Hello, I followed Ludovic Dubost his Oracle Installation notes. I think that he missed a modification to the xwiki.cfg. In there the xwiki.store.hibernate.path points to the /WEB-INF/hibernate.cfg.hsql.xml instead of /WEB-INF/hibernate.cfg.xml. I installed it on Oracle Database 10g Enterprise Edition Release 10.2.0.3.0. It seems to work without a problem. Then I also have a question. Can you define a different port for the Email server? We do not use port 25 and therefor we can not use the Email notification. Regards, Marco
