@Anders, apparently you have a configuration where the server is trying to establish a connection to the db defined by the 'jbpmDS' datasource. This only works inside JBoss, but not if you are deploying to a standalone Tomcat instance. In hibernate.cfg.xml, delete this <property name="hibernate.connection.datasource">java:/JbpmDS</property> and instead use a configuration similar to this: <!-- JDBC connection properties (begin) --> | <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property> | <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/jbpm32</property> | <property name="hibernate.connection.username">jbossjbpm</property> | <property name="hibernate.connection.password">jbossjbpm</property> | <!-- JDBC connection properties (end) --> See also: http://wiki.jboss.org/wiki/Wiki.jsp?page=JbpmOnTomcat Regards, Martin View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4044237#...
