Re: How to send hidden variables to next page
I dont know but looks like you are doing somethings wrong... hidden
fildes are a great choice... better them use GET method...
About the table think... use Iframe and do a submit to it...
Whem you submit you use normal submit button or javascript???
If you are submiting with normal button try to use Javascript is much
better! Example:
!-- AT HEADER --
script language=javascript
function submitform()
{
// FOR LOCAL FORM... where the form name is myform
document.myform.submit();
//OR FOR IFRAME FORM... where the IFRAME name is myframe and the FORM
name is myform1
window.frames.myframe.document.myform1.submit();
}
/script
!-- AT BODY
The link to submit:
--
A HREF=javascript: submitform()SUBMIT HERE!!!/A
You can also make MANY variations on it... like pass values in the
function from the external frame to a filed on iframe.
Example:
!-- AT HEADER --
script language=javascript
function submitform(val1)
{
//CHANGE THE VALUE OF A FIELD ON IFRAME... where myfield is the name of
the filed...
window.frames.myframe.document.myform1.myfield.value=val1;
//FOR IFRAME FORM... where the IFRAME name is myframe and the FORM name
is myform1
window.frames.myframe.document.myform1.submit();
}
/script
!-- AT BODY --
A HREF=javascript: submitform(VALUEOFF1)SUBMIT HERE/A
I make some dynamic tables based on users choies! Works very well.

It's just i'm using one hidden variable named
'package' which was doing all the problem. I just
changed it to something else and now it's working.
Still table issue not solved. I'm gooling ... for the
solution.

Amazon. They even support a rating scheme where
people can voice their

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.

Thanks for the answers Shakeel.
My problem is, i've a page that doesn't have
submit
button. I need to send the hidden variables in
that
HTML page to next HTML page. Here the hidden
value
is
set based on the type of option selected from
'select'
drpo down box in HTML. To put it in session, i
need
to
identify the selected option and assign it to
java
varialbe. I don't think it's possible to assign a
javascript variable to java variable. Pls help to
solve this problem.

Users Rigths
Hi, I'm new in tomcat and Java. I search at the archives and do some google but I dont find any think like that... I would like to create a user at tomcat with the rights like to deploy remotely and reload their aplication... but ONLY their own aplication and dont have access to the global manarger or admin. (Kind a especific manager and admin per aplication... if possible even a restricted set of tools) I dont know if I'm going to the wrong direction... and tips are very welcome...
