We ignore it because many of the results will fail, such as the redirect, when you try to run them after the page has started to render.

Sounds quite logical (I'm not a JSP expert (yet ;-))

You can do a ww:include to include a template, if you like...

There is no include tag in WW2... A bug? I could use the standard JSP include, or port it over from WW1.

Hi,
My app is very simple, I don't think an example would add anything
useful. Besides that I found out that the JavaDoc of ActionTag states:
ActionTag enables developers to call Actions directly from a JSP page
by specifying the Action name and an optional  namespace.  The body
content of the tag is used to render the results from the
Action.  Any
Result processor defined  for this Action in xwork.xml will
be ignored.
Does the above mean that results are no further processed? Does this
include ERROR as well? What could be the use of that? I guess
defining
nothing in xwork.xml for a certain action would achieve that (==no)
result, so why actively ignore it?

Can you send an example app?

Thanks,

Your xwork.xml looks ok... What's it doing again?

If you post to it from a form it works, but if you hit it
as a URL it
doesn't?

Sorry, I don't remember the details...
Here's a snippet from my main jsp page:

<ww:action name="login" id="login" namespace="/" />
<ww:form name="myForm" action="login
.action" method="POST">
        <input type="submit" value="Submit"/>
</ww:form>
The first action doesn't do anything, the second one works.

If you map a JSP page using the "dispatcher" result, this
should work,
right? Or am I missing something?
I tried to do this, because this seems the logical thing
to do (just
as in WW1). However nothing happens. Could someone tell me
if there
are any errors in my xwork.xml?

*snip*
(I placed login.jsp in the root of my .war; the jsp can be
executed
when I go to the URL directly.)
The 'funny' thing is that when I have my action executed from a
simple WW form, the action result is processed. Is this
difference
intentional? (Which would mean that what I want is not possible?)

You can also add a global-result for "login" and have an
interceptor
that checks your login stuff and returns "login" without
executing the
rest of the action, and it will always go to that JSP.
I will look into this. Seems quite elegant to take
someone to the
login page when he wants to execute an action that
requires login.
(This is possible when using JAAS and form based login, btw.)

Hi,

In webwork 1 it is possible to include a JSP page in
another by
setting the result of an action to a particular JSP.
This way you
could program in a condition in your action. For example
display a
page with a login
form, if the user is not logged in, and a logout page
if she is.
How can this be done in webwork 2, without coding the
condition
into the jsp page (using if's)? Ultimately I want to use an
interceptor to
code the condition, and thus short-circuit the action.
For example:
[begin main page]

<ww:action name="user_messages" />

[/end main page]

Is this possible; what do you think?

Regards, Hendrik
