Exception in DBCPConnectionProvider

[Arnaud Thimel]

Hi,

Yesterday I updated my XWiki from SVN.

I have a project working on it, and with the latest XWiki, I can't
launch my project.

It seems that there's an issue with my database because I can launch the
standalone XWiki, it works fine. But as soon as I plug it to my
database, I got the following exception. (XWiki.XWikiPreferences is just
an exemple, I got this exception for each document)

This is very odd because my database was working fine until now !

In the source code, it sounds like my "BasicDataSource ds" in
DBCPConnectionProvider.java is null. So I guess it comes from my
configuration, then i tried to check my hibernate.cfg.xml, but all seems
fine.

Does anyone has an idea ?

    Arno.
