Stuck on Hello World, with non-FAQ Problem
Hi guys, I'm following along in the book Cocoon: Building XML Applications and trying to get the Hello World example to work. BEFORE you delete my email, PLEASE take a quick look at the really simple files and config info below and see if you can help me. I would REALLY appreciate the help so that I can learn. First, the version info: Cocoon 2.0.3 (latest stable release, obtained in binary form) JDK: 1.4 Tomcat 4.1.12 (just obtained about a week ago in binary form) OS: Redhat 7.3 The error: The requested URI /cocoon/helloworld was not found. Now, the pipeline config info in sitemap.xmap: map:pipelines map:pipeline map:match pattern=helloworld map:generate src=helloworld.xml/ map:transform src=helloworld2html.xsl/ map:serialize/ /map:match /map:pipeline /map:pipelines Note that, for ultra simplicity, this is the ENTIRE map:pipelines section (I deleted the rest). Ok, now here's the simple contents of the helloworld.xml file: ?xml version=1.0 document textHello World/text /document And of the helloworld2html.xsl file: ?xml version=1.0? xsl:stylesheet version=1.0 xmlns:xsl=http://www.w3.org/1999/XSL/Transform; xsl:template match=document html body h1xsl:value-of select=text//h1 /body /html /xsl:template /xsl:stylesheet Basically, with the modified sitemap the URI helloworld can't be mapped to anything and yet the original Cocoon welcome page and other pages it links to still come up. Also, here's the sitemap tag in $COCOON_HOME/WEB-INF/cocoon.xconf: sitemap check-reload=yes class=org.apache.cocoon.sitemap.SitemapManager file=sitemap.xmap logger=sitemap reload-method=synchron/ *The check-reload and reload-methods look like what they should be for the sitemap to be reloaded upon being changed and before serving any new requests. *I also tried stopping and restarting Tomcat. *I both flushed and turn off Konqueror's cache as well. Could it have something to do with Cocoon's cache itself?? I would be very happy if one of you could take the time to point me in the right direction. I'm a newbie, I know, but I'd like to become the next happy Cocoon user.

Now, the pipeline config info in sitemap.xmap: I could have wild guess at this since I just was confused looking at a helloworld example myself. But of course, your problem could be entirely different from mine. Anyway, try access with cocoon/helloworld/helloworld instead. You'll need that if your sitemap is a dir of its own.

Re: Stuck on Hello World, with non-FAQ Problem
Hi, I should have mentioned that sitemap.xmap is in $COCOON_HOME, where it is supposed to be from what I've read. I tried your suggestion, and got the same error. Btw, can anyone tell me why there are MULTIPLE sitemap.xmap files in $COCOON_HOME subdirectories? I thought there was only supposed to be the one in $COCOON_HOME. If anyone can help me out with my original Hello World question, I would REALLY appreciate it..I want to get this to work sooo much. Thanks again. :-) Sonny --- Kjetil Kjernsmo [EMAIL PROTECTED] wrote: On Monday 07 October 2002 19:24, Sonny Sukumar wrote: The error: The requested URI /cocoon/helloworld was not found.

RE: Stuck on Hello World, with non-FAQ Problem
On a fresh Tomcat (4.1.12) installation I copied the file cocoon.war (this is Cocoon 2.0.3) into the $TOMCAT_HOME/webapps directory. I then started Tomcat using $TOMCAT_HOME/bin/startup.sh, navigated to http://localhost:8080/cocoon and Tomcat expanded cocoon.war into $TOMCAT_HOME/webapps/cocoon, started the Cocoon servlet, and displayed the Cocoon intro page. As I said before, to do this Hello World example, I modified the map:pipelines section of sitemap.xmap to just contain the map:pipeline for the Hello World example. Actually, first I tried just adding the Hello World pipeline...when that didn't work I deleted the rest. It still doesn't work. And I'm not sure how Tomcat could be running some other Cocoon instance either. But I am obviously missing something somewhere. And thanks for the info on the parent-child sitemaps..I guess I'll get to that later, once I get this to work. :-) --- Hunsberger, Peter [EMAIL PROTECTED] wrote: I also don't understand why the other Cocoon pages still come up after I deleted ALL the other stuff inside the map:pipelines tag other than my map:pipeline for the Hello World example that generates from helloworld.xml, transforms with helloworld2html.xsl and serializes the output.

Re: Stuck on Hello World, with non-FAQ Problem
I switched treeprocessor by commenting out one sitemap tag and uncommenting the other one in cocoon.xconf. Btw, what is stored in Tomcat's work directory? This might sound like a dumb question to you, but I'm still on Hello World. :-) Likewise, I haven't done anything with error handling, so if you feel this is something important that I should do here and now to diagnose the problem, I humbly ask for a small explanation so I can understand what's going on. For example, what XML source does the error2html.xsl file in your sample code operate on? Lastly, I know for a fact I'm editing sitemap.xmap and not the sitemap.xmap.bak file I created to simply backup the original sitemap.xmap file before I started playing around with it. But it is good of you to point out. :-) Sonny --- Steven Noels [EMAIL PROTECTED] wrote: Sonny Sukumar wrote: The problem *is* a Cocoon problem.

This might sound like a dumb question to you, but I'm still on Hello World. :-) using the (default) compiled sitemap processor, the java classes that implement your sitemap (which are generated using xslt from your sitemap.xmap - don't ask ;-) are created there and compiled many people have experienced already that for some mysterious reasons, getting rid of these java sources/compiled classes sometimes does help Likewise, I haven't done anything with error handling, so if you feel this is something important that I should do here and now to diagnose the problem, I humbly ask for a small explanation so I can understand what's going on. For example, what XML source does the error2html.xsl file in your sample code operate on? not exactly a 'source', but a built-in error generator that provides the error2html.xsl stylesheet with an XML representation of the exception/stacktrace Lastly, I know for a fact I'm editing sitemap.xmap and not the sitemap.xmap.bak file I created to simply backup the original sitemap.xmap file before I started playing around with it.

Re: Stuck on Hello World, with non-FAQ Problem
Man, Steven, thanks for pointing that out--the Hello World example works now. The really weird thing is that I *did* check that quite a few times and fixed the missing ? mark before. However, I had made a backup copy of the helloworld.xml file so that I could delete my whole cocoon directory and reinstall cocoon from scratch (I thought I might have messed up the installation somehow). So I guess the backed up helloworld.xml file still had the missing ? and that's been a major culprit here. Sigh Also weird: Remember that I kept getting the error about cocoon/helloworld being an unknown URI? That error has mysteriously gone away...could it have been cleaning out the $TOMCAT_HOME/work directory that did it?? In any case, the example finally works!! Hooraaay!!! And it was supposed to be a trivial example too. :-) Go get some sleep--you have earned it. :-) Thanks!

RE: Stuck on Hello World, with non-FAQ Problem
- Make sure you xml declaration in helloworld.xml is ?xml version=1.0? (in your email it reads: ?xml version=1.0, missing the ending ? - hopefully that was just a typo. - Try adding to your xsl: xsl:template match=/ xsl:apply-templates select=document/ /xsl:template Doing those two things, it works fine. If that doesn't fix it, I'd reccomend: - Add the error page back in to your stripped down pipeline. - stop tomcat, while it's down delete your cache-dir (probably under $TOMCAT_HOME/work - the default). - monitor your access.log, and on startup core.log to confirm that things are starting and processing correctly without errors. (I often do tail -f access.log while testing pages in a browser in another window). Geoff Howard __ Do you Yahoo!?
