Hi All, I am trying to upgrade our existing xwiki implementation of version 3.1 to 3.4 and I am running into an error when attempting to start up the server. Environment: 1. OS: Redhat Linux 2. Container: Jboss 5.1 3. DB: Hypersonic At this point, I am just tying to get it to launch with the out-of-the-box configurations (no customization). Below is the stack dump I am receiving: 2012-01-27 10:45:52,759 INFO [org.jboss.web.tomcat.service.deployers.TomcatDeployment] (main) deploy, ctxPath=/xwiki 2012-01-27 10:45:53,146 ERROR [STDERR]
