I also copied all the libs plus the cocoon-scratchpad and added it to my classpath and still no good... :( but there are backups :) Could you tell me the steps that i have to go, so i can pass to the iterpreted engine? it's only a change to the cocoon.xconf: comment out the following lines: sitemap class=org.apache.cocoon.sitemap.SitemapManager file=sitemap.xmap reload-method=synchron check-reload=yes logger=sitemap/ and enable the following line: !-- sitemap logger=sitemap/ -- thus change it to: sitemap logger=sitemap/ However, this will not help you with your transformer problem. I've had a quick look at the code you sent earlier, and the problem might be with your endElement calls, currently they are like: super.endElement(NAMESPACE, ARTICLE_ELEMENT, ); but you should provide a value for the qName, and your code would be easier to read if you just pass on the values you get as arguments: super.endElement(namespaceURI, localName, qName); -- Bruno Dumon http://outerthought.org/ Outerthought - Open Source, Java XML Competence Support Center [EMAIL PROTECTED] [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

For an easy setup to get continuous integration of your project with newer Cocoon releases, see the following page on the wiki: http://wiki.cocoondev.org/Wiki.jsp?page=YourCocoonBasedProject But for starters, if you keep all your stuff in your own subdirectory with a subsitemap, and simply add one jar with your own classes to the WEB-INF/lib dir, things should be easy enough I guess? (maybe you don't know about subsitemaps etc. yet, in that case I recommend to investigate the default Cocoon webapp and to browse around in the documentation and on the wiki). -- Bruno Dumon http://outerthought.org/ Outerthought - Open Source, Java XML Competence Support Center [EMAIL PROTECTED] [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Because i am trying to follow the instructions on the wiki, I would suggest first trying to get your project working on Cocoon 2.1, and only after that try to automate things using the wiki-description. i will try to create my project outside the cocoon folder and change the $cocoon-root/sitemap.xmap so i create a mount point to my directory. It would be better if you let your build script copy your directory to the cocoon webapp. The root sitemap contains an automount mount statement that will automatically mount any subdirectories. and now my doubt ... the transformer mentioned above imported org.apache.cocoon.*, do i have to copy the cocoon.jar and all the other libs needed by cocoon to my project libs directory?? or is there another way? Instead of copying them, let your build script directly point to the WEB-INF/lib directory of the webapp. Don't expect me to hold your hand during all this however. -- Bruno Dumon http://outerthought.org/ Outerthought - Open Source, Java XML Competence Support Center [EMAIL PROTECTED] [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
