Great. I think the following ticket is related. http://base.thep.lu.se/ticket/438 There is a bug in some MySQL version that gives an incorrect error message. The actual error seems to be that the encoding for the connection isn't compatible with the encoding used for the database. See MySQL section of http://base.thep.lu.se/chrome/site/doc/configure_unicode_support.txt for more information. /Nicklas > > Stack trace > > ...at HibernateUtil.commit(HibernateUtil.java:869) > ...at
