Kukeltje, I can open here the HSQL Database Manager and can see all tables created, everything is fine, all data are in the tables. The persistence works if I run my process from the jBPM Console. The data are being stored in the tables. The problem is if I try to instance a process from the eclipse, like I described. I receive the error "couldn't find process definition 'NameOfMyProcess'". I was using all default configurations that came in the hibernate.cfg.xml. Then I tryied to change the hibernate.cfg.xml. When I changed the hibernate.cfg.xml I received other error: "Could Not Find DataSource". The differences from the hibernate.cfg.xml file that I was using from the hibernate.cfg.cml file that I tried now (hibernate.cfg.xml that is inside the jbpm-console.war file) 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 that I tried now - 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. If someone have some idea, please, help me. I thank all, but I thing I will change the database to MS SQL Server. I hope that will work better than hypersonic.
