--------------------------------------------------------------
I have used JBPM5 in Spring Web Application

First, I use the following method to create:

       StatefulKnowledgeSession session = kbase.newStatefulKnowledgeSession();

But, I found that process data and session have not saved to the database


When I use the following methods:

EntityManagerFactory emf = (EntityManagerFactory) Constants.ctx
                                        .getBean("entityManagerFactory");
                    Environment env = KnowledgeBaseFactory.newEnvironment();
                    env.set(EnvironmentName.ENTITY_MANAGER_FACTORY, emf);
                    env.set(EnvironmentName.GLOBALS, new MapGlobalResolver());
                    env.set(EnvironmentName.TRANSACTION_MANAGER, TransactionManagerServices
                                        .getTransactionManager());
                    // 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);
                    StatefulKnowledgeSession session = JPAKnowledgeService
                                        .newStatefulKnowledgeSession(kbase, null, env);
                    // StatefulKnowledgeSession session =
                    // kbase.newStatefulKnowledgeSession();
                    return session;
