Hi Chan Mei,
yes you can find it in the samples of Cocoon.
See an example at
http://cocoon.zones.apache.org/demos/release/samples/blocks/poi/welcome
Cocoon uses POI for this.

Re: Failed to run webapp
Gustavo, This error was reported before, see http://article.gmane.org/gmane.text.xml.cocoon.devel/73632 . It happens because cocoon.xconf includes other xml files and the xml parser barfs when it encounters a doctype. I had the same problem running with Java 6, but not with Java 5. The exact cause probably has to do with different (default versions of) xml parsers in the different jdks, but I haven't had time to look at it. For now the work-around seems to delete the doctype definition ![DOCTYPE ... ] from both cocoon.roles and sitemap-language.xml (and possibly other configuration files) Rogier On 6/23/07, Gustavo N.

Filesource questions
Hi, I think org.apache.excalibur.source.impl.FileSource is acting strange when handling temp files: - instead of using File.createTempFile(), it creates a temp file like this: // Create a temp file. It will replace the right one when writing terminates, // and serve as a lock to prevent concurrent writes. File tmpFile = new File(getFile().getPath() + .tmp); - furthermore, presumably because of the lock function mentioned in the comment above, it checks for an existing temp file, and throws a concurrent modification exception when it exists. The problem I'm having is that sometimes a .tmp file won't be removed after use. The next time it tries to create a file by the same name, FileSource will throw a concurrent modification exception, and refuses to write. Of course, at that point there is no other process writing the file. There is one other thread[1] where this behaviour is mentioned - when Gianugo was working on flow/webdav - it doesn't seem to have been resolved however . Finally - as an aside - is it really necessary to have Excalibur provide FileSource and factory? A quick browse through cocoon.xconf shows that there are only a few ( albeit very essential ) components that live in excalibur. From my point of view it hinders the transparency of Cocoon - I can't see straight away what filesource does and where it goes wrong. Imho it would be better to have Impl's in cocoon packages, even if the interface lives somewhere else. WDYT? Rogier [1] http://marc.theaimsgroup.com/?l=xml-cocoon-devm=105966223522106w=2

Re: Copying files with a transformer?
Hoi Geert, Copying as a side effect of a transformation is somewhat of an antipattern - iirc. OK, now that i'm reading more closely I see what you want - use the xml in the pipeline as a kind of script that does the copying. I don't think there's a transformer like that yet. Maybe you could even make an AntTransformer, so you can reuse Ant's copy/move/zip/etc. functionality. Of course you're still in the side effect transformation trap. Another way would be calling helper classes from flowscript. Again you can use Ant classes: I did something similar with an array of files returned by the Ant DirectoryScanner, which gives you a lot of filtering and wildcards-operations for free. Groet Rogier Geert Josten wrote: Hi all, I'm new to this list, so forgive me if I'm blunt or off-topic.. On the Cocoon users mailing list, there were some questions about copying files. We came up with solutions like using the copy-source actor, flowscript or perform an include and write it again using sourcewritingtransformer. I personally like the transformer alternative, sounds more dynamic to me than the others. But including and serializing requires generating SAX out of the source and streaming it again. One might be able to do this even with binary files, but wouldn't it be nicer to for instance allow the sourcewritingtransformer take a 'src' feature? (as an alternative to the 'fragment' feature, or as an attribute of the fragment element?) Or have I simply overlooked a transformer that already provide this kind of functionality? Cheers, Geert

Cocoon based CMS
Hi, I just noticed that on the page http://www.mail-archive.com/users@cocoon.apache.org/msg23042.html the topmost Google ad says: Apache Cocoon-Based CMS XML content management system based on Apache Cocoon.

Quote Leszek Gawron [EMAIL PROTECTED]: Jorg Heymans wrote: Have you tried using Castor ? You mean replace the XMLBeans implementation with a castor based one? I don't see how this would solve my initial problem though, is there some castor specific functionality you had in mind? (i've never used Castor) Me too but my understanding is that Castor is able to map any bean to XML (based on a mapping configuration file). There's a castor transformer in the scratchpad. What it does is either marshalling a bean to an xml-fragment in your pipeline, or unmarshalling by taking sax-events and creating a bean from that. I only needed the unmarshalling part, and it was really buggy, but I suspect that's because only the marshalling was tested. Don't know for sure though, it's scratchpad after all ;). The mapping file is reasonably simple, and it should also work without a mapping, especially for marshalling. I don't know zip about XMLBeans. From the name I would assume it is possible to use the custom transformer approach the way CastorTransformer does. Rogier

Invalid content length, revisited
Guys, On 18/5 Joerg asked a question about invalid content length errors[1] due to readers. There is also a bug that is somewhat related[2], but it seems to be WONTFIX. I have the following case : generatorreader | | validator .. dtd | serializer In this case the reader sets the content-length, and the serializer doesn't. So if the length of the serializer's output is greater than that of the dtd, output is incomplete. Althoug a quick fix is not to get the dtd through a reader, I'm sure there are cases where that isn't a solution. I didn't post this as a bug, yet, because I am not sure whether this is just unintended use of the reader. Also, I can't quite get my mind around what's the best way to solve this. Joerg suggested in his original mail[1] to build some awareness in to the reader to see if it is called as a cocoon-source or not. Another possible solution would be setting content-length from all serializers, although Carsten suggests in the closing of the bug that content-length can not be set repeatedly. OTOH I tried to reproduce this behaviour by getting an XSL through a reader, like so: map:match pattern=read.xsl map:read src=tiny.xsl/ /map:match map:match pattern=readtest.xml map:generate src=sitemap.xmap/ map:transform type=xslt src=cocoon:/read.xsl/ map:serialize type=xml/ /map:match But apparently the xsl-transformer doesn't like that.

Re: rich clients in Flash with Cocoon?
Forgive me for promoting the non-free solution, but I've always thought that Macromedia's own flex[1] is a very nice solution, being java-based and all.

I think the technology holds a lot of promise, and could be particulaly useful in things like Forrest, but we will need some extra components before they will be readily used in Cocoon, particularly a TopicMapMergeTransformer, and some kind of TM-oriented templating transformer for rendering. I haven't had a chance yet to deal with it, but it's on my list of things to do :-) By the way, did you realise that the tm4j project actually already includes some Cocoon components? No, I didn't - thanks for the info. Forgive me if the following is a little hazy ;) I've seen some sites useing topicmaps as site structure - and I recall reading about some basic topicmap implementation for websites. But I was thinking more of topicmaps as a general repository of topics and relations, queryable by sitemap components - hence the TopicMapTransformer. Maybe it would even be possible to create on-the-fly queries. Something like, when looking at a webpage about a book, you can say: I want to see webpage on other books in the same genre but not by the same author and published after 2002. TopicMapTransformer then queries topic map and shows results. Some may say: if you want to express relations why not use a relational database, but I like the abstraction (tm4j runs on a hibernate backend, too), plus it's xml.

Related Documents, MapTransformer and Topic Maps
Hi all, We have a client who required a website with a related document function. This means that each document in a collection contains keywords, and when the document is displayed, it also shows a list of other documents that contain one or more of the same keywords. There are a lot of documents in this collection, and although they are stored in an XML database, I didn't really feel like querying them in real-time. I really wanted something lean and mean. So in XP fashion, I picked the simplest datatype to express relations, java.util.Map, and went from there. The keys in the map are the keywords from the document collection, the values it returns are URLs pointing to the documents that contain this keyword. So I ended up with two components: - MapManager - initializes one or more maps from a ( cocoon ) xml-source, which is constructed according to a specific DTD. The datatype stored in the map can currently be one of String, Set or SortedSet ( in case results are sorted by relevance ). - MapTransformer - looks for key elements in a specific namespace, and transforms the value(s) returned by the map into the key element. The names are a little confusing because the use of 'map' in cocoon usually refers to the sitemap, but a change is just a simple refactoring away. If anyone is interested in this functionality I'd be happy to donate it. If you think this is not the right way, or there are other ways to do this in Cocoon, let me know. --- [RT] I tried to make this mapping very generic. It could be keyword related document, keyword explanation, document related document, or url metadata. A first extension would be keys with wildcards or RE's although that would force me to loose the map model. Googleing xml and relations quickly brought me another subject that I haven't seen discussed much here - XML topic maps. On of the big advantages of topic maps over my simple mapping is the amount of semantics that topic maps allow. Topic maps allow one thing to be related to another, and also describe what the one thing is, what the other thing is, and what kind of relation they have. So the next step would be to implement a topic map transformer. There is a apache-license topic map project at http://sourceforge.net/projects/tm4j. I'm definitely going to look into it myself, but need to do some reading first, and I would like to discuss it. By the way, if you don't like topic maps, I would like to know too - I wasn't able to find any criticism on the matter (googleing 'why topic maps are bad' or 'topic maps suck' didn't help) With kind regards / Met vriendelijke groeten, Rogier Peters - Content Management Department Hippo Webworks Rogier(at)hippo(dot)nl / www.hippo.nl
