[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.
