Hello,
I'm trying to use the Job Module [1] for my own needs.
I know some of its APIs are marked as unstable, but well I wanted to give
it a try.
I'm on a XWiki 4.5.2 instance currently.
So I created some dummy interface:
@Role
public interface ILoadingJob extends Job
{
}
Job is already a @Role so I don't understand why override it with ILoadingJob.
A Job implementation:
@Component
@Named(LoadingJob.JOBTYPE)
public class LoadingJob extends AbstractJob<DefaultRequest> implements
ILoadingJob, Initializable
{
public static final String JOBTYPE = "mailarchivejob";
// ...
}
In debug mode, I run the following:
this.componentManager.getComponentDescriptorList(org.xwiki.job.Job.class)
It returns:
[implementation = [org.xwiki.contrib.mailarchive.internal.LoadingJob],
instantiation = [PER_LOOKUP], implementation =
[org.xwiki.extension.job.internal.UpgradePlanJob], ... ]
So it seems OK.
I have the following code to create and execute my Job:
DefaultRequest request = new DefaultRequest();
request.setId("test");
request.setInteractive(false);
// ... other properties set
LoadingJob job = (LoadingJob)
jobManager.executeJob("mailarchivejob", request);
But this code fails with following stack trace:
org.xwiki.job.JobException: Failed to lookup any Job for role hint
[mailarchivejob]

I also tried to manually register my custom Job component, in the
initialize() of a side component (I checked that this code got executed
previously to job creation), but with no different result:
// Register custom job
this.componentManager.registerComponent(this.componentManager.getComponentDescriptor(Job.class,
"mailarchivejob"));
Do you see something wrong in my approach ?
Thanks,
Jeremie
