It seems like the xml configurations didn't been read by the hibernate. These NamedQuery had been defined in the jbpm.execution.hbm.xml , jbpm.execution.hbm.xml. By default, the jbpm.jar or jbpm-pvm.jar will contain these xml configuration. Could you recheck whether these dependencies were copied to tomcat?
Hi HuiSheng. I'm using 4.4, I could find the jbpm.jar on both the jbmp lib directory and the tomcat directory. I could not find the jbpm-pvn.jar.
