"Load users and groups to Human task service" To view the discussion, visit: https://community.jboss.org/message/762488#762488 -------------------------------------------------------------- Hi everybody! I'm using jBPM 5.3.0.Final (except jbpm-human-task which version is 5.3.0.CR1, because something is wrong with my pom.xml or maven repo) and JBoss 7.1.1. On application startup I'm loading users and groups data to Human Task Service. Here is the code: private static void startHumanTaskService() { EntityManagerFactory emf = Persistence.createEntityManagerFactory("org.jbpm.task"); TaskService taskService = new TaskService(emf, SystemEventListenerFactory.getSystemEventListener()); // init users and groups TaskServiceSession taskServiceSession = taskService.createSession(); for (String username : UsersUtils.getUsers()) { taskServiceSession.addUser(new User(username)); } for (String group : UsersUtils.getGroups()) { // guest group already registered? Really? if (!group.equals("guest")) { taskServiceSession.addGroup(new Group(group)); } } MinaTaskServer taskServer = new MinaTaskServer(taskService); // bind to JNDI try { new InitialContext().bind(TASK_SERVER_JNDI_NAME, taskServer); logger.info("save " + taskServer + " to " + TASK_SERVER_JNDI_NAME); } catch (NamingException exception) { logger.error("unable to bind task server", exception); } // start the server Thread thread = new Thread(taskServer); thread.start(); } But If I try load "guest" group I have the following exception 15:47:38,944 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/my-jbpm]] (MSC service thread 1-2) Exception sending context initialized event to listener instance of class com.example.my.jbpm.MyJbpmServletContextListener: java.lang.RuntimeException: Operation failed at org.jbpm.task.service.TaskServiceSession.doOperationInTransaction(TaskServiceSession.java:902) [jbpm-human-task-5.3.0.CR1.jar:5.3.0.CR1] at org.jbpm.task.service.TaskServiceSession.persistInTransaction(TaskServiceSession.java:868) [jbpm-human-task-5.3.0.CR1.jar:5.3.0.CR1] at org.jbpm.task.service.TaskServiceSession.addGroup(TaskServiceSession.java:101) [jbpm-human-task-5.3.0.CR1.jar:5.3.0.CR1] at com.example.my.jbpm.utils.jbpm.JbpmApiUtils.startHumanTaskService(JbpmApiUtils.java:149) [classes:] at com.example.my.jbpm.utils.jbpm.JbpmApiUtils.initEngine(JbpmApiUtils.java:244) [classes:] at com.example.my.jbpm.MyJbpmServletContextListener.contextInitialized(MyJbpmServletContextListener.java:19) [classes:] at org.apache.catalina.core.StandardContext.contextListenerStart(StandardContext.java:3392) [jbossweb-7.0.13.Final.jar:] at org.apache.catalina.core.StandardContext.start(StandardContext.java:3850) [jbossweb-7.0.13.Final.jar:] at org.jboss.as.web.deployment.WebDeploymentService.start(WebDeploymentService.java:90) [jboss-as-web-7.1.1.Final.jar:7.1.1.Final] at org.jboss.msc.service.ServiceControllerImpl$StartTask.startService(ServiceControllerImpl.java:1811) at org.jboss.msc.service.ServiceControllerImpl$StartTask.run(ServiceControllerImpl.java:1746) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) [rt.jar:1.6.0_31] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) [rt.jar:1.6.0_31] at java.lang.Thread.run(Thread.java:662) [rt.jar:1.6.0_31] Caused by: javax.persistence.EntityExistsException: a different object with the same identifier value was already associated with the session: [org.jbpm.task.Group#guest] at org.hibernate.ejb.AbstractEntityManagerImpl.convert(AbstractEntityManagerImpl.java:1359) [hibernate-entitymanager-3.6.9.Final.jar:3.6.9.Final] at org.hibernate.ejb.AbstractEntityManagerImpl.convert(AbstractEntityManagerImpl.java:1315) [hibernate-entitymanager-3.6.9.Final.jar:3.6.9.Final] at org.hibernate.ejb.AbstractEntityManagerImpl.convert(AbstractEntityManagerImpl.java:1321) [hibernate-entitymanager-3.6.9.Final.jar:3.6.9.Final] at org.hibernate.ejb.AbstractEntityManagerImpl.persist(AbstractEntityManagerImpl.java:843) [hibernate-entitymanager-3.6.9.Final.jar:3.6.9.Final] at org.jbpm.task.service.persistence.TaskPersistenceManager.saveEntity(TaskPersistenceManager.java:200) [jbpm-human-task-5.3.0.CR1.jar:5.3.0.CR1] at org.jbpm.task.service.TaskServiceSession$14.doOperation(TaskServiceSession.java:870) [jbpm-human-task-5.3.0.CR1.jar:5.3.0.CR1] at org.jbpm.task.service.TaskServiceSession.doOperationInTransaction(TaskServiceSession.java:890) [jbpm-human-task-5.3.0.CR1.jar:5.3.0.CR1] ... 13 more Is that true that "guest" group already registered in jBPM? How can I check is currently inserting group persisted or not? Thank you for any help.
