Thomas,
it seems it has nothing to do with my context.
I tried to initialize my context with the xcontextProvider. It failed again.
Instead I checked the source code of
AbstractDataMigrationManager.getXWikiContext which is shown in the stack
trace and it found this:
protected XWikiContext getXWikiContext()
{
ExecutionContext context = execution.getContext();
return (XWikiContext) context.getProperty("xwikicontext");
}
Seems that the Context is not injected properly when it runs in a job?

Thomas,
thanks. I managed to build my thread as an XWiki Job and also managed to add
it to the JobExecutor.
However, my initial problem still persists.
I am not able to add an attachment to a document in this job.
Find the stack trace below. Looking at the source of XWikiHibernateBaseStore
tells me, it has something to do with the Execution context of the Job, but
this should be managed by the job executor, right?
This is my code snip to add the attachment:
XWikiContext mycon = (XWikiContext)
execution.getContext().getProperty("xwikicontext");
The ExecutionContext is initialized automatically but XWikiContext is
something else and you should never try to get it directly from the
ExecutionContext but use the provider instead as in:
@Inject
private Provider<XWikiContext> xcontextProvider;
XWikiDocument doc=mycon.getWiki().getDocument(m_adoc, mycon);
XWikiAttachment att=doc.getAttachment(m_file);
if (att!=null) {
doc.deleteAttachment(att,mycon);
att=null;
}
if (att==null) {
att=doc.addAttachment(m_file,ins ,mycon);
XWikiAttachmentStoreInterface
ai=doc.getAttachmentStore(mycon);
XWikiHibernateAttachmentStore
hib=(XWikiHibernateAttachmentStore)ai;
hib.beginTransaction(mycon);
ai.saveAttachmentContent(att, mycon, true);
hib.endTransaction(mycon,true);
att.updateContentArchive(mycon);
}
This is the stack trace:

Everything in XWiki is based on JobExecutor now so I can assure you it
does not wait. Maybe your job is doing something slow in initialize.

Thomas,
if I start a job using
jobExecutor.execute("antjob", req);
it waits until the job is finished.

As indicated in the javadoc of JobExecutor all jobs are executed
asychronously. You actually need to use Job#join when you want to
wait.

Hi,
I have seen that the jobManager is deprecated since 6.1.
But how would I schedule a job and return immediately using the
jobExecutor?
(Using the jobManager it would be something like :
Job job = jobManager.addJob("jobtype", request))
Thanks , Stefan.
