First, if you really want to use the datasource as defined in jbpm-ds.xml, you should alter hibernate.cfg.xml to resemble this: | <!-- DON'T USE DIRECT HIBERNATE CONFIGS, USE DATASOURCE INSTEAD --> | <!-- | <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property> | <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/jbpmbackend</property> | <property name="hibernate.connection.username">root</property> | <property name="hibernate.connection.password">password</property> | --> | <!-- JDBC connection properties (end) --> | <property name="hibernate.cache.provider_class">org.hibernate.cache.HashtableCacheProvider</property> | <!-- DataSource properties (begin) --> <property name="hibernate.connection.datasource">java:/JbpmDS</property> <!-- DataSource properties (end) --> Next, do you have users in your database? What does this SQL query return? SELECT PASSWORD_ FROM JBPM_ID_USER WHERE NAME_='manager' View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4135206#...
