Hi,
I created a Macro in xwiki.
In this macro a server process is started that tries to read attachments.
For this, I created a XWikiCOntext to access the Wiki.
This is the code:
XWikiStubContextProvider
prov=Utils.getComponent(XWikiStubContextProvider.class);
prov.initialize(template);
XWikiContext con=prov.createStubContext();
con.setUser("XWiki.TestProcess", true);
con.setVirtual(true);
Unfortunately it is not possible to access the attachment content using
this context.
The following error is thrown:
com.xpn.xwiki.XWikiException: Error number 3231 in 3: Exception while
loading attachment myseedfile.dgn of document
microtest_oto.Templates_Test-Stefan
at
com.xpn.xwiki.store.XWikiHibernateAttachmentStore.loadAttachmentContent(XWikiHibernateAttachmentStore.java:233)
at
com.xpn.xwiki.doc.XWikiDocument.loadAttachmentContent(XWikiDocument.java:4600)
at
com.xpn.xwiki.doc.XWikiAttachment.getContentInputStream(XWikiAttachment.java:576)
at
org.centauron.xwiki.help.XWikiAttachmentCopy.doCommand(XWikiAttachmentCopy.java:79)
....
Any help would be appreciated.
Regards, Stefan.

Could you copy the complete error, you should have a more detailed cause.

Btw, you should take a look at the Job Module
http://extensions.xwiki.org/xwiki/bin/view/Extension/Job+Module which
provides a clean way to perform, in a background thread, tasks that
access the XWiki model.
Hope this helps,
Marius

Hi,
the Job Module looks promising,
however this is the stack:

That's probably because you don't properly initialize your thread
(initialize an ExecutionContext and stuff like this). You can use
org.xwiki.context.concurrent.ExecutionContextRunnable to help with
this. Also to get a proper XWikiContext it's usually better to use
Provider<XWikiContext> (either by injecting it or by using
XWikiContext#TYPE_PROVIDER as role type).
