simple question

[mo...@dit.unitn.it]

Hi, there is a possibility to send an object in the request if i don't pass it
with parameter of the link?
for example:

<% 
request.setAttribute("in","index");
....
%>
...
<hm:link page="/index.jsp" transaction="true">
	home
</hm:link>

this obviously don't work...but there is a system to obtain this whit a Struts
component?
I should pass a String value to action, but this must be not visible in the url.
In particular my action don't know the page that call it and for this... 
I try to pass it as message, but this don't work..
Any idea?
Thanks in advance
Alessio

You don't need an ActionForm (but you can).

You can use request.getParameter("in") in your action, you can use a
dynaForm too if you don't wan't to create a formBean for this.

As you can read in the code I sent, I did not used <html:form>, so
action form definition is not needed. This beeing said, using a
dynaForm an struts tags would be IMHO the cleaner way, and you will
not have to create the code for a new formbean.

You can try this :

<form name="myLink"
      action="<html:rewrite page="/index.jsp"/>"
      method="POST">
   <input type="hidden" name="in" value="...">
</form>

<a href="javascript:document.forms.myLink.submit()">home</a>

Notice the (not visible) HTML form will add a visual line break in
browser. You can avoid it by putting it a page bottom or in an hidden
div, or between two rows of a table.
