Hi Ricardo,
We realized, after the release of XWiki 7.0 that due to our upgrade of DBCP to version 2.1
we’ve introduced a new requirement: JDBC 4 (I’m not sure if we require JDBC 4.0 or 4.1
actually, still trying to find out).
See
http://www.xwiki.org/xwiki/bin/view/ReleaseNotes/ReleaseNotesXWiki70#HIssue…
(http://www.xwiki.org/xwiki/bin/view/ReleaseNotes/ReleaseNotesXWiki70#HIssue…)
(http://www.xwiki.org/xwiki/bin/view/ReleaseNotes/ReleaseNotesXWiki70#HIssue…)
That said it seems that MySQL JDBC drivers 5.0.x are supposed to be JDBC4 compliant and
version 5.1.x certainly are too.
Thomas has just tested XWiki 7.0 on MySQL with version 5.1.28 and it was working fine for
him.
The error you get is strange. ATM I don’t understand it. We’re going to do more tests on
various DBs to see whether we need to rollback the DBCP upgrade or not.
Stay tuned.
Sorry about the problem
Thanks
-Vincent

Hi all!
We have successfuly updated our XWiki 6.x installation along the whole 6 cycle, but
I'm in troubles with the new 7.0 release. I think that with only the first four lines
of the error stack
XWiki initialization failed !

Well, this piece is a good candidate for being identified as the poblem, but updating it
to the last available release...
mysql-connector-java-5.1.35-bin.jar (2015-03-23)
...doesn't solve the issue.
As they are a lot of versions between mysql-connector-java-5.0.8-bin.jar (working for us
nicely so far) and the newest mysql-connector-java-5.1.35-bin.jar (failing for us, at
least with this combination of Java, Tomcat and MySQL), please, could you tell us if we
are in the right direction? Should we update any other component but
mysql-connector-java-x.y.z-bin.jar to get XWiki 7.0 working? Should we start trying one by
one mysql-connector-java-x.y.z-bin.jar newer releases? Do you know which release
introduces JDBC 4.1 support?
Thanks you so much for your help!
Ricardo
