I just did that, running on Tomcat 5.5 against a MySQL
5.0.21 server.
I loaded the database dump from the old xwiki app.
Unfortunately, still the same error, see below.
I use MySQL 5.0.22 and it works
great.
I think XWiki might have a problem with porting from the old xwiki with
Postgres and not the JDBC driver or the Hibernate thing.
