[rules-users] Problem in starting a new Process instance in Drools

I have configured correctly Drools and I could start the web console. But when I press on the process Instance and press start process I am having the following exception. Please can anyone help in this topic. Regards. The exception is: 15:57:32,359 ERROR [STDERR] java.lang.IllegalArgumentException: Unknown entity: org.drools.persistence.processinstance.ProcessInstanceInfo 15:57:32,359 ERROR [STDERR] at
