Re: Job Scheduler in Lenya/Cocoon

[Florent André <fl...@4sengines.com>]

Hi all,

The return of cron bug ! :) (resume of lasts episodes : the cron job in
cocoon.xconf don't work on Lenya 2.0)

As Anish said : "it's work for me on Lenya on Lenya 1.2.4",
-- I do a diff on the org.apache.cocoon.components.cron.CronJob of 1.2 and
2.0 : there is some diff.
-- so I get the 1.2 CronJob.java, compile it as
CronJobOld.java, try it in the cocoon.xconf cron definition... and it's
don't work...
-- So the idea of a problem in the global-sitemap.xmap seems to be good...

BUT : as Andreas suggests, fire the pipeline throw browser work
- so, I edit my linux crontab with this line : 0 9 * * mon wget -O
/dev/null http://tomcat.serveur/lenya/dev/modules/mymodules/mypipeline
- and it don't work
- I open a fresh lovely firefox on the pipe... and it don't work !
- I open a new tab and CONNECT to Lenya, I refresh my pipe's tab : and it
work !

IN FACT :
- the call of this pipeline works when we are CONNECTED to lenya
- the cocoon.xconf, and a unconnected browser can't fire the pipeline !

QUESTIONS :
- Anish, can you redo this "way of work" ? (pipeline fire when connected,
but not when not connected)
- In my case, the module's resource is on authoring (have to be connect)...
but I fire a pipeline that have no deal with this resource. I think that
there is no relationship between the publication status of the resource and
the possibility of fire a pipeline. I'm right ?
- This possible to define a pipeline that we can call without have to be
connected ? 
- In a more general way, what is the relationship between pipeline and
connexion ?

Thanks !
Have a good day
