            boolean flag;
            for(flag = false; resultset.next(); flag = true)
                i++;
                SerialNo = resultset.getString(2);
                printwriter.print((new StringBuilder()).append("<table><tr><td> ").append(i).append("</td>").toString());
                printwriter.print((new StringBuilder()).append("<td> ").append(SerialNo).append("</td></tr></table>").toString());
            if(!flag)
                printwriter.println("<h1> No records selected </h1>");
        catch(Exception exception)
            System.out.println((new StringBuilder()).append("SQLException: ").append(exception).toString());
    static String empid1;
    static String empid;
    static String SerialNo;
    static String designation;
}thanks in advance. i just feel there is something to be done with connection string.
