Courses on Cocoon 2.2 in Europe
Hi all! We're just getting started on a free software project that will use Semantic Web technologies. We have opted to use Cocoon 2.2 for this project. However, we are all inexperienced with Cocoon, that is, I worked a bit with Cocoon back in 2002 before I went on to work with AxKit for a few years. We are very interested in a course on Cocoon 2.2 if someone could give one somewhere in Europe in near future. Are there any courses given nowadays?

We're doing some work in that area, but the answer to that question depends on what you want to achieve. Do you want to take RDF/XML-data, parse it, then do a SPARQL SELECT query on it to get the SPARQL Result set, or a DESCRIBE or CONSTRUCT query to get more RDF/XML, or something completely different?

Magnus is my colleague, sitting just beside me, and I'm not sure, but I think
he did just that. The funny thing is that it works well on my Linux box, but
not on his Windows box. I think he did investigate the standard encoding too,
are there other possible points of failure that might be windows-specific?

Getting the request query parameters in the XML
All,
I need to access the query parameters from a GET request in my XSLT, and I
have thought of several ways to do this, but all seems cumbersome, so I'm
supposing I've lost something trivial.
What would have been neat is something ol' AxKit's QueryParam could be done:
http://search.cpan.org/~nachbaur/AxKit-XSP-QueryParam-0.02/lib/AxKit/XSP/QueryParam.pm#
i.e., just say in the JX that I want all query parameters, and there they are.
If there is no way to do that, I could do something like it in a controller we
allready have. We allready do stuff like
bizData.put("result-list", queryResult);
res.sendPage("xml/sparql-result", bizData);
and it would be OK if I could just dump the query parameters here, but it
seems there is no other way than build the XML manually by looping over the
queryparameters, which again seems unnecessarily cumbersome.
What am I missing here?
Kind regards
Kjetil Kjernsmo

Ah, thanks, I think that's the nearest to what I was looking for, even though
Luca's solution was shorter to write.
I modified it to
${v}
which seems to do what I want.

Setting a pipeline for true XHTML
All, I much prefer to work with XHTML, and do so sending application/xhtml+xml, but when sending to browsers, certain clients fail. So, I should send proper XHTML to clients that supports it, and dumb it down to HTML and use text/html to clients that don't. Cocoon seems ideally suited to do this. The dumbing down is probably easy enough, AFAICS, this stylesheet will do the trick: http://www.stylusstudio.com/xsllist/24/post10360.html Now, I just need to append this to the pipeline, but only for the clients that doesn't support application/xhtml+xml. So, my question is, how do I do that? I tried to google for this, since it is a pain that almost everybody has, but it was hard to come up with proper keywords, so I didn't find anything...

Yup, I know hixie both personally and technically (we worked together at Opera), and I think all his arguments are invalid, and frameworks like Cocoon prove it. In modern web frameworks, it is trivial to serialize to different formats, and while there are subtle differences, they are trivially resolved with a few lines of XSLT and a simple pipeline. I know that Cocoon can do it too, but not quite how yet. :-) Hixie was never exposed to a proper framework, so he is of the faulty impression that these things are hard, thus the statement "Steps 1 to 5 have been seen by every single person I have spoken to who has switched to using the XHTML MIME type."

[2.2] Configuring LocaleAction
Hi there! I need to get to the user's language, partly based on a request parameter, partly the Accept-Languages HTTP header. LocaleAction is not documented in 2.2, but looking into the code, it seems like it can do this. Correct? Now, I want to stuff this into a parameter interface-language that I have allready coded in many places. I have e.g. this: But since all pages are localised, this parameter should be sent to everything in the sitemap. Is there an easy way to do this, so that I can set it in just one place? if not, do I need to put into every map:match I have? If so, would I need to code the above example like this: ? BTW, there are lots of XML errors in the 2.1 docs for this.

Re: [2.2] Configuring LocaleAction
All, My longest example for LocaleAction worked. Also, it seems like LocaleAction works well, but I don't quite understand all aspects of configuring it. I have it working for the situation where I call a function, but not where I call and XSLT transform. The simplest possible would be something like: I've tried moving around where the map:act element is, but it always crashes with a java.lang.UnsupportedOperationException. How is this supposed to be done?

Just to clarify this, I intend to use the HTTP Accept header. Browsers that reliably do this send application/xhtml+xml in the Accept header. Does this imply the use of the RegexpHeaderSelector or is there a better suited selector?

LocaleAction to preserve settings
All, I'm struggling with LocaleAction. I've set it up, and so far, using the default and Accept-Languages through use-locale works well. Now, I'd like to provide the user with a simple way (i.e. simpler than setting browser settings, people don't tend to use it, unfortunately). The application is RESTful, so I was hoping to keep it that way and avoid cookies. Thus, store-in-request looked like the right thing. I was hoping using this was as simple as adding ?locale=no to some URIs to have it set, and then LocaleAction would take over and ensure it would be appended to all internal links or the page, but it was apparently not the intention. Am I overlooking something obvious here, is there a way to do this easily? So, I tried setting true, thus abandoning the REST design goal. A session seems to be created now, I get a session cookie, even though I didn't really ask for that. Also, I see that even though I manage to get one request to see the new locale I give it, the next request does not retain this information. So, apparently, the session cookie set has no influence on the locale set by the request. My code correctly uses the locale, so the problem here is only that the locale is not retained across requests. How can I use Cocoon to do this?

Get the SVN revision number into the sitemap on 2.2
All, We're in a system test phase, and it would be useful for the testers to know which Subversion revision they are testing. Thus, I'd like to get this into the XSLT as a variable, which is easy if the sitemap can get hold of it somehow. So, I figured maven could get the revision number somehow at build time, but I couldn't find any concrete way of doing it. Is there a way?

Ah, great, cool! But how do I communicate the ${buildNumber} to the sitemap,
then?

Hi all, I've been trying to figure out how to get the URL of the originating client, i.e. the URL that the end user has in his address bar when he gets the response. I want to have access to this URL in my XSLT, preferably through a param variable. I've been experimenting a bit, but I cannot find a single simple solution to this problem, I usually end up with the URL of the stylesheet, or a variation thereof, or some more speculative concatenation of things like hostname, port, and so on, which is fragile against changing conditions. Is there a simple way to do this?

Rewriting EncodeURLTransformer to encode the locale parameter
Hi all, I've been struggling a few days with adding a locale parameter to the local URLs in pages I serve. It should be really simple, just add the parameter to all hrefs that points to a resource within the site. I've tried to do it with XSLT through various approaches, but all unsuccessful, it is either very fragile string matching, too fragile to be useful, or too complicated, in that it breaks my architecture. However, I see that the EncodeURLTransformer is doing almost the same thing. It add a session-id parameter if it is doesn't exist, mine should add a locale parameter if it doesn't exist. EncodeURLTransformer are 400 lines of code though, some of which I don't understand, so I'm hesitant to hack based on it. For one thing, I don't understand if it restricts the URL rewriting to URLs that point to resources on the same site, and if so, how it does it. So, I was wondering if someone has time to hold my hand while doing this? Also, this might be useful for the Cocoon project, as I think it is really important for LocaleAction to be useful, it's request feature is really quite useless without such a transformer. Please?

Oh, OK. Actually, I looked at that but realised that I didn't quite understand what it did, I thought it more did something like mod_rewrite, i.e. rewrite incoming URLs. > That said, the LinkRewriterTransformer looks up the InputModule based > on the url scheme, so you would have to use a custom scheme (e.g. > locale:) for all the 'schemeless' (e.g. "/path/to/some/page.html") > links you wanted rewritten. H, OK. I'll look into it, but I think I found an XSLT way that sort of works too.

Redirecting with 303
Hi all! I want to do a 303 redirect, to satisfy the httpRange-14 TAG finding, with its popular form http://www.w3.org/TR/cooluris/#r303gendocument I was hoping something like this might work: where the URI needs to be the whole thing, including the hostname and all. I guess that the latter can be fixed some way by concatenating some parameters. And I hope the 303 would be fixed by the but it doesn't, it does a 302. Is there a simple way to achieve this? If no simple way, what would the difficult way be?

The semantics of 302 is very different, with 302, both URIs deal with the same resource, it is just that they are temporarily the same. What we are doing here is dealing with URIs for things that are not network-retrievable, such as people. In this context, a 303 means "you cannot retrieve a person through the network, but here is a description of the person". This is a key concept in the Semantic Web. So, what would the simplest way to do this with Cocoon be?

Yeah, the warn there is about log4j, which was the source of most of the problems. A logging infrastructure should never require configuration to get basic debugging information, that's the whole idea of logging, but this one does. You have to initialise it properly, but I never found any really good documentation how you would do it. One of the things that we did was to move the config around, responding to conflicting advices from different parties, but now it half-works, and I've placed it in src/main/webapp/WEB-INF/log4j.xml I cannot tell for sure, but I think log4j was responsible for the problems we had. It still throws an exception so that I have to restart tomcat every time I deploy, but I can live with that. I guess this isn't encouraging nor very helpful, but since you haven't any other answers that did the trick, that's my wild guess, have a log4j config that you move around in likely and unlikely locations.

Tomcat loops indefinitely
Hi all! I'm struggling with a really weird problem. I have a Cocoon 2.2 application that runs on Tomcat 5.5.25-5ubuntu1 and Java 1.5.0. My (semi-)production system, my test system and my development system are Ubuntu 8.04 boxes, and they differ very little, with the exception that the production environment is a Vmware slice, the others are not. The application runs fine on the development and test systems, but it is not at all working on the production box. What's happening is that I deploy the war, restart the server. I then GET a URL on the system, apparently, any URL will do. The application starts doing its thing. In my log, I see messages like http-8180-Processor230 DEBUG impl.DefaultSparqlDispatcher - SPARQLdispatcher connected to Joseki. http-8180-Processor229 DEBUG impl.DefaultSparqlDispatcher - SPARQLdispatcher connected to Joseki. http-8180-Processor228 DEBUG impl.DefaultSparqlDispatcher - SPARQLdispatcher connected to Joseki. which my application emits. The problem is that the application has apparently gone into a loop, as this appears to be different threads. Eventually, it runs out of threads, and comes to a halt: Sep 4, 2008 3:36:52 PM org.apache.tomcat.util.threads.ThreadPool logFull SEVERE: All threads (250) are currently busy, waiting. Increase maxThreads (250) or check the servlet status I've tried to debug this in several ways: My gut reaction was that the client was actually throwing tons of requests at it. I falsified this by telnet 127.0.0.1 8180 GET http://127.0.0.1:8180/detektor/ (/detektor/ is the application context). This reproduced the problem and telnet would not follow a redirect. So, it is entirely a server side problem. Then, I installed the "standard" sample.war application, and that told me "hello world", so I guess Tomcat is not entirely to blame either, though I suspect of somewhat foul play for some reason... :-) I've rebuilt and deleted the application many times, stopped and restarted the server many times, generally performed the rituals that needs doing now and then. I've also copied over the war that works on my development box (I tend to package on the production box from a SVN tag). So, it can't be the client. It can't be just Tomcat, it can't be just my application... It doesn't sound very likely that it is VMware. I suspect that I have made some deity rather upset since I'm actually a Perl guy ;-) Does anybody have any idea where I can start?

Send status code with error handler
Hi all! I have a very simple exception handler in my sitemap: so that the user will never see a stacktrace. We have a servlet service listening in a different sitemap, the setup looks like this: This works great, except for one thing: I still want to send the 500 HTTP code, even though the user gets a pretty page.

Sending different responses based on some conditions
Hi all,
I have a StatelessAppleController which does some simple checking on the data
it receives. In most cases, it should sendPage, but there are a few rare
situations where it should redirect or return a 502 HTTP code.
This part of the code looks like this:
if ("explain".equalsIgnoreCase(operation) ||
req.getCocoonRequest().getParameters().size() == 0) {
// We only need to retrieve the explain record, which is best done
by a redirect to the server
res.redirectTo(query);
}
DOMParser parser = new DOMParser();
try {
parser.parse(query);
} catch (Exception e) {
//logger.fatal("SRUClient received an invalid response from the
server.");
res.sendStatus(502);
e.printStackTrace();
}
but I get
java.lang.IllegalStateException: It's not possible to call redirectTo() and
sendStatus() at the same response object.
Surely, this must be possible to achieve, I guess I just did it the wrong way.
How can I do this?
Kind regards
Kjetil Kjernsmo

{language} sitemap parameters
All,
I've been using LocaleAction for a while, but it hasn't worked very well, and
now I needed to resolve some bugs in the application in the language
handling. Basically, all I want to do is turn off the feature that looks in
the Accept-Language header (since it doesn't do a full language negotiation
process as specified in HTTP) and set the default locale to Norwegian
language. This should be trivially configureable, but I have never gotten it
working, so eventually, I had to realise that I simply don't understand how
LocaleAction works.
So, I started to read the code, and I forked it to add more debug information
and to hardcode our desired locale whenever possible. What I found was that
the configuration method of the code does run OK and all the correct
parameters are set.
In my sitemap, which can be found at
https://submarine.computas.com/sublima/trunk/blocks/sublima-app/src/main/resources/COB-INF/sitemap.xmap
I have sections like
So, I set the interface-language parameter to {language}. So the critical
issue here is how {language} is set. LocaleAction seems to be the right way
to do this.
With my slightly modified LocaleAction this is what I see in my logs when it
is enabled:
http-8180-Processor25 DEBUG action.LocaleAction - will set values in request
http-8180-Processor25 DEBUG action.LocaleAction - won't create session
http-8180-Processor25 DEBUG action.LocaleAction - won't set values in session
http-8180-Processor25 DEBUG action.LocaleAction - won't set values in cookies
http-8180-Processor25 DEBUG action.LocaleAction - Locale attribute name is
locale
http-8180-Processor25 DEBUG action.LocaleAction - won't use request locale
http-8180-Processor25 DEBUG action.LocaleAction - default locale no_NO
http-8180-Processor25 TRACE controller.SearchController - SearchController:
Language from sitemap is en
So, everything looks fine up to the final line. The final line stems from the
controller, which uses the interface-language parameter. I have confirmed
that this language is set to the Accept-Languages header, regardless of the
default locale and regardless of that I have explicitly disabled it.
Furthermore, the interesting thing is what is not in the logs: There's nothing
from the act method, so it appears that act is actually never run.
However, if I send a locale query parameter, things look much better, e.g. if
I send ?locale=sv, I get:
http-8180-Processor25 DEBUG action.LocaleAction - won't use request locale
http-8180-Processor25 DEBUG action.LocaleAction - default locale no_NO
http-8180-Processor25 TRACE controller.SearchController - SearchController:
Language from sitemap is sv
i.e. it works as intended.
So, the problem is only that the Accept-Languages header override the default
even if disabled, it works nicely if a query parameter is used.
Now, I did another interesting exercise: I commented out the LocaleAction
matcher.
The log now confirms that LocaleAction is not run at all. To my great
surprise, it has exactly the same behaviour as before. I.e. query params
work, but the Accept-Languages header is still what is used.
I haven't seen this behaviour documented anywhere. I thought that LocaleAction
was required to even use the {languages} variable, but now it appears that
there is something in Cocoon core that does this.
So, is there any way I can disable Accept-Languages and hard-code a default
that is used whenever a locale query parameter is not given?
Kind regards
Kjetil Kjernsmo
