This is a typical error when using the MS Access database through the poor JDBC-ODBC bridge driver and retrieving the same data more than once from the result set. You need to retrieve the data once and assign it to a variable and use the variable multiple times instead.

while (rs.next()) {
    String flatNo = rs.getString("Flat_No");
    buffer += "<option value='" + flatNo + "'>" + flatNo + "</option>";   
}

Unrelated to the concrete problem, doing this in a JSP file is a bad idea. See also Show JDBC ResultSet in HTML in JSP page using MVC and DAO pattern for another concrete example how to do it the proper way.
