Re: from Cforms to Wicket
All the cool people swear by caniuse.com [1] ;-) Another very new resource is the WebPlatform.org site [2] which is in alpha at the moment but is the first collaboration between all the major browser manufacturers to document the browser standards and collate bugs. So to answer Mika's question: HTML5 is already widely supported by browsers. Or to put it another way the HTML5 doctype was designed to be usable without breaking older browsers but also prevent them going into quirks mode. Scripts like modernizr [3], also enable very old browsers (even IE6!) to partially support some of the more desirable CSS3 functions. I don't know about you but 20% of my traffic is mobile based. Whatever forms you do generate it is looking more and more like you also need to support Responsive Web Design which adapts to the browser window size and device input capabilities. We are living in interesting times at the moment from a web perspective and for the past year people have been rushing to 'do responsive' by placing most of the logic client side and making extensive use of media queries. Some people are beginning to wake up to the fact that it might be better to do a little device detection server-side with a technique that Luke Wrobleski coined 'RESS' [4]. This is something for which I think Cocoon might be a good solution. One final thing you may find of interest is a side project of Wicket which I tinkered with a while ago called WicketWebBeans [5]. I have no idea if it is still being developed but essentially it dynamically creates web forms by directly interrogating java beans. You can tailor the behaviour according to your needs.

Notes on getting Cocoon 3.0.0-alpha-2 sample app running
Here are some notes I made while trying to get started with the Cocoon 3 alpha 2 sample apps running under Windows XP using Maven. Hopefully it might help others like me starting down the C3 road and serve as a record of the corrections needed to the current documentation ;-) The place to go for documentation on running the sample apps is the Cocoon 3 download page [1]. The simplest way to get the sample app up and runnning is to use Maven to do the heavy lifting. As the documentation mentions under the 'Maven 2 archetypes' heading you have to type the following line to create the sample block: - mvn org.apache.maven.plugins:maven-archetype-plugin:1.0-alpha-7:create -DarchetypeGroupId=org.apache.cocoon.archetype-sample -DarchetypeArtifactId=cocoon-archetype-sample -DarchetypeVersion=3.0.0-alpha-2 -DgroupId=com.mycompany -DartifactId=mysample Note: you have to place everything on one line before pasting it into a windows DOS box or else only the first line will get executed. This should proceed correctly and a new directory will appear called 'mysample' which you should change into for the next part. I tried typing 'mvn jetty:run' to execute the sample app but I kept getting a couple of Maven dependency errors: - com.sun.jersey:jersey-core:jar:1.0.3 com.sun.jersey:jersey-server:jar:1.0.3 Never having heard of Jersey[2] before (the new Restful API reference implementation and not the place or the item of clothing!) I looked it up and noticed the dependencies page[3] which led me to add the following to the pom.xml file just below the packaging tag: - repositories repository idmaven2-repository.dev.java.net/id nameJava.net Repository for Maven/name urlhttp://download.java.net/maven/2//url layoutdefault/layout /repository repository idmaven-repository.dev.java.net/id nameJava.net Maven 1 Repository (legacy)/name urlhttp://download.java.net/maven/1/url layoutlegacy/layout /repository /repositories After this I could successfully run the sample app... but only after looking in the correct URL ;-) The documentation[1] gives the wrong one. The Jetty server is set up to actually run at http://localhost: Hope this helps.

Re: cocoon.forms is undefined when using submit-on-change=true for Field Widget
Hi, I somehow got it working… not sure if changing the serializer from xhtml to html fixed it though. In my experience, yes. When using the XHTML serializer it seems that the script/ elements in the head are not all recognized as XML elements. Adding some newlines now and then helps fixing this issue. Just for interest you may find my updates to the HTMLSerializer document [1] useful in this regard. I think the script tag is treated differently between XHTML and HTML.

Re: Starting out with Cocoon 2.2
Hi David, I'm just about to embark on a new project... I'd like to use Cocoon 2.2 for this, but I'm concerned about the apparent lack of support for it. It is true that Cocoon has hit a low point at the moment and I'm sure many of us wonder if it will ever recover. Many of the original contributors have moved on to other things and officially version 2 (and 2.2) are in 'maintenance mode'. Version 3 is still being worked on but to be honest it looks so different that you will be starting again from scratch compared to version 2. It's a great shame as I really thought version 2.2 was beginning to gain traction. Can anyone suggest any resources that will help me get started with Cocoon 2.2? I would archive that book on version 2! It will be of little use to you when working with 2.2. Most of the useful documentation can be found here: - http://cocoon.zones.apache.org/dev-docs/2.2/1159_1_1.html But you should be aware that this is the 'published' version of the documentation. It may be the case that the 'unpublished' versions are more up to date. To get to them you can click on the link at the bottom of the page where it mentions 'Errors and Improvements'. This link will take you to the Daisy CMS which is what Cocoon members use to write and edit documentation before it gets published. Yes!... It is a horrible mess and I have commented about this before but was persuaded it was for the best. I'm concerned that interest in and support for Cocoon is dying out. Would I be better off choosing a completely different technology for my project? I would say think seriously before you commit another year or two of your life to learning it!

Re: AW: AW: [C2.2] Display Upload Progress
Hi Matthias, first, a big THANKS for helping me and at the same time sorry that i destroyed your sample webapp. No problem! what i didn't understand so far is: which instance decides which version of an artifact is the latest? why does maven try to download e.g. cocoon-core:2.2.1 when it's not available/released? If you look for the pom.xml file in the [Cocoon trunk folder]/parent folder you will see the dependency for cocoon-core listed as follows: - dependency groupIdorg.apache.cocoon/groupId artifactIdcocoon-core/artifactId version2.2.1-SNAPSHOT/version /dependency As all the other blocks refer to this parent pom file that's where the version number is set. The Cocoon developers could have put the version number in each block's local pom.xml file but in a large project like Cocoon it makes more sense to set the version number in one place only. Maven should only try to download an artifact from a remote repository if it can't find it in your machine's local repository. The reason for the 'mvn install -P allblocks' command is to ensure that all the Cocoon block artifacts get built and then intalled in your local repository. If you are running on windows this is usually located in C:\Documents and Settings\[user name]\.m2\repository\ If you see maven trying to download a cocoon artifact (as opposed to a plugin) from a remote repository it suggests something is wrong. I didn't see that when I built it from scratch though. Regards, David Legg - To unsubscribe, e-mail: users-unsubscr...@cocoon.apache.org For additional commands, e-mail: users-h...@cocoon.apache.org

The Cocoon developers could have put the version number in each block's local pom.xml file but in a large project like Cocoon it makes more sense to set the version number in one place only. Having thought this through some more I realize what I said is not strictly true. The version numbers specified by the pom file in the 'parent' folder sets the version number that all other artifacts that depend on this artifact should ask for. The version number specified in the artifact's local pom file effectively sets the version number of this artifact when it gets built. So to make this clearer if we take the 'cocoon-core' artifact; it's pom.xml file is defined in [cocoon trunk]\core\cocoon-core\pom.xml. It contains a couple of lines as follows: - artifactIdcocoon-core/artifactId version2.2.1-SNAPSHOT/version These effectively set the version number of this artifact when it gets built. However as I showed in my earlier email the pom.xml file in [cocoon trunk]\parent\pom.xml also specifies a version number (hopefully the same one!) and this is the one that other artifacts will look for if they express a dependency on it. I also realized that maybe I should explain a bit more about the difference between the development version of Cocoon and the 'released' version. The development version is obviously managed in a subversion repository. As this is usually in a state of flux it is quite common to set the version numbers defined by some code to end in -SNAPSHOT. This tells maven to check the repository to see if a slightly more up to date version is ready. However, you should never see a version ending in -SNAPSHOT on the public maven repository. In theory when a release is made only non-snapshot versions are copied onto the repository.

Re: AW: [C2.2] Display Upload Progress
Hi Matthias, Hi i compiled all the samples as you described. but when i type mvn -P allblocks jetty:run in core/cocoon-webapp i still have the problem with the missing artifacts. don't you have problem that maven wants to download artifacts that doesn't exist in the specified remote repositories? To check what's going on I've rebuilt Cocoon from the latest subversion copy. I deleted my maven repository (to ensure the build process starts from scratch). I updated my subversion copy of Cocoon. I ran 'mvn clean' Here I ran into a few error messages. Not sure why it would need a plugin in order to cleanup a few files: - ... from the specified remote repositories: central (http://repo1.maven.org/maven2) org.apache.cocoon:cocoon-maven-plugin:maven-plugin:1.0.0-RC1-SNAPSHOT I ignored this and then executed the main build command: - mvn install -P allblocks After a very long time and lots of messages and tests it built successfully: - [INFO] BUILD SUCCESSFUL [INFO] [INFO] Total time: 36 minutes 54 seconds [INFO] Finished at: Mon Jan 19 16:00:33 GMT 2009 [INFO] Final Memory: 134M/240M [INFO] D:\projects\cocoon\cocoontrunk Now for the moment of truth... to run the webapp! cd core\cocoon-webapp mvn jetty:run Uh oh! It runs jetty but only after spewing out loads of errors about bean configuration. I've attached the messages to this email. If I persevere and try accessing the sample webapp it not unexpectedly returns error 503 (Service unavailable). So... *I guess the answer is the subversion trunk is currently broken*... which is unfortunate for me because now I cannot run the examples either :-( I was using Maven version 2.0.9 which is the bare minimum you need to build Cocoon. As for accessing those other repositories I had no problem (even though I think it is probably time to remove the dependency on some things from Grek's personal site!). Actually, if you look in the 'parent' folder you will see these other repositories listed in the pom.xml: - repositories repository idcentral/id nameMaven central repository/name urlhttp://repo1.maven.org/maven2/url releases enabledtrue/enabled !-- only look for jars here when they are not present locally -- updatePolicynever/updatePolicy /releases snapshots enabledfalse/enabled /snapshots /repository !-- This is temporary repository -- repository idgkossakowski-maven2/id namegkossakowski-maven2/name urlhttp://people.apache.org/~gkossakowski/maven2/repository/url /repository /repositories Regards, David Legg INFO [main] (DefaultListableBeanFactory.java:467) - Overriding bean definition for bean 'org.apache.cocoon.caching.Even tRegistry': replacing [Generic bean: class [org.apache.cocoon.caching.impl.StoreEventRegistryImpl]; scope=singleton; abs tract=false; lazyInit=false; autowireMode=0; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=n ull; factoryMethodName=null; initMethodName=initialize; destroyMethodName=null; defined in URL [jar:file:/D:/projects/co coon/cocoontrunk/core/cocoon-webapp/target/cocoon-webapp/WEB-INF/lib/cocoon-eventcache-impl-1.0.0-SNAPSHOT.jar!/META-INF /cocoon/spring/cocoon-eventcache.xml]] with [Root bean: class [org.apache.cocoon.caching.impl.StoreEventRegistryImpl]; s cope=singleton; abstract=false; lazyInit=false; autowireMode=0; dependencyCheck=0; autowireCandidate=true; primary=false ; factoryBeanName=null; factoryMethodName=null; initMethodName=null; destroyMethodName=null] ERROR [main] (ContextLoader.java:215) - Context initialization failed org.springframework.beans.factory.BeanDefinitionStoreException: Unable to read Avalon configuration from 'resource://org /apache/cocoon/cocoon.xconf'.; nested exception is org.apache.avalon.framework.configuration.ConfigurationException: Una ble to create class for component with role org.apache.cocoon.caching.impl.JMSEventMessageListener with class: org.apach e.cocoon.caching.impl.JMSEventMessageListener at org.apache.cocoon.core.container.spring.avalon.BridgeElementParser.parse(BridgeElementParser.java:86) at org.springframework.beans.factory.xml.NamespaceHandlerSupport.parse(NamespaceHandlerSupport.java:69) at org.springframework.beans.factory.xml.BeanDefinitionParserDelegate.parseCustomElement(BeanDefinitionParserDel egate.java:1255) at org.springframework.beans.factory.xml.BeanDefinitionParserDelegate.parseCustomElement(BeanDefinitionParserDel egate.java:1245) at org.springframework.beans.factory.xml.DefaultBeanDefinitionDocumentReader.parseBeanDefinitions(DefaultBeanDef initionDocumentReader.java:135) at org.springframework.beans.factory.xml.DefaultBeanDefinitionDocumentReader.registerBeanDefinitions

C2.2 - Where is bu.js? (AJAX related)
I'm getting myself into a terrible mess trying to make a simple suggestion list using CFORMS and Ajax. I've no problem with the cocoon-webapp samples... they run fine. The problem arises in knowing which bits of the samples to extract to make a single stand-alone app. Perhaps I approached this process the wrong way around but I thought I'd start with a brand new Cocoon block fresh from running maven and build it up from that. I'm now getting a version of my form appearing in a browser but instead of a list of autocompleting names I get a plain textbox with an index number in it and a long exception list gets generated. The upshot of the exception list is a couple of missing pipeline matchers: - .. Caused by: org.apache.cocoon.ResourceNotFoundException: No pipeline matched request: resource/external/bu/manifest.js .. javax.servlet.ServletException: org.apache.cocoon.ResourceNotFoundException: No pipeline matched request: resource/external/bu.js ..

Hi Benjamin, Solution is to make sure you use the browser-update transformer correctly. Let me know if I am right. Thanks for the explanations. That makes a lot more sense.

Re: Serialize with type html removes input tags, why? How to fix?
Hi Smigge, There is a little more detailed account of how the default HTML serializer works here: - http://cocoon.zones.apache.org/daisy/documentation/components/1059/g1/896.html Both Jasha and I don't know what you mean when you say it drops stuff. Do you mean it completely removes the whole 'input' tag or somehow munges the attributes? If it's the latter then it may be something to do with how the default HTML serializer treats boolean attributes. For example, option selected=selected is output as option selected.

Re: How to force a Save As prompt?
Derek, Please add the reference/link for why URLs in Cocoon should not have an extension - I know its required, but why is it bad? It's not specific to Cocoon. I only mentioned that because Cocoon's sitemap makes it particularly easy to map a URL without an extension to some content. So in general, it is not a good idea to include extensions in a URL if you want that URL to be useful for a long time to come. The extension may contain implementation specific details which may not always be true. It's generally considered better to publish a generic URL and then let the browser use content negotiation to determine whether it can accept that content. For example, what if your organization regularly published an important document as a Microsoft Word file (*.doc) and published it on your site with a URL of: http://myorg.org/importantdocs/thisweek.doc That's great and you would probably bookmark it and everything would be fine... until your organization decided to move with the times and publish it as a styled xml document. Now you have a dilemma... do you change the url so it contains a .xml extension and risk losing your loyal followers (whose bookmarks no longer work) or do you keep the same url which ends in .doc but is actually an xml file? A great resource for all this is the W3C's own Cool URIs [1] page. There are a lot of other url advocates out there like this one [2]. I suppose though, if you are talking about downloads this might all be a bit academic. After all if you want to download an executable file the chances are it will remain in the same format forever... but you should at least spend half a second thinking about the format of the URL you expose it with.

Re: How to force a Save As prompt?
Derek, Before getting into detail, I'd like to say that I do agree in principle with what you said below. Oh Good! I was worried for a moment when I saw the size of your response ;-) My real issue probably lies in the fact that I have been around computers too long. Ah yes... I remember building my own bi-stable flip flop circuits! PS The answer to your question of Microsoft Word file is - neither!The existing URL (poor though it might be) is still a valid one and should be kept. Ok. I was thinking off the top of my head. A better example might be publishing a page with a URL of 'today.asp' or 'today.jsp'. The extension here is irrelevant and simply overcomplicates the URL for the poor humans that might have to type it in or remember it. I see URLs in a more semantic way now after following the workings of the semantic web crowd. Another simple example occurs with images. We don't really need to note the fact that an image is in gif format by stating that in a URL. Times change and it may be that for legal reasons you can no longer use GIF format at all on your site and you have to use PNG instead. So all those URL references to mylogo.gif have now got to change. Whereas if you had supplied a url of /images/mylogo the change would be invisible and the URL could remain unchanged. I think I'll stop now... I might catch the zealot bug ;-) Regards, David Legg - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: How to force a Save As prompt?
Mmmm... Does anyone still care about IE4 - the stats from different sites suggest not: By chance I came across another item [1] which seems to suggest that perhaps the problem is not exclusive to IE4. Maybe IE5 and IE6 are involved too. The article gets a few developers worked up after the beginning. My reading of it seems to imply that mime-sniffing takes place if IE can't work out the mime-type from the url. So if your url ends in .html you are ok, but if it ends in no extension (something which is considered good practice in Cocoon) it will sniff the file content and use that to decide what to do with the downloaded file. It would be interesting to know if anyone else has come across this issue with IE7.

Re: How to force a Save As prompt?
is there a way or workaround how i can force a Save As prompt for my cocoon output? The problem is that the browser knows the mime types of the generated files (xml, pdfs) and displays it instead of prompting. See http://markmail.org/message/jgcetksksgmpfk2c#query:cocoon%20content%20disposition%20header+page:1+mid:dt2547iguthv34dg+state:results (Content disposition header) Ah! this all brings back some memories. This article summarizes what you need nicely [1] Just for reference, I presume you don't care about IE4? The technique of setting the content-disposition header doesn't work for that browser because even if you used the content-disposition header it still sniffed the file you were downloading and acted on what it found there rather than what you told it [2].

Re: [C2.2] Overriding default properties? - SOLVED
I wrote: I'm a little confused about the best way to change or override default settings for properties in Cocoon 2.2.

I get no change in the output. Is this because the spring beans which define the default settings have a higher priority than the sitemap? I realize now that doing things this way is the 'old' or pre-cocoon 2.2 way and I must empty my head of such thoughts! As an experiment I located the following file: [cocoontrunk]/core/cocoon-pipeline/cocoon-pipeline-components/src/main/resources/META-INF/cocoon/spring/cocoon-core-serializers.xml which I believe to be the file responsible for setting the default properties of the 'xml', 'html' and 'xhtml' serializers as well as some others. I then copied this file to my own block here: [myblock]/src/main/resources/META-INF/cocoon/spring/serializers.xml I then edited this file to remove all the other bean definitions except the one with the name: 'org.apache.cocoon.serialization.Serializer/html'. I also changed the doctype-public and doctype-system to the HTML 4.01 strict definition. After restarting my C2.2 application I was pleased to see that the pipeline which had been outputting 4.01 loose doctype was now outputting 4.01 strict HTML as required. So it works! I have successfully overridden the default config for a Cocoon component without having to resort to the sitemap.xmap file. Having read other user's comments on this I can see how useful this is.

Check that you can see this file yourself. If you can't then that would be a problem. Alternatively, if you just type mvn archetype:generate without the -D option it should use the default maven archetype catalog where you should find Cocoon archetypes listed around entry 42 to 44 in the list. The reason we give you the -D option is for convenience so that new users aren't so scared of the long list of archetype possibilities!

Hi Martin, I think that the subversion checkout works well, but maven is the problem. I think your right.

Re: C22 - Maven artifact missing
Tak, Cocoon is a big project. Not all people need all features. For the newbies, we can always go back to the old tag that we know, and use that version. Could that be a solution? That's not the issue. One of the reasons for making Cocoon 2.2 the way it is is to allow people to only add the features (read Blocks) they require. So for example, in your case you wanted to use CForms and that's why you had to add the cocoon forms block to your list of dependencies.

Re: floating button in CForms
Hi Paul, I have a Lg CForm and the client would like the Save button to float so that it is always visible? I should think your best bet would be to use a CSS stylesheet to fix the position of the save button. You could treat the save button like the contents of a fixed footer at the bottom of the page. I'd suggest looking up the 'position:fixed' style. Be warned though that IE 5 and friends doesn't support this, so a work-around has to be done for those. I'd recommend the sitepoint book: 'The CSS Anthology: 101 Essential Tips, Tricks Hacks' [1] by Rachel Andrew if you are looking for ready made examples. [I'm not affiliated to this book in any way!]. Another approach might be to break up the form into smaller groups and only show one group at a time. An example can be found in the Multi-page wizard demo [2] Hope that helps.

Re: cforms
Hi Tak, How should I install Cforms block into getting-strat-app environment? Should I generate myBlock3 and copy cocoon-cforms-impl-1.1.0.jar (unzipped from the cform .zip file) into some directory and link all three blocks together? There is a tutorial on the Cocoon website showing how to add a Cocoon form under Cocoon 2.2 [1]. It may be a tiny bit out of date but it should tell you what you want to know. Just to recap; a Cocoon Block is nothing more than a jar file containing files in a certain expected directory structure. When you come to build a Cocoon application all you are doing is mixing the pre-built Cocoon Blocks that go with a certain release of Cocoon together with your own Cocoon blocks that get generated from your project's source and resource files. There is no need to create 'myBlock3' as that has effectively already been done for you... that is what the cocoon-forms-impl jar file is. All you have to do is tell Maven that your project depends on this jar by adding it to the dependency list in the pom.xml file and Maven will download it and install it into its own local repository ready to be added to the class path when you run your app. Hope that makes it clearer.

Re: Java bean puzzle. using ecliplse plugin or not.
Hi Grek,
Unfortunately, it's not fixed in trunk. Take a look at the history of
this file[1] and you will see that is has not changed for more than a
year now.
The problem we see here is that archetype plug-in for Maven tries to
find all expressions in files that it creates...
Unfortunately, #{message} is treated as an expression too but it
shouldn't. It's [not] aimed at archetype plug-in but Cocoon's
template generator.
According to this[2] page (archetype uses velocity) the fix should be
easy: we need to escape # character using \# and everything
should work just fine...
Aha! Well spotted ;-)
I'll try to fix this issue ASAP.
Thanks. As this is may be someone's very first close encounter with
Cocoon 2.2 we want to set a good example.

Can anyone explain this behaviour, in terms that a

I think the problem is that the

old version of the JX syntax for getting hold of a javabean's property.
Try editing the file so that instead of: -

Thankyou very much, David. I can confirm that the spring-bean now does
work properly.
Thanks for confirming that.
How do we report this to the developers?
Normally, you would open a new item in the bugs database (called JIRA) [1].
However, I've just looked at the latest version of that file in the SVN
repository and it looks like it is fixed already. I think it is in the
'trunk' at this location: -
[svn
trunk]\tools\archetypes\cocoon-22-archetype-block\src\main\resources\archetype-resources\src\main\resources\COB-INF\demo\spring-bean.jx.xml
The code looks like this: -
demo
module${groupId}:${artifactId}/module
spring#{message}/spring
/demo
I suspect though that getting this change incorporated into the wide
world is a little more involved than just issuing a new release of
Cocoon because someone has to upload the new version to the official
maven site I think.
Anyhow... the main thing is it has been covered and at some point the
corrected version will be available. In the meantime we can sit back;
smug in the knowledge that we know the answer ;-)

All I did to get the dependency tree listing was to add some exclusion tags to the myblock/pom.xml file to exclude commons-logging and log4j jar files from all of the dependencies listed in the pom. The reason I'm flagellating myself like this is because I need to effectively replace these two jar files with some slf4j equivalents that redirect log messages created using legacy (commons-logging and log4j) code to the slf4j logging framework. Since that message and thanks to the hint about 'mvn dependency:tree' from Reinhard I've realized that only cocoon-core has a dependency on those two jar files. I updated pom.xml to only have the exclusion tags on cocoon-core and now the dependency tree shows no reference to the two jar files I wanted to be excluded. This is great!... but my quest to use slf4j as my logging solution is still not fulfilled. The question now is why when I run 'mvn package' or 'mvn jetty:run' when in the myblock directory does maven insist on placing the commons-logging and log4j jar files into WEB-INF/lib even though I've expressly excluded them? Maybe the answer has something to do with the cocoon-maven-plugin? Also, since my last message, I came across the Shielded Classloader [2] which explicitly mentions the problem of using your own logging framework and how the shielded classloader may help. I'm hoping that once I have these issues sorted out I'll write it up to help others travelling this route for the first time.

Re: C2.2 - Cannot remove jar files from classpath using Maven
This is great!... but my quest to use slf4j as my logging solution is still not fulfilled. The question now is why when I run 'mvn package' or 'mvn jetty:run' when in the myblock directory does maven insist on placing the commons-logging and log4j jar files into WEB-INF/lib even though I've expressly excluded them? What WEB-INF/lib directory are you referring to? Is it ./target/rcl/webapp/WEB-INF/lib or is it the WEB-INF/lib directory of the web application Maven module? If it is the first, the answer is that the wrapper web application (a minimal web application that wraps a block) uses the reloading classloader (commons-jci.jar) which has a dependency on commons-logging. It is the first. I don't understand... if the wrapper web application depends on commons-logging and makes arrangements to load the commons-logging jar into the classpath it should clash when I attempt to load the jcl-over-slf4j jar file which is supposed to replace the classes in commons-logging so that messages get forwarded to the slf4j logging framework... but they don't! If I change the dependencies section of myblock/pom.xml to the following, then when I run mvn jetty:run I get bucketloads of debug messages on my console... which I think means SLF4J is working... or maybe I'm deceiving myself! dependencies dependency groupIdorg.apache.cocoon/groupId artifactIdcocoon-core/artifactId version2.2.0/version exclusions exclusion groupIdcommons-logging/groupId artifactIdcommons-logging/artifactId /exclusion exclusion groupIdlog4j/groupId artifactIdlog4j/artifactId /exclusion /exclusions /dependency dependency groupIdorg.apache.cocoon/groupId artifactIdcocoon-servlet-service-components/artifactId version1.0.0/version /dependency dependency groupIdorg.apache.cocoon/groupId artifactIdcocoon-template-impl/artifactId version1.1.0/version /dependency dependency groupIdorg.apache.cocoon/groupId artifactIdcocoon-flowscript-impl/artifactId version1.0.0/version /dependency dependency groupIdjavax.servlet/groupId artifactIdservlet-api/artifactId version2.4/version scopeprovided/scope /dependency !-- Logging related dependencies -- dependency groupIdorg.slf4j/groupId artifactIdjcl-over-slf4j/artifactId version1.5.2/version /dependency dependency groupIdorg.slf4j/groupId artifactIdlog4j-over-slf4j/artifactId version1.5.2/version /dependency dependency groupIdorg.slf4j/groupId artifactIdslf4j-api/artifactId version1.5.2/version /dependency dependency groupIdch.qos.logback/groupId artifactIdlogback-classic/artifactId version0.9.9/version /dependency /dependencies Regards, David Legg - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

C2.2 - Cannot remove jar files from classpath using Maven
In order to use another logging package I need to ensure commons-logging
and log4j jar files are not in the class path. I cannot get Maven to
exclude them. I'm using Maven 2.0.9.
Here's the scenario: -
Following the Cocoon tutorial [1] I created a Cocoon block called
'myblock' (number 2 on the list of archetypes)
If I change into the 'myblock' folder and run 'mvn package' I notice the
following lines in the output: -
...
[INFO] [cocoon:prepare {execution: prepare}]
[INFO] Preparing a Cocoon web application.
[INFO] Deploying string-template to WEB-INF/log4j.xml
[INFO] Adding lib to WEB-INF/lib: commons-logging:commons-logging:1.1:jar
[INFO] Adding lib to WEB-INF/lib:
org.apache.commons:commons-jci-core:1.0:jar
[INFO] Adding lib to WEB-INF/lib: commons-io:commons-io:1.3.1:jar
[INFO] Adding lib to WEB-INF/lib: log4j:log4j:1.2.14:jar
...
That means those jar files will be in the classpath when the web app is run.
So, then I edit the myblock/pom.xml file and add 'exclusion' tags to
all the dependencies I can see like this: -
project
...
dependencies
dependency
groupIdorg.apache.cocoon/groupId
artifactIdcocoon-core/artifactId
version2.2.0/version
exclusions
exclusion
groupIdcommons-logging/groupId
artifactIdcommons-logging/artifactId
/exclusion
/exclusions
/dependency
...
/dependencies
...
/project
When I run 'mvn clean package' I get exactly the same results!
When I use the mvn -X parameter to see the debug output as maven runs I
get the impression that the maven plugins seem to be adding dependencies
to the dependency tree: -
...
[DEBUG] Retrieving parent-POM: org.apache.cocoon:cocoon::6 for
project: null:cocoon-tools-modules:pom:6 from the repository.
[DEBUG] Adding managed dependencies for unknown:cocoon-maven-plugin
...
[DEBUG] commons-logging:commons-logging:jar:1.1
...
I suppose I could start fiddling with plugin exclusions but this is
getting silly. Do I really have to work this hard to try to make sure a
jar file isn't included in the classpath?

Use the Maven dependency plugin (the 'tree' goal) to find out what dependencies have a dependency on the libraries that you want to remove. Then you have to remove them from ALL occurrences by adding exclusions sections. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: C2.2 - Mixing SLF4J with Cocoon
Thanks for responding Ralph. Cocoon 2.2 is using commons-logging, so in the environment shown by your stack trace it would also be going to SLF4J and the SimpleLogger via the jcl adapter. I guess it would help to know what version of SLF4J is in use and where its jars are in the various places they could be. Maybe part of the problem is that the slf4j-log4j12 pom file on the Maven repo has a bad checksum: - Downloading: http://repo1.maven.org/maven2/org/slf4j/slf4j-log4j12/1.0.1/slf4j-log4j12-1.0.1.pom 406b downloaded [WARNING] *** CHECKSUM FAILED - Checksum failed on download: local = '37304fd56d9cdda797718e6710637d232986c442'; remote = '15558150f0136e9802bb95a347e0045fb4ffe697' - RETRYING Downloading: http://repo1.maven.org/maven2/org/slf4j/slf4j-log4j12/1.0.1/slf4j-log4j12-1.0.1.pom 406b downloaded [WARNING] *** CHECKSUM FAILED - Checksum failed on download: local = '37304fd56d9cdda797718e6710637d232986c442'; remote = '15558150f0136e9802bb95a347e0045fb4ffe697' - IGNORING Cocoon does not directly use Log4j. It uses an abstraction layer that defaults to log4j. slf4j is also an abstraction layer. In the stack trace you have shown below it is using its SimpleLogger implementation. This can be replaced with Logback, Log4j or java.util.logging. You might simply try replacing slf4j-simple.jar with slf4j-log4j12.jar. I'll give it a go but I'm not sure how to do that where Maven is involved. I guess I change a dependency in a pom.xml file? If I don't edit a file won't Maven simply put the old jar file in the classpath again? I've heard that Commons Logging is now considered evil by some. Would it make sense to try to get everything in my app to use SLF4J? Regards, David Legg - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Installing 2.2
Hi Patrick, Is it right, that one has just to fire mvn archetype:generate -DarchetypeCatalog=http://cocoon.apache.org and maven will install all (standard) dependencies transitive by itself (and copy everything into my local repository as always)? Pretty much! You should think of C2.2 applications as being a collection of different blocks some generated using the command you show above and some from different archetypes. Not all of your blocks have to be 'Cocoon blocks'. And how is one able to get the 'old' cocoon-samples page running (normally I've just hit mvn jetty:run to start the samples inside the svn-cocoon-trunk-version)? It sounds like you did all the right things except maybe you forgot to change into the '[cocoon trunk]\core\cocoon-webapp' folder and then issue the 'mvn jetty:run' command and view the result at 'http://localhost:/'.

Re: Installing 2.2
Patrick, It sounds like you did all the right things except maybe you forgot to change into the '[cocoon trunk]\core\cocoon-webapp' folder here is the problem. After downloading the 2.2.0 binary, there is no such folder. Should I better stick with a version from trunk during development ?? So building cocoon by myself is still the way to go (I mean with -P allblocks semantics etc. Ah! I see. What I would do is checkout the latest version from trunk (see [1] for details). But *don't* use this for development of your apps. Simply use it for reference. Once you have that installed you should be able to run the sample webapp as I described by changing into the '[cocoon trunk]\core\cocoon-webapp' folder and then typing 'mvn jetty:run' and viewing 'http://localhost:/'. When actually developing your own Cocoon web app follow the pattern shown in the tutorials [2]. If you want to do something in your own app that you've seen demonstrated in the sample app you could copy appropriate bits from the sample into your own blocks. For example you might see useful items in the sitemap or required dependencies in the pom.xml files or various configuration beans that you could adapt.

Re: Installing 2.2
Patrick, Why is there a binary download available, if (hopefully most) users build their apps with maven and dependencies are obtained automatically? I guess it's a comfort for those not able to use Maven for some reason. I think of it as a transitional thing. For those of us trying to get to grips with Maven, SSF, Blocks etc this is a scary time! The results are well worth it though. When I think back to the Joy I felt getting Bertrand's Cocoon Bricks demo working and how it magically patched various files automatically when a new version of Cocoon was released I knew there had to be a better way ;-) David Legg - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Installing 2.2
Hi Mika, as an semi-amateur web application developer I have to say that moving on to 2.2 has been too big step for me. Not familiar with the Maven and even figuring out of the examples has caused me pain to understand what's going on... I understand exactly what you mean ;-) So I would appreciate a lot if someone could wrote a stepping stone page to those who aren't familiar with the framework which 2.2 uses, but who know something about 2.1. Or does it already exist? Well... there was one attempt [1] but don't get your hopes up! I think you're right though. We do need something a bit more general than the tutorials [2] to introduce people to the new concepts used in Cocoon 2.2 Just as important we need to say where they fit in and what they replace compared to earlier versions. I did update the Cocoon tutorial recently [3]. If you haven't read it for a while have another look and see if it makes more sense to you. If I have time I'll see if I can create a more introductory page which could be read before following the tutorials.

C2.2 - Mixing SLF4J with Cocoon
I'm trying to add a new block to a Cocoon web app and every time I try to do a 'mvn jetty:run' command I get a 'java.lang.AbstractMethodError' and the web app just seems to stop serving web pages (error list shown at end of this message). The block in question makes calls to the Sesame [1] RDF triplestore. The important thing is that, like a lot of modern Java apps, Sesame makes use of SLF4J [2] to do its logging. I'm not familiar with the various logging frameworks but I think I've accidently walked into a minefield here! Cocoon seems to use Log4j, Jetty might be using something else and my block might need slf4j. Add to this that I've seen a report about slf4j not playing well with the Reloading Class Loader (RCL) and I think I'm well and truly stuffed! Please, if anyone knows how to get a library that uses slf4j to play nicely in a Cocoon environment I'd be very grateful ;-) Regards, David Legg Errors... ...

C2.2 - Web archetype whodunnit!
In true detective style I'm trying to work out whodunnit! It's probably the butler! but in case it's not I'd appreciate any help. I've successfully built a Cocoon block and a brand new Cocoon generator and between them created a pipline to produce some HTML. When I change into the Cocoon block's directory and type 'mvn jetty:run' all is well and I can view the block's output in a browser with no trouble. I now want to create a Cocoon web application block in order to generate a war file and also begin adding other blocks to handle other aspects of the web application. I've followed (and edited!) the tutorials so I wasn't expecting any problems here... but I wasn't so lucky! Having created the web app block (as per the deployment tutorial [1]) I updated the pom file so that the web app block knew about the other blocks. When I changed into the Web app block's directory and ran 'mvn jetty:run' I noticed a lot of messages scroll off the screen but Jetty seemed to launch ok. However when I try viewing the output in a browser I get 404 errors. So it looks like Jetty is running but the browser requests are either not being passed on to Cocoon at all or the Cocoon web app block is not passing the request on to the appropriate Cocoon block underneath it. The trouble is I'm looking at a lot of messages from various systems that mean nothing to me. When I looked at the messages that scrolled off the screen they contained the following: - [...] 2008-07-13 12:57:46.840::INFO: jetty-6.1.7 2008-07-13 12:57:53.708::INFO: No Transaction manager found - if your webapp requires one, please configure one. log4j:WARN No appenders could be found for logger (org.springframework.util.ClassUtils). log4j:WARN Please initialize the log4j system properly. 2008-07-13 12:57:55.126::WARN: failed [EMAIL PROTECTED]/,D:\projects\meerkat\meerkat-webapp\target\meerkat-webapp-1.0-SNAPSHOT} java.lang.AbstractMethodError: org.slf4j.impl.Log4jLoggerAdapter.trace(Ljava/lang/String;)V at org.apache.commons.logging.impl.SLF4JLog.trace(SLF4JLog.java:82) at org.springframework.core.CollectionFactory.createConcurrentMapIfPossible(CollectionFactory.java:195) at org.springframework.web.context.ContextLoader.clinit(ContextLoader.java:153) at org.springframework.web.context.ContextLoaderListener.createContextLoader(ContextLoaderListener.java:53) at org.springframework.web.context.ContextLoaderListener.contextInitialized(ContextLoaderListener.java:44) at org.mortbay.jetty.handler.ContextHandler.startContext(ContextHandler.java:540) [...] It looks like I've got a lot of homework to do... Should I be worried about not having a transaction manager? Do I need appenders for my logger? What might cause a java.lang.AbstractMethod error and where do I start looking? I'm willing to add additional documentation to the site but I suspect there are some fundamental things I need to add to the tutorial like how to set up the logger, how to do simple spring bean configuration and how the Cocoon web application archetype works.

I would like to write a custom Cocoon generator in a Cocoon 2.2 application. I've come across the excellent Creating a Generator [1] page on the Cocoon site but I haven't spotted how Cocoon knows that when you use map:generate type=bean / in the sitemap it should use the new class BeanGenerator as defined in the article. I understand the 'old' way of doing this by creating a sitemap.xconf file but I'd like to master the new technique. I suspect if I read and re-read the Cocoon spring configurator [2] pages it might sink in... but it would have to sink a long way ;-) Regards, David Legg [1] http://cocoon.apache.org/2.2/core-modules/core/2.2/688_1_1.html [2] http://cocoon.apache.org/subprojects/configuration/1.0/spring-configurator/1.0/1304_1_1.html - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Tutorial improvement suggestion
Grek, The only missing thing is the actual archetype catalog XML file. David, would you like to prepare own? I'm not sure how archetype plug-in supports this file generation but even if support is bad you could always prepare the catalog by hand (fortunately enough, the list is not long for us). I've generated the archetype catalog. I've attached it to this email. It wasn't too difficult... just had to run mvn archetype:crawl and it placed the new file in my local repository ([MAVEN_REPO]/.m2/repository/archetype-catalog.xml). I then edited this manually to change the order of the archetypes listed from simplest to most complex and added some human understandable descriptions. I've confirmed that the following command works with a local copy of the catalog: - mvn archetype:generate -DarchetypeCatalog=file://c:\temp\archetype-catalog.xml and generates the following interactive questions: - [INFO] Scanning for projects... [INFO] Searching repository for plugin with prefix: 'archetype'. ... [INFO] [archetype:generate] [INFO] Generating project in Interactive mode [INFO] No archetype defined. Using maven-archetype-quickstart (org.apache.maven. archetypes:maven-archetype-quickstart:1.0) Choose archetype: 1: local - cocoon-22-archetype-block-plain (Creates an empty Cocoon block) 2: local - cocoon-22-archetype-block (Creates a minimal Cocoon block) 3: local - cocoon-22-archetype-webapp (Creates a web application Cocoon block) Choose a number: (1/2/3): Choose archetype: There is a caveat though. I noticed on the Maven bug list [3] that some earlier versions of the plugin didn't handle local or remote catalog files. However this seems to have been fixed in the 2.0 alpha-3 version. So if someone would place this file on the site and update the documentation page we should be good to go. I registered on the Cocoon documentation site [2] to see if I could update the pages myself but quickly discovered this doesn't let me actually create or edit the documentation :-( Of course this file will have to be updated from time to time.

Tutorial improvement suggestion
Just thought I'd mention a tiny improvement that could be made to the Your first Cocoon application using Maven 2 [1] web page. The section titled Creating a block gives a maven command which uses the deprecated goal archetype:create instead of archetype:generate leading to the following disconcerting message during the build: - [INFO] [archetype:create] [WARNING] This goal is deprecated. Please use mvn archetype:generate instead If I use archetype:generate instead then Maven interactively asks me some questions I have to guess the answers to ;-) Regards, David Legg [1] http://cocoon.zones.apache.org/dev-docs/2.2/1159_1_1.html - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Tutorial improvement suggestion
Grek, The section titled Creating a block gives a maven command which uses the deprecated goal archetype:create instead of archetype:generate 1. Let's switch to interactive mode and provide archetype catalog... 2. Give up interactive mode completely and stick to utterly long command... The question is which one we prefer? What do you, dear users, think about it? I think I prefer option 1 as well. I don't mind the interactivity as it helps beginners get it right first time... especially if you give clear instructions in the tutorial about what to answer at each prompt and what the answers mean. The Maven manual page for this plugin [1] is more like I would expect to see in the tutorial (although I'd definitely want the responses highlighted though). I can't believe that Maven attempts to list *every* archetype. That list is going to get awfully long, very quickly.

C2.2 Tutorial comment
I've been prompted by the recent C2.2 release announcement to follow the web tutorial [1]. On the whole it's been very good but I've come across a stumbling block (no pun intended!) toward the end of the series.

Re: Cocoon Sparql Transformer ?
Hi Bernard, So I'm looking for a Sparql Cocoon Transformer both to extract triples with a SELECT query ... ... or to build others triples tith a CONSTRUCT query ... ... to be able to send this result to a XSLT transformer for exemple ... ... and then produce some Web Page I've toyed with this idea too. You may want to check out Fresnel [1]. When you think about it, RDF deals with graphs and graphs are difficult to manipulate with XPath (and hence XSLT) because XPath assumes the data is in the form of a tree. Fresnel is a bit like XSLT for RDF. Given a set of instructions, some RDF data and a location in the RDF to be displayed it transforms some or all of the RDF into a DOM tree and then optionally formats the tree ready for display on a web page or further processing using XSLT. Now the question is... how to fit it into Cocoon in a modular way! David Legg.

I understand ;-) Maven does all the 'installing' for you. As I said, Cocoon 2.2 is very different from earlier versions. Maven is the key. If you run Maven from the command line as shown in the tutorial [1] it will download what it needs from a remote repository and build a skeletal Cocoon 2.2 application for you. Then you have to figure out how to split up your existing app into suitable blocks and fit them into the new structure. Following the other tutorials in sequence will help you understand how to connect up other blocks.

Hi Fawzib, The main overview of Cocoon 2.2 can be found on the apache web site. [1] You should also take a close look at the section titled 'Your first Cocoon application using Maven 2' [2] Cocoon 2.2 is radically different but I definitely think it's worth it. The fact it uses Maven and Spring and makes a decent attempt to modularize are reasons enough for me to update. Keep in mind that you no longer get a bucket-load of examples ready to run once you have built it and the documentation is still very fragmentary at this stage.

O'Reilly also do a Hibernate A Developer's Notebook in the same series which I found very readable too. I might get shot for this... but I'd be tempted to use the 'Singleton' pattern to manage the Spring context. I think the 'proper' way to do it is to create your own Cocoon component which implements ThreadSafe and Contextualizable. You could then create and inject the Spring context into this at initialization time. It should then be available from the context of your application and not have to be explicitly passed around as a parameter.

Fresnel + Cocoon = Metadata Marriage made in heaven?
Sorry for the cryptic subject line! In essence I'm wrestling with a conceptual problem... how to format information for presentation in a manageable way. In most Database projects you have a fixed schema that rarely changes except perhaps when the project is revised. My data will be in the form of RDF in which the properties radiating from a resource can be many and varied. Worse still, new types of RDF resources could be added on a daily basis. An update cycle which involves manually re-writing an XSLT style sheet every day is untenable! If you haven't come across it yet, Fresnel [1][2] is a newish language that allows you to express which bits of a given RDF resource should be displayed, which bits shouldn't, the order in which they should be listed, what styles should be applied to it, etc. In many ways it looks to me to be a sort of XSLT for RDF. It uses an XPATH selector-like structure to specify RDF resources and its own OWL based language to define the transformations. The result is an XML tree structure; ripe for processing through Cocoon's pipeline. Some older Cocoon users may even recognize Stefano Mazzocchi's name in the contributor list ;-) With Fresnel, it might be possible to dynamically add new resource formatting instructions and hence solve the problem. Has anyone looked at using an implementation of Fresnel in a Cocoon project? Has anyone got any constructive ideas on how to employ Cocoon to format data in a dynamic, non-manually updateable fashion?
