Hi Matthias, Did you comment out or removed by mistake the following line from your hibernate.cfg.xml? <mapping resource="activitystream.hbm.xml"/> Hope this helps, Marius On Tue, Dec 3, 2013 at 12:54 AM, Matthias Albert <matthias.albert@gmx.de> wrote:

After trying to import the standard XWiki-5.2.1 pages, I could not import all the default pages. The resulting error message counted ca. 10-20% of all pages as erroneous.

I could manage to import a small number aof pages (2-3).

I am using a MySQL database configuration.

In the Tomcat error log, the first and often repeated exception are copied after these lines.

Does anyone have a hint? Could it be a configuration problem?

Thankyou in advance Matthias
