Cron Tutorial
Smola
platform. Google Wave is a very specific platform and there isn't
much documentation on it (crons with Wave). In the Java API tutorial,
cron jobs are mentioned as being available, but that's all I could
find on them. I have seen some other posts about cron jobs in groups
here and gathered that some lines of code should be added to the
capabilities.xml but I don't know the extent of the attributes I can
use or even how to use the ones I saw in the post (i think there was a
directory for a script? and then a time given that appeared to be an
interval like every 10 seconds).
So my question is this: Is there some documentation I have missed in
terms of cron jobs with wave (for the Java API)? If not, could
someone give a quick run down of their understanding of how this could
be used?
I am also aware that a mechanism is being developed that could replace
the need for cron jobs but I'd still like to familiarize myself with
the cron capabilities. Thanks for your time!

so cron works again? Last time I checked, my bot was never notified
and all
threads here spoke of cron not working for now (possibly until the new
mechanism
is rolled out).

The reference to Stocky, is for education/documentation only,
correct ?
I have read other messages which says that cron does not work at the
moment.
I have tried to do the same as Stocky, but it seems the cron does not
fire.
Also, any idea when the new cron environment is going to be rolled
out ?
Thanks,
Richard

Have there been any updates on the cron front in the last couple of
months? I'm also interested in using it but ran into the same problem
Smola did--no docs. I'll try to hack up Stocky if that's our best
resource, but if the new cron system was close to being completed
maybe it would be better to go that route.
Thanks!

I've gone ahead and tried to use Stocky's sample code to get Wave to
regularly check back with my robot for updates, but it doesn't seem to
be working. I think I've got everything all set up to log a simple
test message to the AppEngine logs every time Wave connects to my cron
servlet, but I'm not seeing any logs appear. You can see my
capabilities file here:
http://bastion-rm-mgr.appspot.com/_wave/capabilities.xml
and you can see that there's a RobotServlet running at the URL
referenced in the capabilities file (because it sends
a "GET not supported" error message if you type the URL in your
browser:
http://bastion-rm-mgr.appspot.com/_wave/robot/cronUpdate
But I'm only seeing logs print out from my servlet listening on the "/
_wave/robot/jsonrpc" URL, not the cron URL. It looks like the cron
heartbeat isn't firing. Any ideas?
Thanks!
