Yes, i read that thread till the end but didn't tried MySql. I tried H2 to be sure if it's database related issue but same stack trace. I am planning to use that wiki in our server environment. We use weblogic as application server and Oracle11g as database server. Actually, after i test standalone version in my desktop, i tried to deploy xwiki to weblogic and had several errors. I passed all of them and stucked at this one. After that i gave a try to Apache Tomcat and same issue. I am trying to make it work for a week but i am desperate now. I think, i will use standalone version at the production environment :)
