Hi salaboy, Thank you very much for your response. I am using jbpm-jpdl-3.2.2 and I created the jbpm database with the script mysql.create.sql from jbpm-starters-kit-3.1.4 And then I ran jbpm.jpdl.mysql.sql from jbpm-jpdl-3.2.2. But I see that Timer table is not changed with jbpm.jpdl.mysql.sql and so it is not coincide with Timer.hbm.xml from jbpm-jpdl.jar. Thank you very much once again and I need to know how to create the database correctly. Regards, Victor View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4143000#...
