On the Delete issue, you could do a server-side rewrite of a link that invokes an action to delete a row as in:
<a href="http://localhost:8080/mywebapp/deleteRow.do?recordNum=10";>Delete Me</a>
That's just a basic GET form request.
Again, find a good book, do some reading.

Thanks David for the solution. To be frank, i really don't know how to code it. Will you give a sample code snippet? I'm using apache2, tomcat 5.5.7 on Win 2K machine.
One more problem. I've a form and also submit button. I've number of text fields in it. On entering some data and focus losts from that field, i call a javascript function, i set number of hidden values and call a JSP using location.href of Javascript. But hidden values are not getting passed to jsp.I'm getting null. Why? How to overcome this? Pls help.
One more requirement what i've is: i'VE A FORM WITH FORM ELEMENTS IN IT AND A 'aDD'
BUTTON. After filling theform, if the user clicks on
'Add' button, the contents gets added aas row into a
HTML table located below that form. That way user can
add n number of rows to the bottom table. In the
table, i need a 'Delete' button. After selecting any
row, if the user clicks on 'Delete' button, it should
get deleted from the table. I guess it can be
possible. But it's a big challenge to me as i know
only ABCD of HTML & Javascript.
If anybody can direct me to a good HTML/Javascritp forum also fine. If i get a solution directly, it's wonderful.
Thanks a lot. Sorry again if it's not the right place to post this.

The best advice I can offer -- have a javascript
that does the submit for you on the event the drop-down changes state. Then let a servlet handle storing your form data in the session and
passing updated data to the next page. Outside of something like that, I
think you'll need to incorporate a submit button.

page.
Wel this might help...
// You write following two lines in first JSP
theString name = "Java";// This might be your hidden field. session.setAttribute("HiddenName", name);
//Then you get the name on next page as follows.
String userName = (String)session.getAttribute("HiddenName");
The "name" attribute will be available throught
pagehttp://members.fortunecity.com/javaclub/shakeel.htmsession life, unless we remove it explicitly or restart Tomcat. We can use it on any page once it is placed properly.

If you are developing a JSP/Servlet then you cando
this by keeping those variables in session.

Ah-ha, somehow I changed a line in the

...so changing it back (which is how it was
out-of-the-box after
jk_1.2.8.exe was run) to:
/jsp-examples/*=ajp13w
...fixes it, and I can now access both

I now get the expected results for:

Now I can add docabses to my heart's content - *relieved sigh*
SO...the easy answer is a simple, single CONTEXT
