Eventually I figure out that AbstractPublication.java's getTree()
method is where the sitetree.xml contents are cached, in the siteTrees
hash. And I discovered that if I change AbstractPublication.java so
that the "siteTrees.containsKey(area)" test (line 327 in my Lenya
1.2.4 version) is skipped then my problems go away (there should be a
performance cost in doing so, but it appears to be pretty small).
Strangely, I don't see anything in AbstractPublication.java that
*ever* invalidates the cache, which would be needed whenever a
document is created, moved, renamed, etc., so I don't see how it is
*ever* working, even for non-WebLogic deployments.
maybe Andreas has an answer to this ;-)
Am I not getting any feedback on this because the site tree mechanisms
are entirely different in 1.4?
I think it's quite different, whereas 1.4-dev is also using a
sitetree.xml, but AFAIK transactions are being
used and I cannot really tell about possible issues. From out of my
belly I would say, that everything which
doesn't load stuff incrementally (kind of AJAX style) will lead to
scalability problems, but that's another
discussion.
If so, I still think that the 1.2.4
documentation on the Lenya web site should have a lout disclaimer
about it not working well under WebLogic 8.x.
well, we once used WLS 8.x for a customer and we didn't experience these
kind of problems.
Other problems though.
Have you ever tried 1.2.5-dev version? Whereas the major bufixes memory
wise were part of the 1.2.4 release if
I remember correctly.

Subject: Re: sitetree out of synch
Hello Developers,
I didn't get an answer to this on the user list, and I'm still stuck,
so I thought I'd ask you really smart guys on the dev list...
The Lenya CMS is not seeing changes to my publication's site tree.
That is, when I do anything that would affect the sitetree.xml file
(e.g. moving a document up/down, changing the navigation title, or
creating or deleting a new document, the
lenya/pubs/{publication}/content/authoring/sitetree.xml file is being
changed correctly on disk but the web interface is *not* updating. The
site tree shown on the Site tab remains unchanged and out of date
until
I restart Lenya.
I think I understand how Cocoon caching works, and ultimately the
SiteTreeGenerator component defined in sitemap.xmap should be checking
the modification date of the sitetree.xml file, right?
I know this is not a browser caching issue because the date in the
upper right corner of the page always changes.
What could cause the site tree component in memory to not update?
Thanks for any help you can provide! I can't do much of anything with
Lenya unless I can resolve this.

Subject: Re: sitetree out of synch
A correction on my situation. Restarting my Lenya *does* put the Lenya
GUi back into synch with what is in sitetree.xml.
Restarting Lenya every time a new document is created isn't practical,
of course. So my question becomes: what would cause the Lenya GUI
(e.g., the Site tab) to not reflect what is in sitetree.xml?
Create, delete, move up/down, edit navigation title, all these have
the
same problem where the Lenya GUI is out of synch with changes made
correctly to sitetree.xml.
I'm running Lenya 1.2.4 under WebLogic 8.1 SP2 running behind an SSL
SunOne web server.

Subject: sitetree out of synch
Hello all!
When creating a new document in Lenya 1.2.4 (under WebLogic 8.1), the
page is created and the sitetree file (pubs/{my
pub}/content/authoring/sitetree.xml) is updated correctly on disk, but
apparently not in memory. Lenya's log file says:
4 2005-10-31 09:03:50,315 [ExecuteThread: '24' for queue:
'weblogic.kernel.Default'] ERROR
sitemap.handled-errors.prepareErrorHandler():165 - Document /test333
does not exist. Check sitetree, it might need to be reloaded.
org.apache.lenya.cms.publication.DocumentDoesNotExistException:
Document
/test333 does not exist. Check sitetree, it might need to be reloaded.
So, how do I reload the sitetree? I can't find it in the docs.
There are other signs that the sitetree is out of synch somehow. For
example, when deleting a document, the GUI appears to work normally,
and the document is removed from sitetree.xml, but the document still
appears in the "Site" tab in the Lenya GUI. Even after restarting
Lenya
the sitetree.xml on disk is out of synch with the GUI in this way. So
I
assume Cocoon is caching something. How do I clear the cache, if that
is likely to help?
