Re: [jetty-dev] Jetty 8.1.12 and 8.1.13 fail to start Apache Cocoon 2.1.12
File a bug. https://bugs.eclipse.org/bugs/enter_bug.cgi?product=Jetty&format=guided
Attach the war that is causing problems.

The directions you provided to build cocoon do not work.
Results -> http://paste2.org/PgNn6dph

From a look at the source of 
org.apache.cocoon.components.source.impl.ContextSourceFactory.getSource(ContextSourceFactory.java:119)

https://github.com/apache/cocoon/blob/BRANCH_2_1_X/src/java/org/apache/cocoon/components/source/impl/ContextSourceFactory.java#L83-L127

You'll see that it attempts obtain a URL reference by calling

CoocoonContext.getRealPath("/sitemap.xmap")

Then either load the resulting URL as a File, or then
try to obtain a URL reference by calling

CocoonContext.getResource("/sitemap.xmap")

Interestingly, this process was changed with cocoon 2.2, which now just uses the javax.servlet.ServletContext itself.
https://github.com/apache/cocoon/blob/trunk/core/cocoon-pipeline/cocoon-pipeline-components/src/main/java/org/apache/cocoon/components/source/impl/ContextSourceFactory.java#L105

Have you tried Cocoon 2.2?

Greetings,

I have a problem starting up Apache Cocoon 2.1.12 framework with Jetty 8.1.12 and 8.1.13. It starts up just fine in Jetty 8.1.11 and 9.0.6, so I assume it is something about one of the changes done to .12 and .13 that breaks the startup.
I'm trying to start it up in Ubuntu 12.04.3 with latest updates; java version doesn't seem to affect this problem, since I tried both Oracle Java 7 as well as relevant OpenJDK version (and also versions 6 for 8.1.12/13).

I posted an error stacktrace from Cocoon's startup log[1], which seems to point at Apache's Excalibur component; sadly, I have little knowledge about what it does (or Cocoon's startup process to start with).

This problem is fairly easy to reproduce:
0) Download Jetty 8.1.12 or Jetty 8.1.13
1) Download Apache Cocoon 2.1.12 (you'll need both source and deps): http://cocoon.apache.org/mirror.cgi
2) Extract downloaded archives (both contain 'cocoon-2.1.12' folder, but they don't interfere with each other in any way), go to extracted directory and build cocoon (to speed things up a bit, you can build minimal cocoon by copying blocks.properties file to local.blocks.properties, and uncommenting in that one "exclude.all.blocks=true")
3) Copy the resulting webapp folder from build/ folder to Jetty's webapps.
4) Start up Jetty, after navigate to root page of Cocoon's webapp (for instance 'localhost:8080/webapp'), observe an error message.
  * The log file will be in webapp/WEB-INF/logs/cocoon.log file, unless you changed it in logkit.xconf)
5) Try the same with Jetty 8.1.11 or Jetty 9.0.6: instead of an error message, you will see Cocoon's welcome page.

Do you think it might be a bug/misfeature in current Jetty 8.1 version? Should I file a bugreport to Eclipse? Anything else I should try?
If you think this is most likely a problem in Cocoon itself, I could also post this problem to their mailing list.

Thanks in advance,
Alex-
