Cocoon1 - Cocoon2
Hi guys, I've had a simple java code which produced XML output. In Cocoon1, I had to implement some Producer interface, so my java code became integrated in the Cocoon servlet. Does anybody know how to do similar thing in Cocoon2 ? I've read the code snippet written by Jupin, but I have something else in my mind. I don't want to send an other HTTP request to Cocoon, I want to write string XML directly into the pipeline. I guess I would have to implement some kind of a generator. Can somebody help me ? I want to port my cocoon1 implementation to cocoon2.

RE: Cocoon 2.0.1 Problem changing default parser to Xerces...
This error ([CONFLICT] lifestyle interfaces) was fixed after 2.0.1 release. Either get CVS version or get XercesParser.java from the CVS (cvs.apache.org) Vadim From: SANSONE, AARON M [Non-Pharmacia/1000] According to documentation, to change the default XML Parser to user Xerces (as opposed to JAXP), the following two steps must be taken: 1) Add -Dorg.apache.cocoon.components.parser.Parser=org.apache.cocoon.componen ts.p arser.XercesParser to the JVM Startup args for your servlet engine. 2) Place the following line in the cocoon.xconf: parser class=org.apache.cocoon.components.parser.XercesParser logger=core.parser/ This worked for me in Cocoon 2.0. However now that I moved to 2.0.1, this causes an exception and fails to initialize Cocoon. If I remove the above steps, Cocoon runs. However I am getting other exceptions that may be caused by my change in parsers. What is the appropriate way to override the default parser now?

Should I implement the Generator interface too in my servlet, or do the HTTP request thing what Jupin suggested ? Or is there any other way to do that ?

Cocoon2 and LDAP
Hi we tried to install LDAP in our Cocoon 2.0 environment. I downloaded jndi1.2.2 and put the jar file in the lib directory. In the sitemap.xmap we included the line map:transformer name=ldap src=org.apache.cocoon.transformation.LDAPTransformer/ After the restart we got the error message: ERROR (2002-02-13) 07:36.19:802 [cocoon ] (/cocoon/pathfinder/index.xml) ExecuteThread: '10' for queue: 'default'/GeneratorSelector: Could not set up Component for hint: org/apache/cocoon/www/sitemap_xmap org.apache.avalon.framework.configuration.ConfigurationException: Error in sitemap configuration : org.apache.cocoon.transformation.ldapTransformer ... java.lang.ClassNotFoundException: org.apache.cocoon.transformation.ldapTransformer ... When we removed the line in the sitemap.xmap the error was still there, -- the sitemap did not compile.

C2 Deployment
Hello C2 Users, How can I deploy C2 in two separate jars/wars ? In one of them,I´d like to put C2 core (as it comes from Apache site) and in the other I´d like to put my xsp,xml and xsl,so I need not to recompile the entire aplication when I change one of my xsp.

RE: session attributes in XSL Transformer

In fact, does something like map:transform src=w4b-xsl/style.xsl map:parameter name=use-request-parameters value=true/ /map:transform exist for session attributes? Nope.

RE: servlet, generator or ... (design question)
From: Mike Haarman [mailto:[EMAIL PROTECTED]] We are evaluating C2 for a very large, public, data-dissemination project (NHGIS.ORG). I would like to build a few small XML visualization tools in C2 for demonstration purposes. For example, a facility to upload an XML instance, associate it with a stylesheet living on the server and return transformed XHTML. The upload need not be saved anywhere on the server; I'd like to hand the uploading stream directly to Cocoon. I can clearly see a couple ways to accomplish this but suspect there are more: a) Specify a servlet external to Cocoon which handles multi-part form data as the src attr on my generator in the pipeline. How does this kick off the pipeline's processing? I suspect I need to bind the upload stream to the pipeline within my servlet and make a call to Cocoon but I'm not clear how. Or is Cocoon waiting like a daemon for bytes to show up at the mouth of the pipe? Not possible. b) Extend one of Cocoon's generator classes (StreamGenerator?) to handle the multi-part form data and call it from my form. Way to go. Yes, StreamGenerator. c) Is there a way to modify the File Upload example to hand the upcoming stream to a transformation? It seems that example merely specifies a directory for uploads and does nothing with the stream itself. It has different purpose; it supposed usage is to upload binary resources, not the XML which requires further processing. Vadim d) ? What is the cleanest manner of doing this?

RE: UnnamedSelector: ComponentSelector could not find the component on custom Action
ok...I was right - it was something stupid. I was inheriting from ConfigurableComposerAction but then masking the ComponenetManager variable in my class, and not providing an implementation of compose() to correspond. Looking up componenets off of a null ComponenetManager doesn't appear to work very well.

RE: New release 2.0.1 woes. Continue.
From: Alexander Smirnoff [mailto:[EMAIL PROTECTED]] OK. I've got it. Thanks. Welcome. I understand the motivation to exlude autocomplete is to speed up the pipeline process. So XSP developer must be responsible of consistent closing of his elements if he or she wants to return somewhere from the middle of XSP logic. Exactly. General note: it seems 2.0.1 compared with 2rc1 is significally slower for more or less complicated XSP. Can you pinpoint the reason of slowdown? I'm not sure that there are significant changes in the XSP machinery between these two versions.

And even if you use it in the main XSP method (despite the fact that it is not recommended), XSP engine can cover your mistakes if you set autocomplete-documents to true.

RE: [Action] Best practices for authentication
From: Pascal Davoust [mailto:[EMAIL PROTECTED]] Hi all, I've been experimenting with Cocoon 2.0.1 (and before that with Cocoon 1, but didn't do much with it because of the lack of features more than available in C2 now, mainly actions). And now I'm wondering about the 'protected' sample in the distro. Basically, having a page protected by authentication involves an action (DatabaseAuthenitcatorAction, in this case) to check that authentication was successful before serving the resource (understand: page), or redirect to login if authentication failed. The pattern for this is basically: map:match pattern=matching-pattern map:act type=session-validator !-- The protected (needing authentication) content -- /map:act map:redirect-to uri=login/ And if I correctly understand, it means that I've got to specify that schema for *every* match I want to protect, right? Seems a bit of overhead to me (may increase the maintenance cost for the sitemap)... Is there a smarter way of doing this? Quite frankly, that's the only one I see (I came to that conclusion myself *before* seing the protected sample)... but you guys have zillion times more experience than me with this topic! :) Reverse this, action before match: !-- have login before action to avoid loop -- map:match pattern=login ... /map:match map:act type=session-validator !-- The protected (needing authentication) content -- map:match pattern=matching-pattern1 ... /map:match map:match pattern=matching-pattern2 ... /map:match /map:act !-- Nothing is unprotected -- map:redirect-to uri=login/ (this is supported since 2.0.1) By the way, C2 rocks! :) Thanks!

Error handling design question
After playing with cocoon for few month I found that it quite strong and bold to be used in production environment. But there are some weak points which I've noticed. One of those is abnormal situation handling in XSP files. So far I've tried few approaches. The requirement is : In the case of error present XML message containing the error number and the reason of error occurred. First straight-forward approach was to use request.sendRedirect(messagepage) method. But this in some cases will result in IllegalStateException. Second (which we are using in our application) is embedded message approach. In the case of error message is embedded in XSP and later in the pipeline is filtered from excessive tags. The only drawback of this approach is that in some cases the execution of XSP must be terminated with return statement or throwing an exception, which means all open SAX events must be consistently closed. Using autocomplete-documents will cause additional CPU load. Maybe there are better solutions? I'll appreciate to get some new opinion about this issue.

PDF Table Template?
Hello, I am attempting to use the stylesheet included below to transform an XML file to PDF using Cocoon 2.0.1. My hope to build multiple tables in the PDF file. I have created two templates in the stylesheet for opening and closing a table. When running this through Cocoon, I get a NullPointerException in Xalan (TransformerImpl.run(TransformerImpl.java:3174)). If I uncomment the fo:table tags in the stylesheet comment the call to the two templates, it runs fine through Cocoon. Since I will create about 6 tables in this file, I would like to have a template to open the table and setup the columns instead of coding the same thing several times.

RE: [Action] Best practices for authentication
Mmh, I probably missed something here... I tried what you proposed, but I get a compilation error. Here's what I did at first, which works correctly: map:pipeline map:match pattern=account !-- Makes sure that authentication has been successful -- map:act type=session-validator map:parameter name=descriptor value=file://config/session-params.xml/ map:parameter name=validate value=user/login/ !-- The protected content for that match -- /map:act /map:match /map:pipeline (login is in another pipeline... does it matter?) And then I tried to reverse the pattern, like this: map:pipeline !-- Makes sure that authentication has been successful -- map:act type=session-validator map:parameter name=descriptor value=file://config/session-params.xml/ map:parameter name=validate value=user/login/ map:match pattern=account !-- The protected content for that match -- /map:match /map:act /map:pipeline And I get an error, which is : Error compiling sitemap_xmap: Line 901, column 6: Undefined variable: param I had a look to the source code, it's obviously missing the variable declaration. Did I forget something here? By the way, I found that the context://... specifier as a parameter value for the action descriptor doesn't work (did I correctly understand that this sub-protocol is related to the sitemap?), whereas file:// does the trick (I want to specify a path relative to the sitemap its written into).

RE: Cocoon, XForms, ExFormula, Chiba, Struts, etc
That sounds good. We've used Castor for successfully binding heavy XML traffic. Have you coordinated efforts with the folks that started ExFormula. I see that Chris is still active on the Cocoon list. The reason why I am opening this subject again is because I think it can add significant value to Cocoon. I am prepared to put some time working on this. Please let me know if we should keep this discussion in the dev mailing list. So, as briefly as I can, I'll share my experience and ideas: For those who haven't used Struts: It is a succesful Apache project (http://jakarta.apache.org/struts) which automates the task of mapping html forms to value objects used in an application domain. It's expected to influence directly the following JSRs: JavaServer Faces JSR: http://jcp.org/jsr/detail/127.jsp JSP 1.4 JSR: http://jcp.org/jsr/detail/152.jsp If it's so good, why are you posting on this list ? Struts is great with HTML forms. However it doesn't deal nor it plans to deal with any other sort of media. It doesn't take into perspective web services for example. We want to reuse the interface layer for SOAP clients as well. For some time now our project had pending requirements for web services support. We want to let other companies integrate with our portal. A reason why we keep pushing this requirement off is that it can't happen easy. All our external interface have been tied to JSP+Struts. Since we want to allow customers to do through web services what they could do through the regular Web UI, we'll need to write a brand new interface layer. We won't be able to reuse the automatic population and validation that we have for the HTML interface. Being a Cocoon newbie, I might be totally wrong, but it appears that the current Cocoon architecture is also focused towards HTML form validation (through rules for HTTP POST/GET params), but it also does not try to deal with other media like SOAP. Last October there has been an interesting discussion on the Cocoon mailing list about integrating server side XForms. I found it quite interesting, because based on my experience I do believe there is a farely good chance that XForms (or some limited version) can be successfully integrated in Cocoon so that data validation and java binding code (two way: web client - XML - Java domain objects) can be easily reused for clients ranging from HTML to SOAP. I also believe that this can be achieved with a sufficiently high performance (in many cases the WebClient - JavaObjects transformation can be achieved without necessarily going through naive XML representation. Instead using SAX events and JAXB ). Additionally data validation can be probably achieved elegantly through parser (xerces2) validation against XML Schema. Berin, Chris, Torsten and others seem to have made similar observation and have therefore started ExFormula last year. Chiba looks promising too. Can we try to unify and finish the job started, so that Cocoon moves to the next level.
