Can you give more information about your ejb implementation? What you are trying to know in ejb concurrency management? -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/798558#798558] Start a new discussion in EJB3 at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&con...]

[jBPM] - jBPM 5.4 : how to forward / reassign a task to a group ?

by gonzalad

gonzalad [https://community.jboss.org/people/gonzalad] created the discussion "jBPM 5.4 : how to forward / reassign a task to a group ?" To view the discussion, visit: https://community.jboss.org/message/798550#798550 -------------------------------------------------------------- As mentioned in https://community.jboss.org/thread/221465 https://community.jboss.org/thread/221465, I need to reassign a task to a group. This isn't normally possible via taskService.forward as per the spec WS-Huma,Task 1.0 chapter 4.7.3 Delegating or Forwarding a Human Task : Forwarding is possible if the task has a set of individually assigned potential owners, not if its potential owners are assigned using one or many groups. Is there a good way to do it with jBPM ? For the moment, here's my working code, but it's kind of ugly : public void reassign(TaskSummary taskSummary, String username, String targetGroupname) { Task task = taskService.getTask(taskSummary.getId()); // check if username is in potentialOwners boolean userInPotentialOwners = false; for (OrganizationalEntity entity : task.getPeopleAssignments() .getPotentialOwners()) { if (entity.getId().equals(username)) { userInPotentialOwners = true; break; } } if (!userInPotentialOwners) { org.jbpm.task.User actualOwner = task.getTaskData() .getActualOwner(); // we claim the task just to set actualOwner to current user if (taskSummary.getStatus() == Status.Ready && (actualOwner == null || !actualOwner.getId().equals( username))) { taskService.claim(task.getId(), username); actualOwner = task.getTaskData().getActualOwner(); } // if actualOwner is current user, we add it to potentialOwnersn, // just to call forward - see // https://community.jboss.org/thread/221465?tstart=0 task.getPeopleAssignments().getPotentialOwners().add(actualOwner); } taskService.forward(taskSummary.getId(), username, targetGroupname); // forward reassigns the task. // if the task was already assigned to other groups / users, those groups / users are not removed from potentialOwners // we must do it explicitly PeopleAssignments peopleAssignments = task.getPeopleAssignments(); List<OrganizationalEntity> clonedList = peopleAssignments .getPotentialOwners(); for (OrganizationalEntity entity : clonedList) { if (!entity.getId().equals(targetGroupname) && !entity.getId().equals("Administrator")) { peopleAssignments.getPotentialOwners().remove(entity); } } } Thanks ! -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/798550#798550] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&con...]

[jBPM] - Re: jBPM 5.4 : forwarding task PermissionDeniedException when user is actualOwner but not in potential owners

by gonzalad

Perhaps, changing userIsExplicitPotentialOwner is needed to also check if user belongs to one of the groups contained in task.potentialOwner. I'll do some more tests tomorrow for this and update my temporary solution. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/798410#798410] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&con...]

[EJB3] - MDB connection to remote JMS provider (Webmethods)

by Abhijith Nagarajan

Abhijith Nagarajan [https://community.jboss.org/people/abhijithtn] created the discussion "MDB connection to remote JMS provider (Webmethods)" To view the discussion, visit: https://community.jboss.org/message/798532#798532 -------------------------------------------------------------- Hi Folks, What is the preferred way to connect to remote JMS provider (Webmethods) in Jboss eap 5.1? Is it better to use JMSProviderLoader service of jboss (Jboss resource adapter which uses client jars) or using jms provider resource adapter (jms provider jca implementation). What are the pros and cons of these two approaches? Awaiting the reply. Thanks in advance -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/798532#798532] Start a new discussion in EJB3 at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&con...]

[jBPM] - jBPM skips my rule task nodes except for the last rule task

by John Joel Boss

John Joel Boss [https://community.jboss.org/people/jjsaguit] created the discussion "jBPM skips my rule task nodes except for the last rule task" To view the discussion, visit: https://community.jboss.org/message/798514#798514 -------------------------------------------------------------- using jbpm 5.4 with drools 5.5.0 and eclipse juno I have a test project with a workflow that goes : [start] --> [script printing "Hello 1"] --> [rule task node to print "Rule 1"] --> [script printing "Hello 2"] --> [rule task node to print "Rule 2"] --> [END] The output is: Hello 1 Hello 2 Rule 2 I used AgendaEventListener added to my ksession to fire the rules and I think it works just fine. Full post at https://community.jboss.org/thread/221486 https://community.jboss.org/thread/221486. I built the KnowledgeBuilder as the following: KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); // adding my workflow kbuilder.add(ResourceFactory.newClassPathResource("sample.bpmn"), ResourceType.BPMN2); // adding my first rule with ruleflow-group "test1" kbuilder.add(ResourceFactory.newClassPathResource("test.xls"), ResourceType.DTABLE); // adding my second rule with ruleflow-group "test2" kbuilder.add(ResourceFactory.newClassPathResource("test1.xls"), ResourceType.DTABLE); Funny thing because if I comment out my second rule the output would be: Hello 1 Rule 1 Hello 2 It seems like its only firing the last rule in the list. Any idea whats wrong? Test project attached -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/798514#798514] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&con...]

[jBPM] - Re: jBPM 5.2 set process instance variable from java - NullPointerException

by Salvatore Loria

The problem is that I was not using transactions... Just surround my code in a tm.begin() and tm.commit() and it works fine. I get my tm using the jboss tm locator: TransactionManager tm = TransactionManagerLocator.locateTransactionManager(); tm.begin(); // get and set variables here tm.commit(); Is this the right way to go? -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/733626#733626] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&con...]
