It depends what's your situation. This error generally mean that you don't have xwiki-commons-logging-logback jar in your classpath. On Tue, Mar 13, 2012 at 12:26 AM, Paul Libbrecht <paul(a)hoplahup.net> wrote: -- Thomas Mortagne

I don't know any QueryExecutor with this hint, there is only "hql" and "xwql" which are the supported query languages. "hibernate" does not make much sense at this level. Probably some code which wrongly use "hibernate" instead of "hql". -- Thomas Mortagne

Both are there. Among the helpers, I found that comparing to a working 3.3 was useful (and using help:effective-pom on a checkout). I see no difference (except s/3.3/3.5).
