Inside jbpm-configuration.jar are jbpm.hibernate.cfg.xml and jbpm.cfg.xml files. I tried adding to .jar file another hibernate.cfg.xml with the same content of the jbpm.hibernate.cfg.xml, but new error appears: 18:58:55,495 ERROR [[/jbpm-bpel]] Exception sending context initialized event to listener instance of class org.jbpm.bpel.web.JbpmConfigurationLoader java.lang.ExceptionInInitializerError at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:39) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:27) . . . .
