I think this could be a bug. On my first try I used a MSSQL 2008 Server and I got this exception. Now I also tried on a MSSQL 2005 Server, the same result. But on this server I already have a running XWIKI but an old version. Can someone confirm that?

I already successfully installed this combination with an older version of xwiki. But however when I try to import the XAR File into XWiki I always get the following error in german: Importiere xwiki-enterprise-wiki-2.2.5.xar: Fehler während der Vorbereitung des Imports Translated into English this would mean about: There has been an error during the preparation of the import. What is the reason for that, is it possible that the XAR file on the xwiki website may be corrupted? Or is this a MSSQL problem. Please help me!

Hi Florian, Florian Rhomberg wrote: It's hard to tell the reason without a stack trace of the exception that occurs when you try to import the XAR. Look in the xwiki/tomcat logs. The XAR file is in fact a ZIP archive so you can rename and unzip it to see if it is corrupted or not. Hope this helps, Marius
