[xwiki-users] Could not initialize main XWiki context - Xwiki 2.4

I recently switched to a new server and upgraded to the Xwiki Enterprise 2.4. I was able to get the installation working, but after an update to Tomcat6 from the Ubuntu repository, Xwiki stopped working. (I'm not completely sure that the tomcat update was the problem) I tried re-installing Xwiki using the same procedure as before (http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Installation#HInstallin…) but it still doesn't work. Tomcat works; at least the default test page. So, I then tried reinstalling tomcat6. Then I copied the previously expanded xwiki WAR contents back into webapps. Same thing. Tomcat appears to work just fine, but xwiki crashes. Details about my setup: Running Ubuntu 64-bit Lucid Lynx 10.04 Tomcat6.0.24 MySQL 5.1.41-3ubuntu12.6 (Ubuntu) The error seems to be complaining about my hibernate file. I have tried following the instructions from the link above by just editing the xml to match to lines in the instructions. I have also tried uncommenting the setup for MySQL in the hibernate file. Both ways produce the same results. Can anyone help, please? I'm pretty desperate. Thanks, travis Here is my hibernate file: <?xml version='1.0' encoding='utf-8'?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <!-- Please refer to the installation guide on http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Installation for configuring your database.
