Hello again Moving on to XWiki 5.1 did the trick, except that I run into another trouble ... When my job is starting, I get a NPE: Exception in thread "Job Manager daemon thread" java.lang.NullPointerException at org.xwiki.job.internal.AbstractJob.jobStarting(AbstractJob.java:170) at org.xwiki.job.internal.AbstractJob.run(AbstractJob.java:134) at org.xwiki.job.internal.DefaultJobManager.runJob(DefaultJobManager.java:131) at org.xwiki.job.internal.DefaultJobManager.run(DefaultJobManager.java:110) at java.lang.Thread.run(Unknown Source) It's on following "this.logger..." line in AbstractJob: if (getStatus().getRequest().getId() != null) { this.logger.info("Starting job of type [{}] with identifier [{}]", getType(), getStatus().getRequest() .getId()); } else { I checked and getType() is not null. The other can't be. So could it be that this.logger is null ? Could it be again a pb of root component manager ? BR, Jeremie 2013/9/26 Jeremie BOUSQUET <[email protected]>
Oups... ;)
No I'm on 4.2, but I suppose I'll be on 5.x soon... Le 26 sept. 2013 18:52, "Thomas Mortagne" <[email protected]> a écrit :
addJob(Job job) not addJob(String jobType, Request request) ;)
But maybe you are not on 5.1 yet.

I added the line of code, that revealed a number of errors in my component. I fixed them, and now this getInstance(...) appropriately returns a LoadingJob object. I've put the code just before my code calling executeJob(). But even after these corrections, I still get the same issue on executeJob(). BTW, I have same problem when calling addJob().

Yes it is. As I'm currently using some SNAPSHOT version, I installed it once with EM (linked to a local nexus repository), and now I patch the jar under $XWIKI_DATA_DIR/data/extensions/repository/..., during server restart.
That's it then, I re-checked the DefaultJobManager and it only look at root component manager. Fixing it in 5.2RC1.
In the meantime you can use addJob(Job).
addJob(Job) has the same problem:
