Hello Maciej,
thank you very much for your reply. I managed to find persistence.xml using your suggestion. One last thing: under jbpm-gwt-console-server-war/WEB-INF/classes/META-INF there is both hibernate.cfg.xml and persistence.xml. Do I have to replicate the connection settings in hibernate.cfg.xml or it's just necessary to use persistence.xml ?
Thanks a lot
