RE: Quartz Job setup with JobDetails requires parameter free constructor - how to inject Service bindings
It's still a WIP but I created a TapestryJobCreator which gets a
PerthreadManager and a Runnable (your service) in the JobDataMap. This just
calls run() on the service and does any cleanup. I need to tidy up the job
creation part but you could easily get to the point where you had something
like:
public static void contributeSchedulerService(ConfigurationJobInfo
config, MyService service) {
config.add(new JobInfo(0 0/30 * * * ?, service));
}
(where MyService implements Runnable and JobInfo is just a simple DTO)
Here is the TapestryJobCreator...
public class TapestryJobCreator implements Job {
private static final Logger
logger=LoggerFactory.getLogger(TapestryJobCreator.class);
public void execute(JobExecutionContext context)
throws JobExecutionException {
logger.info(Executing job);
PerthreadManager perthreadManager = (PerthreadManager) context
.getJobDetail().getJobDataMap().get(perThreadManager);
Runnable runner = (Runnable) context
.getJobDetail().getJobDataMap().get(runner);
try {
runner.run();
} finally {
logger.info(Doing cleanup);
perthreadManager.cleanup();
}
}
}
Hope it helps,
Alfie.

Subject: Quartz Job setup with JobDetails requires parameter free constructor -
how to inject Service bindings
Hi there,
I am using chenillekit-quartz integration and followed the example setup
on the module homepage
(http://chenillekit.codehaus.org/chenillekit-quartz/index.html). All
good so far, got things up and running. But now I want to run a job that
has other services (DAO, MailService) as dependencies. Setup is done via
JobDetails class which uses a parameter free constructor to instantiate
the implementation of an Interface:
new JobDetail(MailSenderJob, null, MailSenderJob.class)
I tried binding that clas (MailSenderJob) with build method in
Application module and @Inject annotation, but nothing did work, always
getting a NullpointerException when it comes to that service. I also
could not find a JobDetail constructor that allows for setting
dependencies, but no luck.
How can I get the service dependencies in MailSenderJob set up since
Quartz does only use default constructor?
Thankful for any hints
Daniel

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