Re: Progamatically setting values of FORM elements

[Dennis Dai]

Well it's not part of the servlet spec and certainly should not be IMHO.
What you can do is to create a bean which sets those parameters from the 
request, and pass it to the resulting JSP page. Then in the JSP page you 
use getter methods (or EL variables) to populate those parameters. This 
is usually used when there're errors in the submitted form and I'd 
assume you're going to use it with the same purpose.

Various web application frameworks like struts or webwork/xwork will do 
this automatically for you. (I'm using webwork/xwork right now and IMHO 
it's much less complicated and more elegant than struts.) If you're 
using your home grown framework, you can at least borrow ideas from 
those other frameworks ...

There is no way that I know of to do the reverse, set those parameters on the response 
and it will apply to the form elements.
The browser stores the element values somewhere, just thought it might have been 
floating around somewhere I could get it.
I thought someone would know something I did not.

Hi,
No, the Servlet API has no concept of HTML.

From the responses, I am guessing there is not a way to do this with
only
the Servlet API?
I am not currently using struts and learning to use them, implementing
them
at this time, I think would be too much of a headache.
I'll have to find an alternate solution that fits into our own
framework.
Thanks...

Subject: Progamatically setting values of FORM elements
Is there any way I can have my java set the values of FORM elements.
Rather than storing the values in the java code and generating the
complete
form element containing that value.
Something like adding something to the response that will give that
item a
value.
For my particular need, I want to set a number of checkbox elements on
or
off. I do have the ability to predict the element names...
