Subject "Scheduler with name 'Cocoon' already exists."
Date Wed, 05 Jan 2005 19:39:37 GMT
Hi all,
We're trying to run two instances of Cocoon side-by-side under Tomcat 4.1.
The first one, Cocoon 2.1.2, is the default context (path="" in Tomcat's 
server.xml file). It works fine, giving a welcome page for the URL 

The second is one we just added. It's Cocoon 2.1.6. We added a context 
for it at path="/cocoon-2.1.6", with its own docBase.
After restarting Tomcat, when we try to connect to second instance 
through the URL http://server/cocoon-2.1.6/, we get this error in the 

  Initialization Problem

Message: Scheduler with name 'Cocoon' already exists.

org.apache.avalon.framework.configuration.ConfigurationException: cannot 
create a quartz scheduler

Sender: org.apache.cocoon.servlet.CocoonServlet

Source: Cocoon Servlet


org.quartz.SchedulerException: Scheduler with name 'Cocoon' already exists.

Any idea why?
We are running parallel instances of Cocoon under Tomcat on another 
machine, and not having this problem. As with the above, one has an 
empty string for the context path; the other has a nonempty string.
The other machine uses different versions though -- Tomcat 5.*, and 
Cocoon 2.1.2 for both Cocoon instances.

I saw the following thread:
which appears to address this issue, but the suggested solution seems to 
relate only to the Sun Java System Application Server as far as I could 

Thanks for any help.
