Hi there,
I already asked some questions about this on the users list. What I want to do: Inside my webapp I would like to create an action or something like an action to call Cocoon in CLI-style. Simplest way would be calling the "cocoon cli" script but that's to ugly... So my next approach was trying to use the CocoonBean inside of an action. I know this creates a complete second instance of Cocoon but that seems more acceptable to me than the "external-execute" approach.
Some basic infos: I'm using Cocoon 2.1.3 / Sun JVM 1.4.1 / Win2000 and Tomcat 4.1.24 as servlet container. Cocoon was compiled as webapp.
I wrote some test code and played a bit and create a publish() method based on code in org.apache.cocoon.Main which sets up a CocoonBean and exports some Uris...
Using the java code (below) it's possible to call the publish() method
from the main() method or as action inside of Cocoon. It's setting up a CocoonBean and exporting 2 URIs defined in my sitemap.
Calling publish() through main() from CLI works like expected but calling the action from the sitemap fails with this message:
BROKEN: Environment stack has not been cleaned up properly. Please report this (if possible together with a test case) to the Cocoon developers.
Maybe it's related to 'abuse' of CocoonBean in my code? :) Maybe someone can help me getting this topic clearer...
- it it possible to run to instances of Coccon in the same JVM? - is there something missing in my CocoonBean setup that causes the message above that can be fixed? - is there a better way to use Cocoon CLI from a Cocoon webapp?
Thanks, Patrick
