct driver name. If you see it from ODBC administrator executed from c:\windows\system32\odbcad32.exe then create a DSN (named e.g. myDSN) from this driver and test it with the following connection string:

String connString="jdbc:odbc:myDSN" ;

Great!  I believe it should also work without DSN...

Something like:

String connString="jdbc:odbc:Driver={Microsoft Access dBASE Driver (*.dbf, *.ndx, *.mdx )};DefaultDir=C:\\test";
