Can you give me more advice if i want to achive that different users start their own process instance of one process in different place and different time,or i can say in different class. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/607659#607659] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]

By the way,when you say the session persistence configurations do you mean the sessioninfo table in the database? -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/607661#607661] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]

            ds.setUniqueName("jdbc/testDS");             ds.setClassName("com.mysql.jdbc.jdbc2.optional.MysqlXADataSource");             ds.setMaxPoolSize(3);             ds.setAllowLocalTransactions(true);             ds.getDriverProperties().put("user", "root");             ds.getDriverProperties().put("password", "root");             ds.getDriverProperties().put("URL", "jdbc:mysql://localhost:3306/jbpm5");             ds.init();             // load up the knowledge base             KnowledgeBase kbase = readKnowledgeBase();             // start a new process instance             EntityManagerFactory emf = Persistence                     .createEntityManagerFactory("org.jbpm.persistence.jpa");             Environment env = KnowledgeBaseFactory.newEnvironment();             env.set(EnvironmentName.ENTITY_MANAGER_FACTORY,                     emf);             env.set(EnvironmentName.TRANSACTION_MANAGER,                     TransactionManagerServices.getTransactionManager());             // create a new knowledge session that uses JPA to store the runtime             // state             StatefulKnowledgeSession ksession=null;             ksession= JPAKnowledgeService.newStatefulKnowledgeSession(                     kbase,                     null,                     env);             JPAWorkingMemoryDbLogger logger = new JPAWorkingMemoryDbLogger(ksession);             ksession.getWorkItemManager().registerWorkItemHandler("Human Task", new WSHumanTaskHandler());             // start a new process instance             Map<String, Object> params = new HashMap<String, Object>();             params.put("employee", "krisv");             ksession.startProcess("com.sample.evaluation", params);            logger.dispose();         } catch (Throwable t) {             t.printStackTrace();         }     }     private static KnowledgeBase readKnowledgeBase() throws Exception {         KnowledgeBuilder kbuilder = KnowledgeBuilderFactory                 .newKnowledgeBuilder();         kbuilder.add(ResourceFactory.newClassPathResource("Evaluation.bpmn"),                 ResourceType.BPMN2);         return kbuilder.newKnowledgeBase();     } The first time i run the code,the processinstance and the tasks are created successfully.But when i run it second time ,exception was occured just like this: javax.persistence.PersistenceException: [PersistenceUnit: org.jbpm.persistence.jpa] Unable to build EntityManagerFactory     at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:677)     at org.hibernate.ejb.HibernatePersistence.createEntityManagerFactory(HibernatePersistence.java:126)     at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:83)     at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:60)     at com.sample.ProcessTest.main(ProcessTest.java:67) Caused by: org.hibernate.HibernateException: Could not obtain BTM transaction manager instance     at org.hibernate.transaction.BTMTransactionManagerLookup.getTransactionManager(BTMTransactionManagerLookup.java:50)     at org.hibernate.impl.SessionFactoryImpl.<init>(SessionFactoryImpl.java:357)     at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1327)     at org.hibernate.cfg.AnnotationConfiguration.buildSessionFactory(AnnotationConfiguration.java:867)     at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:669)     ... 4 more Caused by: java.lang.reflect.InvocationTargetException     at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)     at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)     at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)     at java.lang.reflect.Method.invoke(Method.java:597)     at org.hibernate.transaction.BTMTransactionManagerLookup.getTransactionManager(BTMTransactionManagerLookup.java:47)     ... 8 more Caused by: bitronix.tm.utils.InitializationException: cannot open disk journal     at bitronix.tm.BitronixTransactionManager.<init>(BitronixTransactionManager.java:59)     at bitronix.tm.TransactionManagerServices.getTransactionManager(TransactionManagerServices.java:43)     ... 13 more Caused by: java.io.IOException:The process cannot access the file because another process has locked a portion of the file     at java.io.RandomAccessFile.read(Native Method)     at java.io.RandomAccessFile.readInt(RandomAccessFile.java:720)     at bitronix.tm.journal.TransactionLogHeader.<init>(TransactionLogHeader.java:77)     at bitronix.tm.journal.TransactionLogAppender.<init>(TransactionLogAppender.java:50)     at bitronix.tm.journal.DiskJournal.open(DiskJournal.java:132)     at bitronix.tm.BitronixTransactionManager.<init>(BitronixTransactionManager.java:46)     ... 14 more I do not know what happened above,can you help me out?Waiting for your response,thank you!! -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/607673#607673] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
