Mputz The structure of my application is correct, thank you. I tried to use the hibernate.cfg.xml that you said (jbpm-console.war) and tried to intance my process like the java code I posted above, but I receivied the error "Could not find datasource" But when I start the process from the jBPM Console, it works fine. The differences from the hibernate.cfg.xml file that I was using from the hibernate.cfg.cml file that I tried now (the file that you said) are the following lines: hibernate.cfg.xml that I was using - Receive the error: "couldn't find process definition NameofMyProcess'" | <!-- JDBC connection properties (begin) --> | <property name="hibernate.connection.driver_class">org.hsqldb.jdbcDriver</property> | <property name="hibernate.connection.url">jdbc:hsqldb:mem:jbpm</property> | <property name="hibernate.connection.username">sa</property> | <property name="hibernate.connection.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) --> Hibernate.cfg.xml file that I tried now (jbpm-console.war) - Receive the error "Could not find datasource": | <!-- JDBC connection properties (begin) === | <property name="hibernate.connection.driver_class">org.hsqldb.jdbcDriver</property> | <property name="hibernate.connection.url">jdbc:hsqldb:mem:jbpm</property> | <property name="hibernate.connection.username">sa</property> | <property name="hibernate.connection.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) --> | I just posted the differents lines between the two files, the other lines are the same for both files.
