RE: how do I redirect in an Action?
This is how it works in my project.
Christian Haul says the same I guess:
Another misconception in this thread seems to be that the tags after
the action will always be processed. That is only true if it was
determined that they are part of the actual pipeline.

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).

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!
Harry

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
AW: Question: what is {session-id} ? in a sitemap.xmap ?
Hi John,
unfortunately, it is not enough to set 'fred' as a session attribute, who
would have to set
it as a sitemap parameter just as Artur said.
You can do this inside an action (actions return a java.util.Map and you can
use the keys
stored in it as sitemap parameters. I don't know if it is there in 2.0.1 but
in 2.0.2 you can look
in the docs under User Guide / Concepts / Actions and there at
'Communication between Sitemap
and Action'.
As Artur also pointed out you can call a resource with some parameters which
you can then use as
sitemap parameters inside the map:resource tag.

Thanks. It is pretty clear that {name} is a variable. My question

The example I was looking at used {session-id} which is intuitively

name=session-id/. Is my inference correct? Does it therefore follow

Is the definition of {name} documented anywhere ? Is there any way of
enumerating defined names ?
From what I know, basically {name} is a representation of
a sitemap parameter which are used by sitemap components.
For example, if your pipeline wants to call another (resource)
pipeline you with a target parameter you would do it this way
map:call resource=simple-page
map:parameter name=target value=some/path/to/something/
/map:call
now in your simple-page pipline you can access that target
paramter with {target} so you can have:
map:resource name=simple-page
map:generate type=file src={target}.xml/
map:transform src=stylesheets/page/simple-page2html.xsl
map:parameter name=view-source value={target}.xml/
/map:transform
map:serialize/
/map:resource
Also, if you implement actions the return of the act() method
is a map that will be added to the session paramters.
In your action of you do
sitemapParam.put(session-id, getSessionID()); then
in your pipeline you can do
map:match pattern=something
map:act type=my-action
map:generate src=something/{session-id}/
...
/map:act
/map:match

The whole process is made in two steps: 1) determine what the pipeline actually contains by evaluating actions, matchers, selectors, call and redirect tags. A pipeline is terminated when a serializer is found. For the sake of brevity I consider a reader here to be a (generator + serializer). 2) Use the components (readers, generators, transformers, serializers) determined in step 1. Note that in this step no actions, matchers, or selectors are used. IOW if a serializer is nested inside a map:act tag, it effectively terminates the pipeline and tags beneath the map:act will not be considered. It works just like it was mentioned with redirects or calls.

Since these vars depend on the components that set them, they are
documented in the (java)docs for these components (e.g. matchers,
actions).
If you have a close look at your log files (sitemap.log), you will
discover all present vars with their names and values after every step
that as potential effect on them. E.g.
Current Sitemap Parameters:
PARAM: '1' VALUE: 'apps'
PARAM: '0' VALUE: 'sample-apps'
You have two vars named 1 and 2 available at this stage of the
pipeline.
Chris.

RE: XSP Expression within XSL:for-each loop
Finally I found a solution, and it has nothing to do with Cocoon. The XSL
fragment in my question is part of an XSL template, and is preceded by two
statements loading two different xml files as a documents and querying for a
value in them. Later, another template uses position() to mark the
positions of gvs-list elements returned by the java method call and created
the HTML for select list. I could make it work by using position() div
number('2') instead of position() to do this indexing. If I load another
document prior to uti-include-expr, I will have to change it to
position() div number('3') to make it work, and so on.
But I don't understand -why- this works. Can some one enlighten me?

Subject: XSP Expression within XSL:for-each loop
Hi Gurus,
I have a piece of code with the following for-each loop:
xsl:for-each select=document('actions.xml')/actions/action
xsl:variable name=target-class
xsl:value-of select=@class/
/xsl:variable
util:include-expr
util:expr
xsp:expr
xsl:value-of select=$target-class/.getAll()
/xsp:expr
/util:expr
/util:include-expr
/xsl:for-each
The intention is to determine the class name at run time and get all
persistent objects of that class from the database.
The reality is that the util:include-expr/util:include-expr part is
using only the very first $target-class value, even though the $target-class
value is different for different action elements. Of course, if I just print
out the value of the variable target-class right before entering the
util:include-expr/util:include-expr, it prints out all the different
values, as it should.
When I look into the generated class, here's what I find (assuming target
class is Singer, and excluding fully qualified class names):
1. {
2. Parser newParser = null;
3. try {
4. newParser = (Parser) this.manager.lookup(Parser.ROLE);
5. InputSource __is = new InputSource(new
StringReader(String.valueOf(Singer.getAll(;
6. XSPUtil.include(__is, this.contentHandler, newParser);
7. } catch (Exception e) {
8. getLogger().error(Could not include page, e);
9. } finally {
10. if (newParser != null) {
11. this.manager.release((Component) newParser);
12. }
13. }
14. }
This code block is repeated for each value of $target-class, with the method
call Singer.getAll replaced with the correct value of $target-class - i.e.,
if $target-class = {Singer, Actor, Producer), the block above is repeated
thrice, with Singer.getAll(), Actor.getAll(), and Producer.getAll() as the
method calls in line 5.
That part is as it should be; but when I see the output, I actually see only
the results of Singer.getAll() appearing thrice! Is the finally clause
releasing the newParser in line 11 responsible for this?
How can I get this to work right? Am I missing something in the way I am
including the expression?
Thanks, and Best Regards,
Sreedhar

Fw: XML Schema Components Infoset Model in Java by IBM is available on Partnerworld for Developers
FYI, Very interesting reading for those of you who asked about XML Schema API before. I know a few people wanted to create XML instances from Schema. Validation might be also improved with this. - Original Message - From: Bob Schloss [EMAIL PROTECTED] To: [EMAIL PROTECTED]; [EMAIL PROTECTED] Sent: Friday, May 24, 2002 4:33 AM Subject: XML Schema Components Infoset Model in Java by IBM is available on Partnerworld for Developers There has been a lot of discussion (on various mailing lists) about the benefits of a standard API which would allow software that creates, examines or modify XML Schemas, written in Java, to do so in a way that represents the semantic XML schema components described in the W3C XML Schema specifications. In February, we shared with the W3C Schema and DOM working groups some thoughts about what such an API should try to do. You can see those 'requirements' described here: http://www.research.ibm.com/XML/schema/WD- XML-Schema-Infoset-API-Req.htm . I have been lucky to work with Ed Merks, part of the IBM Websphere Studio Application Developer (WSAD) development group, to define such an API and to produce a reference implementation. Although we have not yet completed every last function we have in mind to implement, nor have we done any performance tuning, this API has been used successfully in building several real XML and Web Services developer-time tools. We have tried to make a reasonable and straightforward Javadoc, and have been grateful to have Shane Curcuru, who has worked on the Apache Xalan team, give us some guidance on how to do this. We are aiming for an API which is very complete: not simply read-only, and able to handle any XML Schema, no matter how complex. We tried to use the terminology from the W3C's XML Schema specifications in naming our classes/interfaces, methods, and constants. We have now made this work, including source code, UML, example usage code and documentation, available publically for the wider community to examine and use. Donating a future version of this to some open source effort is possible, although I can't make a commitment on behalf of IBM at this time. Reaction and comments from the Apache community would strongly influence whether we do this. We encourage you to download our work. You can do so through IBM's Partnerworld for Developers web pages. https://www.developer.ibm.com/member/register/how2join.html - shows how you can get yourself an ID and password if you've never joined Partnerworld for Developers https://www.developer.ibm.com/websphere/member/workbench_beta_download.html - where you can find the XSD Feature, the name for the Schema Infoset Model (aka com.ibm.etools.xsd) Although I am posting this notice here, I recommend that all discussion about this, at least until the end of June, take place in a single venue. I recommend that questions and comments be posted to [EMAIL PROTECTED] . (The archive is: http://lists.w3.org/Archives/Public/xmlschema-dev/ .

Saxon and Cocoon
Hi, earlier I asked how I would use Saxon in Cocoon. It is very simple, delete Xalan and place Saxon in. Saxon 7 is really fast! I see the difference. My problem was that I didn't notice anything different, so I guessed I did something wrong. However I had a jar called j2ee.jar in my lib, it contained Xalan. If you also want to do this, the search the core.log for templatesHandler. If Saxon is there you did everything right - Please check that your question has not already been answered in the FAQ before posting. http://xml.apache.org/cocoon/faqs.html To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
refactored samples all '404'
Hi, I'ved deployed the cocoon.war (2.0.2), but all the links on the 'refactored samples' page (http://localhost/cocoon/samples/welcome) bring up a '404 not found.' The main page says it's a 'work in progress', but the '404' for every link is suprising. (i.e. I would have expected the 'easy' examples to work.)

XSP Namespace Problem

Re: AW: Question: what is {session-id} ? in a sitemap.xmap ?
Thanks. Some of this is starting to become clearer. Unfortunately, it seems that the only way to learn Cocoon is to read the source code. That isn't going to cut it for much longer. It would be nice if there were a list of all of the similar variable types and their purposes and how to set them and use them. Perl becomes understandable (well ... a bit) when the different types of name are explained. unfortunately, it is not enough to set 'fred' as a session attribute, who would have to set it as a sitemap parameter just as Artur said. You can do this inside an action (actions return a java.util.Map and you can use the keys stored in it as sitemap parameters. I don't know if it is there in 2.0.1 but in 2.0.2 you can look in the docs under User Guide / Concepts / Actions and there at 'Communication between Sitemap and Action'. As Artur also pointed out you can call a resource with some parameters which you can then use as sitemap parameters inside the map:resource tag. - Please check that your question has not already been answered in the FAQ before posting. http://xml.apache.org/cocoon/faqs.html To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
