Scheduled Jobs
Hi!
In my struts app I have to do some cleanup jobs in my database that I
like to start regularly. What's the best way to realize such schedules
jobs in a struts app?
Thanks in advance.

On the windoze side, you can use Scheduled Tasks.

Personally, I'd use cron. If you're not on a Un*x box then that's not
an option - I would think Windoze would provide something analagous
though ...
The process cron kicks off could be any executable file, so you aren't
even tied to doing it in Java. For my $0.02, you could probably whip
together a simple Perl script that did what you needed, and save some
overhead.

Hi,
you may define some thread to be started while the app init process.
Works nicely for us.
Two classes are required.
1. Simple init servlet that will be plugged into web.xml
(similar to the way that struts action servlet is plugged)
In the 'init' method you could start your thread daemon.
You could also pass some parameters this way.
Stop the thread in the 'destroy' method.
Because this solution works with threads, I would advise to
put some flag there if it has already been started or not, to make
sure there is only 1 instance of your thread.
2. The thread class.
It could be parametrized (see above), for example JNDI resource
name for database, interval, etc ...
We sceptic about such solution, but it really works nicely when we
tried it.
Another solution.
You could create some servlet that does cleanup job,
and periodically call it with cron.
I would advise 'curl' as your http client - works on Unixes and
Windows. It's very nice, free, single file program.
That solution is platform dependent, ie. different way of configuring
cron, and different versions of your http client are required.
Is anybody using different solution?
