Re: Quartz Job setup with JobDetails requires parameter free constructor - how to inject Service bindings

[Kalle Korhonen <ka...@gmail.com>]

You create a JobSchedulingBundle (service), create a JobDataMap in it,
add all the services to the map you need in your Job and then then get
the map via executionContext.getMergedJobDataMap(). The concept behind
JobDataMap is solid but you could arguably make a tighter and
easier-to-use Tapestry-specific integration for Quartz. I'd love to be
able to do just:
configuration.add("0 0 0 * * ?", myJob);

But I'm too lazy/busy to work on it myself since even the current
Chenillekit-provided integration works fine with the expense of a few
redundant lines of code.
