Good to know.
I just didn't see any code in the repository. ;)

chenillkit has a ready quartz module.
it works for two of my customers.
the only snag is the outstanding documentation.
i hope that i find some minutes to do that this week

you could use a dispatcher instead of a request filter, inserted
after the
asset dispatcher.
That way, only non-asset requests trigger the db update.
You could adapt your filter to only fire the update on non-asset
requests
by explicitly checking the url (for matching patterns, for instance:
^.*\.png$ and so forth).
You could have a separate thread that does the update. Then you
have a
service (which, naturally, will have to be threadsafe) that your
request
filter calls into to record all of the updates (multiple updates
from the
same user within the given timespan could be consolidated into a
single
update). The separate thread asks this service for the pool of
changes on a
regular basis (Quartz package would be useful here) and commits them.
There are other ways you could accomplish this, as well.
If you're interested in using a Quartz-based solution, it looks like
chenillekit is planning on adding it at some point (they have a
quartz
module, but it doesn't look like there's actually any code in there
yet).
Alternatively, I wrote an integration module for TapestryQuartz
that you're
welcome to use (contact me off list). I'll be releasing it for
general use
at some point, but I need to refine the documentation for it.

Thank you very much for the answer. Works perfectly!
But this brought up a new question. The UserActivityFilter is used
to
track
a users last activity to check for "active users at the moment". The
simplistic approach I use at the moment updates a database table
with a
reference to user and a timestamp. Using a requestfilter then
obviously
leads to a lot of database roundtrips per user-activity, since
every asset
triggers the filter.
How would you track useractivity in a real world application? A
resolution
of about 1 minute would suffice, but it shouldn't be much above
that.
