If you need help and this information is not enough, you are invited to read the Cocoon FAQ.
If you still don't find the answers you need, can send a mail to the Cocoon mailing lists, remembering to:

• specify the version of Cocoon you're using, or we'll assume that you are talking about the latest released version;
• specify the platform-operating system-version-servlet container version;
• send any pertinent error message;
• send pertinent log snippets;
• send pertinent sitemap snippets;
• send pertinent parts of the page that give you problems.

For more detailed technical information, take a look at the log files in the log directory of Cocoon, which is placed by default in the WEB-INF/logs/ folder of your cocoon webapp context.
If the logs don't give you enough information, you might want to increase the log level by changing the Logging configuration which is by default the WEB-INF/logkit.xconf file.

If you think you found a bug, please report it to Apache Cocoon issue tracker; a message will automatically be sent to the developer mailing list and you'll be kept in contact automatically with the further progress on that bug.

Thanks, and sorry for the trouble if this is our fault.
