There is a row which has 2 fields
<td >燭icket No</td> <td >燘ill No</td>
<td ><input type="text" name="<%= ticketNo+ %>" value="" size=10></td>
<td ><INPUT TYPE="TEXT" NAME="<%=billNo+"%> value="" size=10></td>
I want to pass the values entered in the row along with one hidden value called as rowId. The rowId is attached to the ticketNo and billNo values.
How to do this?.........Plz Help
Any idea , if there are many rows?
You can use input of hidden type and place it next to your ticketno or billno input tag.
it will not visible in your page or disturb your table layout when output to browser.
Since it's hidden, you can omit the size="".
<input type="hidden" name="" value="">
Hope it helps.
All fields of input type text and input type hidden will be sent along with the request when the user submits the form. There is really no difference between a text field and a hidden field other than the fact that the hidden one is not displayed on the page.
So you should be all set. Just use HttpServletRequest.getParameter() to retrieve the values on the server side.

[nobr]Here is a basic servlet that reads three parameters from a form. One of the is hidden. You can see that its no different from reading non hidden form fields.
