[xwiki-users] Not able to read attachments from server thread
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. On Wed, Nov 12, 2014 at 11:39 AM, Stefan Bernsdorf <gruener.heinrich@web.de> wrote:

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 On Wed, Nov 12, 2014 at 2:45 PM, Thomas Mortagne <thomas.mortagne@xwiki.com> wrote:

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).
