[OT] parameter vs. attribute?
Hello all,
here is a question:
I have some links on my page which are of the form href="/blah.do?id=15"
Thus my id is exposed in the link and it is a request parameter.
How would I hide this id and how would I forward it as a request attribute?
Thanks,
Denis

That would write a simple one-button form to submit the id property. If
the ActionForm property was set to "15" before forwarding to the page,
then,yes, it would be the equivalent of the link.
Or, you could have a link too. See the html:link tag.

Hm.... Does the form change across the request from action -> jsp -> action?
Then I could have <a href="/myNextAction.do">Press here</a>
and I would still get the form with the id in it in my next action
(assuming that I associate the form as input in the struts-config)?

What ever struts does it will have to write a standard hidden tag to the
client, ie name and value, so no, you can't hide the id.
Attributes are internal server side objects, they don't get sent to the
client.
All a client can do is send parameters by GET or POST.
AFAIK.

So, if I am understanding this correctly, instead of the link I would
have to have something like:
<html:form action="myNextAction.do" >
<html:hidden property="id"/>
<html:submit value="press here"/>
</html:form>
Assuming that I put id into the associated ActionForm in the previous
action?

The Struts model is that you would define id as a property on your
ActionForm. The controller will then populate the property for you
automatically, using reflection. In the Action, you can then retrieve he
property using getId().
MyForm myForm = (MyForm) form;
String id = myForm.getId();
The page itself would not change. There are Struts custom tags that can
help you create references like that dynamically, but the tag would
appear the same in the browser's HTML.

[OT] Chetan Khimjee
Posted by Denis Avdic <de...@betterway.net>.
Chetaan needs to empty his mailbox!
Next time he does (meaning whenever someone posts and does not get this
message) email chetan directly
and kindly (or otherwise) ask him to either empty his mailbox regularly
or to subscribe to digest version....
grrrr.
