What's causing the error "Could not find component (key [daisy-repository-manager])"?

[ This article applies from Daisy version any to version any ]

When browsing to the Daisy Wiki, you see the following error:

Initialization Problem

Message: null

Description: No details available.

Sender: org.apache.cocoon.servlet.CocoonServlet

Source: Cocoon Servlet

cause

Could not find component (key [daisy-repository-manager])

request-uri

/daisy/<something>

This error occurs when the initialisation of the "daisy-repository-manager" component fails, and the most likely cause of this is that it cannot connect to the Daisy repository server (full details can always be found in the log file: <wikidata dir>/logs/cocoon.log).

Possible reasons why the Wiki can't connect to the repository server:

the repository server is not running. Solution: start it, and also restart the Daisy Wiki. If you can't start the repository, the log files are the best place to start (please include the relevant contents of the log files if you contact the mailing list).
the repository server is running, but the Daisy Wiki was started too soon after it, when the repository was not yet fully started (takes at most a few seconds). Solution: restart the Daisy Wiki.
ActiveMQ login credentials do not match between Wiki and repository: edit the respective configuration files to make them match: <repodatadir>/conf/users.properties and <wikidatadir>/daisy.xconf (look for element credentials inside jmsConnection)
