    This is not even a question.

    What are you trying to do when you get this exception? Can you share your configurations and the jBPM version that you are using?
    Cheers

    5.3.0.Final

     

    when I do so:

     

    KnowledgeBase kbase = readKnowledgeBase(url);

            // 创建EntityManagerFactory

            Environment env = KnowledgeBaseFactory.newEnvironment();

            env.set(EnvironmentName.ENTITY_MANAGER_FACTORY, entityManagerFactory);

            env.set(EnvironmentName.TRANSACTION_MANAGER, transactionManager);

            env.set(EnvironmentName.GLOBALS, new MapGlobalResolver());

     

            Properties properties = new Properties();

            properties.put("drools.processInstanceManagerFactory", "org.jbpm.persistence.processinstance.JPAProcessInstanceManagerFactory");

            properties.put("drools.processSignalManagerFactory", "org.jbpm.persistence.processinstance.JPASignalManagerFactory");

            KnowledgeSessionConfiguration config = KnowledgeBaseFactory.newKnowledgeSessionConfiguration(properties);

           

            return JPAKnowledgeService.newStatefulKnowledgeSession(kbase, config, env);

    Can you check your classpath to see that you have the correct dependencies set?

    Did you update your applicaiton from a different jBPM version?

    Cheers

    Yes,  I update my application from 5.2 to 5.3

    How did you do that update?

    Are you using maven?
