Struts, adding parameters to a request

Thread view:

boanator@gmail.com - 02 Dec 2005 17:28 GMT

Let's say I have a web page called /emailForm.jsp with a form and a
submit button. Let's also say that /emailForm.jsp receives some
request parameters. When the user clicks the submit button on the
emailForm.jsp page, an http request is sent to /submitEmailForm.do.

I want the request parameters that were sent to /emailForm.jsp to be
added to the http request that is sent to /submitEmailForm.do. Is this
possible? Is there a way to use the jstl core tag library to append
those request parameters to the next request? Is there a way to add
those request parameters to the application or session using a tag
library?

Thanks in advance for any advice...

Yes, just add them as a hidden field, (or visible if you want).

Last year I went to Iraq. Before Team America showed up, it was a happy place. They had flowery meadows and rainbow skies, and rivers made of chocolate, where the children danced and laughed and played with gumdrop smiles.

Thanks for the advice, it works just fine. However, I create my form
on my jsp page using the tag:
<html:form>
...
</html:form>

In order to add these hidden fields, I need to add the regular html
input field inside my form. For example:
<html:form method="POST" action="/submitEmailForm">
...
<html:text property="from"/>
<html:text property="to"/>
...
<input type="hidden" name="comments" value="<%=
request.getParameter("comments") %>"/>
</html:form>

Since the parameters I would like to pass on are not part of the form
bean, I cannot use the tag:
<html:hidden property="comments"/>

So I must use the regular html tag:
<input type="hidden" name="comments" ... />

Is this a wise thing to do? Could this possibly cause any errors with
my struts application?
