How to store data in a file without using DB

Question

Hi all
I want to develop a small application that could contain at most 10000 records, so if it is possible I want to store the data in a file, therefore the installation of the application can be simplified and the users don't need to add a ODBC dataSource in the control panel before running the program.
If the above is not possible. Does anyone know how to use Java to programmatically add a ODBC dataSrouce in the control panel in the Windows Platform?
Thank you very much !
Kind Regards
Edmond

1 ) Save the records into a vector and write it to a file. You will have to load all the records when you read the file though.
2 ) Use a dsn-less connection. You do not need to have a dsn set up and you can access a file using the bridge driver:
url = "jdbc:odbc:Driver={Microsoft Excel Driver (*.xls)};DBQ="+file.getPath();
               //Obtain the driver for the
               Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
               //Create the connection
               con = DriverManager.getConnection(url, "", "");
               //Ensure that the connection allows two way commands
               if (con.isReadOnly()) con.setReadOnly(false);
               //Create the statement to be executed
               stmt = con.createStatement();
     //execute the select statement
               ResultSet rs = stmt.executeQuery("SELECT * FROM \"Sheet1$\"");
This should work, let me know if it dwosnt
