Using Quartz for sending emails
mattcole
I think this will demonstrate my very novice level of understanding of
Quartz .Net, but I'm wondering if I can use the inbuilt send email job
to send emails for my application.
That obviously shouldn't be a problem, I think the problem revolves
around my lack of understanding of jobs and triggers. I have a custom
job that is set up to run each day and it checks a db table for some
information and if any is found it needs to send some emails. I was
hoping I might be able to schedule or trigger a SendMailJob from
inside my job.
What's the best way to go about doing this? I really just want to
create a job that is triggered instantly then disappears. Is this a
bit of a misuse of Quartz? I've written code along the lines of:
var job = new JobDetail("emailJob", "global", typeof (SendMailJob));
job.Durable = false;
// put some stuff in jobdatamap
scheduler.ScheduleJob(job,
TriggerUtils.MakeImmediateTrigger
("sendEmail", 0, new TimeSpan(0)));
This throws an error telling me that "Unable to store Job with name:
'emailJob' and group: 'global', because one already exists with this
identification". I assume as I haven't created a job with that name
and group in my quartz_jobs.xml file this means that the job created
the last time this code ran is still in the scheduler.
I tried to instead define a generic job in the quartz_jobs.xml file,
and then trigger it, but it seems to try and create an instance of the
job despite the absence of a trigger and then throws an exception as
I'm not providing it with its required configuration (email message,
sender etc).
I get the feeling I'm going around this the wrong way entirely, does
anyone have any ideas of how best to do something like this?
Thanks,
Matt
