cocampo! Unfortunately, This does not work! I have discovered, that I already do exacly what you have written. sessionFactory = (new Configuration()).configure("WEB-INF/hibernate-jtds.cfg.xml").buildSessionFactory(); This does not help, There is some difference between server logs, when JBPL deployed and when it was not deployed. And JBPM does somthing with JBoss-Hibernate configuration that redirect my actuall call to MSSQL to JBoss default data base... Could you or someone help?
