Prob..in search.. urgent..

Question

i have a problem in the search record from the database..actually my prob is that when user enter a string, if that string found in that particular field in database then it displays values in the jsp page..(this part is working) but if the record of that particular entry is not found in database it should display error...(this part is not working)
my code is as follow:
String enter = request.getParameter("enter");
sql = conn.prepareStatement("SELECT * FROM pay_header,pay_detail where pay_header.vou_no=pay_detail.vou_no and pay_header.vou_no like 'JV%'  and pay_header.vou_no = '" + enter + "'");
results1 = sql.executeQuery();
while(results1.next()) {
vou_no = results1.getString("vou_no");
pay_post = results1.getString("pay_post");
pay_narr = results1.getString("pay_narr");
chq_no = results1.getString("chq_no");
out.println("<FIELDSET>");
out.println("Voucher No: <input type='text'  size=9 value='" + vou_no + "' readonly>");     
out.println("</FIELDSET>");
}

hi abhith ,
What i understand from ur posting is,
You just need to display an error msg when the resultset is empty.
Then you can do this way,
results1 = sql.executeQuery();
if(! results1.next()) throw new SQLException("Sorry No Record Found");
//the rest comes here.
Now in the jsp page either you can cath it and display, or use errorPage .
I hope this may help you.
Post me if this is not the thing you want.
