Hi Ludovic!
Please let's start with mysql first .. It does not make sense to debug both things at a time.
sure :) Now I have installed two instances of xwiki - one for mysql, second for pgsql. both look and act identically.
The "cannot execute query" is not enough.. It should show a wrapped exception but for some reason it doesn't. Can you try with the What's New or WebSearch page ?
Sure! I have attached both exceptions along with full server log... (btw. hale to bzip2 that packed all this from ~3MB to only 46kB! I hope nobody will kill me for this attachment)
Can you also turn on debugging in log4j.properties so that you see if hibernate generates a query..
### Hibernate logging options ### log4j.logger.org.hibernate.SQL=debug log4j.logger.org.hibernate=debug log4j.logger.org.hibernate.type=debug log4j.logger.org.hibernate.ps.PreparedStatementCache=warn is it ok? Thank You! Tomek
