As we discussed earlier, the only integration with the existing approach would be at the repository level. I understand it's not acceptable from a pure OO design, but IMHO it's a valid approach for a content oriented application where the main contract is the consensus on the semantics of the node types. IMHO applications working on top of JCR should be ready to let other apps to modify the underlying content bypassing the object model layer. That would allow breaking the data silo in favor of publishing the content via multiple interfaces. I'd like to make clear that I'm not in a crusade in favor of jcr.

I like an application which makes abstraction on the technology to used. I don't know how we can provide both solutions in the Graffito project for the same target. This project is not always clear for some people. So supporting both approach will add more complexities to understand our goals. Now, it should be nice to get feedback/comments from others. Furthermore, J2 has its own object model. Adding cms features into J2, is it not supporting the J2 object model in a content repo in order to have features like versionning, locking, search, ... ?

Re: portlet content mode prototype
Edgar, Thanks for the clarifications. Running the process is responsability of the BPM engine, the jcr implementation wouldn't be responsible of running the process, it would be responsible only of storing the process definitions and process instances. Yes I know but when you are coming in some states, the BPM engine can start automatically some scripts. So, I was just wondering what kind of API we can use. great!. btw, It's probably a good example for trying to integrate both approaches. the approach is quite different. We are using the Graffito API. btw, the graffito api will be extended with workflow capabilities? Yes. This is just a prototype with a very simple workflow API. what engine, if any, are you using in the contribution?. By default it uses Osworkflow for mainly licence issues and it is a easy workflow engine. if possible, I would like to give the flexibilty to plug any kind of workflow engine. JPBM is very interesting but I'm not sure that we can use it in the ASF due to some licence issues. We can review this point. -- Best regards, Christophe

Wondering why the two jars must go in endorsed directly, and not in the WEB-INF/lib directory. I'm not sure :(, I think I read in jackrabbit mailing list that it was the right way to go but I didn't investigate further. It was just a quick fix to make it work. with java 2 jackrabbit worked without problems, but in java 5 those libraries were removed and some problems araised. Could you upload your versions of the jars for us, thanks! you can download it from http://www.apache.org/dist/xml/xalan-j/xalan-j_2_7_0-bin.zip Rememeber to remove every file in /tmp/jackrabbit before trying to start jetspeed again. br, edgar

See http://issues.apache.org/jira/browse/JCR-46 for the background. Java 5 uses the core classloader to load the TransformerFactory implementation specified in the javax.xml.transform.TransformerFactory property. This is why the class needs to be in the endorsed directory instead of the normal classpath location if you want to use another transformer than the one included by default in Java 5. For Jackrabbit the problem was that our XSL transformation was using features not included in the default compiling transformer implementation in Java 5. Not having looked at the issue here I'm not sure if the same thing applies. Just reacting to Edgar's comment. :-) BR, Jukka Zitting -- Yukatan - http://yukatan.fi/ - [EMAIL PROTECTED] Software craftsmanship, JCR consulting, and Java development

Re: portlet content mode prototype
Edgar Poce wrote: hi, I made a prototype of a wysiwyg portlet on top of jcr that allows to version the content. It's just a prototype of what I consider a portlet content mode should have, e.g. versioning, locking, tagging, audit, event notification, metadata. e.g. dublin core, i18n a portlet root per locale, publishing (staging) other workflow processes. The versioning GUI is available in edit mode as a menu that invoke remote dialogs powered by dojo javascipt toolkit. The portlet allows the user to edit the html, make the html versionable, checkin, checkout and restore a version. I didn't configure the webdav servlet, but it should be pretty easy. In the prototype a content portlet (i.e. wysiwyg portlet) must inherit a superclass that creates the portlet root node and adds a menu in edit mode. btw, is there any extension mechanism to add new portlet modes in jetspeed? download from: http://people.apache.org/~edgarpoce/graffito-jcr-portlets-1.0.war http://people.apache.org/~edgarpoce/graffito-jcr-portlets.tar.gz the war is self contained, just drop it in j2 and it should work. it creates a jackrabbit repository at /tmp/jackrabbit. It was tested in ubuntu, firefox, java5, jetspeed 2.0 installer with derby embedded. This sounds very nice. I deployed this to jetspeed. I have configured jetspeed + graffito to use Mysql. The portlet fails to display content .

Any pointers ? Thanks, Ruchi br, edgar
Re: portlet content mode prototype
Hi First of all take into account that it's just a prototype, it's not intended for use out of the box :) On 9/5/06, ruchi goel [EMAIL PROTECTED] wrote: Looks like this is internally using derby because I can login to see graffito portlets working in jetspeed portal. The prototype uses jackrabbit to store the html. Any pointers ? I think that the repository could not be initiated. I added more logging in a new version I deployed that would help to see the cause, try the new war. Note that the jackrabbit repository is created under /tmp/jackrabbit, so please make sure that the user who runs jetspeed has write access to that directory. br, edgar Thanks, Ruchi br, edgar

In you case, you will certainly use only one content repo but the worfklow service have to work with multpiple content repo (JCR based or not). A first level of integration would be on process definitions. What I'm trying to say is that as long as process definitions are stored in the repository with public semantics, any client can create new process definition via graffito api, a content portlet (as the wysiwyg prototype), webdav, etc. A second level of integration would be to store process instances in the repository. Local and remote clients could create a new process instance, or take a running process instance, acquire a lock on it, and signal the process. The process logic can modify one repository, many, or none. The API of the workflow depends on the engine, I mean that the BPM framework would be responsible of running the processes. * What if we are not using a JCR store ? * When you are moving into a specific workflow state, you may run some code to manage the content (move a content, delete, update, ...). How to do it (with the JCR API or the Graffito API ? I evaluated a couple of workflows for my daily job an I use JBPM pretty much. AFAIK, in any BPM engine, it doesn't matter whether actions in transitions modify jcr nodes, graffito objects, send mails, or whatever. Running the process is responsability of the BPM engine, the jcr implementation wouldn't be responsible of running the process, it would be responsible only of storing the process definitions and process instances. great!. btw, It's probably a good example for trying to integrate both approaches. the approach is quite different.
