No problem. An example is the mod-db sample sitemap. (In scratchpad for

Not sure whether nesting works with action-sets, though.

Apart from the comment this looks reasonable.
I have tried to get this working but without any luck.
Does an error show up in your logs?

It works just like it was mentioned with redirects or calls.

AW: how do I redirect in an Action?
Nested actions work - at least for me.
Anyway, the xml snippet you send isn't valid: your second map:act is an
empty tag but several lines down you close it the second time.

RE: how do I redirect in an Action?
It totally depends on what you want to replace with your resource...
if you have the pipeline like:
==
map:pipeline
...
...
map:match pattern=page1.html
map:generate src=page1.xml/
map:transform src=pageTohtml.xsl/
map:serialize type=html/
You can change this to the following:
=
map:resources
map:resource name=standard
map:transform src=pageTohtml.xsl/
map:serialize type=html/
/map:resource
/map:resources
map:pipelines
map:pipeline
...
...
map:match pattern=page1.html
map:generate src=page1.xml/
map:call resource=standard/
/map:match
...
/map:pipeline
..
/map:pipelines
The advantage is that if you change the stylesheet pageTohtml.xsl you only
have to change it in one place.

Thanks for all the suggestions. I'm pretty confused at this point, as I
haven't used map:resource or map:select previously, so I need to spend
some time understanding the code you've offered. One thing in particular I
don't see is where I should put my normal generate, transform, and
serialize steps for the protected URL. Do they just go after the call to
the resource?
-Christopher
Hi Christopher and Edgar,
Couple things. I could be wrong, but I believe in Edgar's example, the
redirect would always execute (since it sits outside the action).
Also, depending on how many protected url matchers you have, you can also
delegate all work to a resource where you could put all your authentication
and redirect logic (so you don't have to have it in each matcher). So you
could do something like this:
map:match pattern=some protected url
map:call resource=authenticatedAccess
map:parameter name=someIDForThisPipe
value=foo/
... any other params you might need to process this
pipe ...
/map:call
/map:match
map:match pattern=some other protected url
map:call resource=authenticatedAccess
map:parameter name=someIDForThisPipe
value=bar/
... any other params you might need to process this
pipe ...
/map:call
/map:match
And the resource might look like:
map:resource name=authenticatedAccess
map:act type=my-authenticator
map:select type=parameter
map:parameter
name=parameter-selector-test value={authStatus}/
map:when test=success
... stuff to process pipeline based
on params
/map:when
map:otherwise
map:redirect-to
uri=loginpage.html/
/map:otherwise
/map:select
/map:act
/map:resource
Anyway, hope that helps!

Hi Edgar,
I may be misunderstanding how actions work, but at least for how we've used
them in our project, anything after an action always executes, regardless of
whether the action returns a null Map or not. If an action returns a null
Map, it skips the steps inside the act tag, but it will continue executing
the steps after the act tag. If this isn't always the case, please let me
know. I'll be the first to admit that my understanding of Cocoon is far
from perfect! =)

But the last redirect is to a page that ask you to try again... when the

(that between the map:act is).

I'm trying to implement a homegrown authentication scheme. One of our
types of users will be authenticated by coming into the system with
appropriate credentials as request parameters in the URL (we will e-mail
them their unique URL). This is to avoid generating a large number of user
ids and requiring all these users to remember credentials for a system they
will likely use once or twice a year. None of the existing server-level
authentication schemes would seem to support this.
Once the user has logged in by providing the correct credentials, I
planned to store their identity and the fact that they have been
authenticated in their session.
So, each time a request is made to a protected page, I need to first check

Why do you have to redirect in an action? I would not suggest it. Redirect instead in the sitemap based on the results of the Action. I've always used the redirect method of the Redirector class. I'm assuming that redirect uses a local, relative path (for internal links) and globalRedirect uses a global path (for external links), but I haven't tested this and can't be sure. I also assume that sessionmode dictates whether or not to pass the session cookie on (there is a similar attribute in the sitemap redirect-to), but again I'm not sure and haven't tested. there have been times where I have wanted to redirect to the referer from an action, so that the action simply changes the state of something on the website (for instance, a log-in). I suppose I could pass the referer's address to the sitemap.. I'd be interested in hearing reasons of keeping the redirect in the sitemap, other than the fact that any changes to java code mean recompiling/restarting.. but changes to the sitemap also require recompiling and restarting tomcat, which seem to take longer for me (as the sitemap can no longer be loaded from cache). Changes to the sitemap don't require recompiling and restarting tomcat. If you need to do it, there is something plainly wrong with your Cocoon; I can't imagine how you managed to keep using cocoon given this :-O Anyway, the main reason is architectural. Cocoon was made with a sitemap because this makes the flow control and the component declaration in a central place; the whole site is much easier to administer and the components are easier to reuse.

What is the proper way to redirect in an Action?
I presume we are supposed to use the Redirector object, since nothing else
seems able. I've looked at the Redirector interface, but the API docs have
zero explanation (g!) of the methods. If this is the right object,
then:
1) what is the difference between redirect() and globalRedirect() and which
one should I use?
2) what is the meaning of the boolean sessionmode parameter?
I've searched the list archives and looked through the source and am none
the wiser.
Thanks,
Christopher

Onderwerp: Re: how do I redirect in an Action?
I'm trying to implement a homegrown authentication scheme. One of our
types of users will be authenticated by coming into the system with
appropriate credentials as request parameters in the URL (we will e-mail
them their unique URL). This is to avoid generating a large number of user
ids and requiring all these users to remember credentials for a system they
will likely use once or twice a year. None of the existing server-level
authentication schemes would seem to support this.
Once the user has logged in by providing the correct credentials, I
planned to store their identity and the fact that they have been
authenticated in their session.
So, each time a request is made to a protected page, I need to first check
the session to see if the user is already authenticated. If not, I need to
check the request parameters, if available, against the database. If both
of these fail, I need to redirect the user to a polite login failure page
(at some point we will have users that use a traditional login mechanism,
at which point we'll probably redirect to a login form).
I read the Action docs and searched through the mail archives, and I
thought I could do something like this:
map:act type=my-authenticator
map:match pattern=some protected url
...
/map:match
map:match pattern=some other protected url
...
/map:match
/map:act
As I understood it, if the authentication fails, I would redirect to my
failure page in the Action and return null to prevent anything inside the
map:act element from running. If the authentication succeeds, I return
an empty Map and the stuff inside the map:act element will run as usual.
Now that I'm saying all that it doesn't sound very likely, but I swear I
got it all from the docs.
Any suggestions?

What is the proper way to redirect in an Action?
Why do you have to redirect in an action?
I would not suggest it.
Redirect instead in the sitemap based on the results of the Action.

RE: how do I redirect in an Action?
Thanks for all the suggestions. I'm pretty confused at this point, as I
haven't used map:resource or map:select previously, so I need to spend
some time understanding the code you've offered. One thing in particular I
don't see is where I should put my normal generate, transform, and
serialize steps for the protected URL. Do they just go after the call to
the resource?
-Christopher
Hi Christopher and Edgar,
Couple things. I could be wrong, but I believe in Edgar's example, the
redirect would always execute (since it sits outside the action).
Also, depending on how many protected url matchers you have, you can also
delegate all work to a resource where you could put all your authentication
and redirect logic (so you don't have to have it in each matcher). So you
could do something like this:
map:match pattern=some protected url
map:call resource=authenticatedAccess
map:parameter name=someIDForThisPipe
value=foo/
... any other params you might need to process this
pipe ...
/map:call
/map:match
map:match pattern=some other protected url
map:call resource=authenticatedAccess
map:parameter name=someIDForThisPipe
value=bar/
... any other params you might need to process this
pipe ...
/map:call
/map:match
And the resource might look like:
map:resource name=authenticatedAccess
map:act type=my-authenticator
map:select type=parameter
map:parameter
name=parameter-selector-test value={authStatus}/
map:when test=success
... stuff to process pipeline based

/map:when

RE: how do I redirect in an Action?
Hi Edgar,
I may be misunderstanding how actions work, but at least for how we've used
them in our project, anything after an action always executes, regardless of
whether the action returns a null Map or not. If an action returns a null
Map, it skips the steps inside the act tag, but it will continue executing
the steps after the act tag. If this isn't always the case, please let me
know. I'll be the first to admit that my understanding of Cocoon is far
from perfect! =)

Harry,
I have to look in to you example later.
But the last redirect is to a page that ask you to try again... when the
action doesn't fail(the password is right) that redirect is not executed
(that between the map:act is).

Chris, if I do a redirect in an Action, does that effectively terminate the pipeline also?

I have never used the redirector object but it should do exactly that. Using the redirector object and redirecting on sitemap level should be equivalent. Also, is my understanding correct that if I create an Action that merely returns a new Map, this is essentially a no-action and will leave the pipeline unaffected? If a map is returned, the tags nested within the action are included in the pipeline. If no map (null) is returned, they are not included. This obviously does not prevent you from using side effects of your action. A database action could still modify data. BTW it is not required to nest anything inside an action. Hence, if nothing is nested, it doesn't matter whether your action returns a map or not.

RE: how do I redirect in an Action?
Hi Chris, Thanks for the clarification on pipeline termination! I'd never actually tried that since I assumed pipelines that used actions followed the same rules as normal pipelines (it's a sitemap compilation error if a normal pipeline has anything after the serialize tag).

C2: how do I redirect in an Action?
What is the proper way to redirect in an Action? I presume we are supposed to use the Redirector object, since nothing else seems able. I've looked at the Redirector interface, but the API docs have zero explanation (g!) of the methods. If this is the right object, then: 1) what is the difference between redirect() and globalRedirect() and which one should I use? 2) what is the meaning of the boolean sessionmode parameter? I've searched the list archives and looked through the source and am none the wiser.

Re: how do I redirect in an Action?
I've always used the redirect method of the Redirector class. I'm assuming that redirect uses a local, relative path (for internal links) and globalRedirect uses a global path (for external links), but I haven't tested this and can't be sure. I also assume that sessionmode dictates whether or not to pass the session cookie on (there is a similar attribute in the sitemap redirect-to), but again I'm not sure and haven't tested. there have been times where I have wanted to redirect to the referer from an action, so that the action simply changes the state of something on the website (for instance, a log-in). I suppose I could pass the referer's address to the sitemap.. I'd be interested in hearing reasons of keeping the redirect in the sitemap, other than the fact that any changes to java code mean recompiling/restarting.. but changes to the sitemap also require recompiling and restarting tomcat, which seem to take longer for me (as the sitemap can no longer be loaded from cache).
