Lenya 2.0 questions
Hi,
we try to get used with lenya 2.0 and its concepts and have some questions.
We would like to have a scheduler, that from time to time imports some date
into the CMS.
How is this possible?
Additionally, we would like to export static XHTML onto a named drive.
This should also be triggered by a scheduler.
How does the tasks concept work in 2.0?
Could this be done with Lenya 2.0?
We could not find some helpfull information in the wiki.
What would be a good place to start?
Thanks in advance!

BTW, for the actual import you could start with examining the test case
in the export module.

Option A:
Use a (Unix) cronjob which starts a module test case.
Option B:
Extend the usecase scheduler [1] to handle recurring jobs. This should
be no problem, IIRC the Cocoon scheduler allows to schedule recurring jobs.
Option C:
Use the Cocoon cron block directly.

The easiest way would be a cronjob which starts wget. You could also do
this in Java, but I'd rather use existing tools.

It has been replaced by the usecase framework:
http://lenya.apache.org/docs/2_0_x/reference/usecase-framework/index.html
> Could this be done with Lenya 2.0?
Yes, but the OS tools might be the better option in these cases.

That's no problem if you're familiar with Java development.

Same here.

Yes, the Cocoon cron block uses the Quartz scheduler. Lenya's usecase
scheduler uses the Cocoon cron block.

The presentation options are entirely up to you.

For this purpose you could extend e.g. the Publish usecase to export the
generated documents to the file system.

That depends on your requirements. It's a proven, robust approach which
requires no implementation and virtually no configuration. If you want
to configure it via the CMS GUI, you have to invest some time.

Thanks so far for the answer, even its not what I wanted to hear :-)
OK, lets get more specific.
I would like to do something like content syndication and therefore I'm
looking for an easy to use open source CMS.
We want to to create some basic importers, like html, xhtml, http, xml,
which read data from different sources and stored the content as XML in a
repository (which could e.g. be Lenya).
The content then gets enriched manuelly with some attributes and then it
should be automatically be exported into the file system in a different
format (mostly (x)html.
Additionallys the system should create some javascript files, based on the
properties which are attached to the content. The content should be version
controlled.
I thought Lenya maybe has something like a QuartsScheduler included?!?!
What i NOT want is a complete web page to be created with navigation and
links like this. More or less just some HTML fragments for later reuse.
For performance reasons I would prefer that the content is directly
accessible through the file system with no tomcat or jetty in between.
The wget solutions sounds feasable but not very elegant.
Thanks for your support.

it should be possible with the import usecase, but you would need to be
more specific...

iiuc it has been thrown out.

for a quick yet effective solution to your export issue, just use a UNIX
cron job that uses wget:
*/30 * * * * cd /where/you/want/the/data; wget -l5 -r -q
http://yourdomain.foo/yourpage
i'm sure someone else can suggest a more elegant (if more complicated)
solution using the lenya api.
best,
jörn
