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?
Again as I
told you the ExecutionContext is properly initialized but
the XWikiContext is something else, the Provider among other things
create and set a XWikiContext when there is none. Now what is wrong is
that you end up in AbstractDataMigrationManager in your thread since
its supposed to be called only the first time a request is done.
When do you start your job exactly ? Are you sure the database is
ready when you do (it's not before the first access to the wi trough
the browser) ? You can listen to
org.xwiki.bridge.event.ApplicationReadyEvent to be notified when it's
ok to use the database.

http://lists.xwiki.org/mailman/listinfo/users 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:
