Within NetBeans? No idea. (As stated before, I don't
Are you able to advise how this may be done within NetBeans 6.9.1 / Tomcat
6.0.26?
Thanks.

Which means Quartz
Well, I've tried Mark's code earlier, albeit without using a properties file
for Log4J, and the position has
improved slightly.
The log indicates the following:

Thanks Mark. I will give this a try later on.

Once again, I apologize for the wall of text. However, most of it is
pretty quick and dirty code, so it should be easy to skim.
I'm guessing the end result is harmless?
It does seem like a race condition. Everything seems to work fine
until shutdown. When DEBUG is set in logging, you get the foll
ting the SchedulerFactory first, then getting a
scheduler, then starting the scheduler, and finally adding a job.

That is certainly possible. There was a reason I wrote the message "This
he scheduler should end 'gracefully' by
unsubmitting the jobs and by using scheduler.shutdown(true);.
If I'm wrong, please let me know.

You're probably correct and assuming this is to do with Quartz which it seems

Well, I've upgraded to Quartz 1.8.3 and the two SLF4J files that seem to be
needed. I believe Quartz's config is correct with regards to the two scheduled
jobs I have. But upon terminating my web app in Tomcat or terminating Tomcat, I
still find a number of messages:

Hello
I wonder if anyone can help here? I am developing a web application written
in Java servlets and JSPs which uses Quartz 1.6.1 to submit two jobs when
Apache Tomcat 6.0.26 is started and hourly after that.
But what I'm finding is that a message is issued several times as the server
is star
31 matches
