And to do that I changed the Id as you said, and also I changed the configuration file of hibernate in the target folder. Before, I had only copied the same configuration file of hibernate from the target folder of examples, but I am using MySQL DB not HSQL one, so I must configer jbpm to use that DB. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/532753#532753
