[JBoss jBPM] - [jBPM4] Task still in Active Activies after being completed
by freiburger
Hi,
I've encountered a problem when evaluating the task activity of jBPM4. Unfortunately the forum search is down at the moment, but I haven't found any posts regarding that issue when searching manually ;)
Configuration:
- jBPM4.0 standalone out of the box, only changed DB to MySQL5
- JDK/Container: Java(TM) SE Runtime Environment (build 1.6.0_14-b08)
Process definition:
| <?xml version="1.0" encoding="UTF-8"?>
|
| <process name="tasktest" xmlns="http://jbpm.org/4.0/jpdl">
| <start name="start" g="77,110,48,48">
| <transition name="to task" to="task" g="-36,-20" />
| </start>
| <task assignee="freiburger" name="task" g="206,127,92,52">
| <transition name="to wait" to="wait" g="-36,-20" />
| </task>
| <state name="wait" g="401,154,92,52">
| <transition name="to end" to="end" g="-41,-20" />
| </state>
| <end name="end" g="543,121,48,48" />
| </process>
|
API using JbpmTestCase:
| public void testTakeTask() {
| /* Create process instance */
| ProcessInstance processInstance = executionService
| .startProcessInstanceByKey("tasktest");
|
| /* Find tasks for freiburger (1 expected) */
| List<Task> taskList = taskService.findPersonalTasks("freiburger");
| assertEquals(1, taskList.size());
| Task task = taskList.get(0);
| assertEquals("task", task.getName());
| assertEquals("freiburger", task.getAssignee());
|
| /* Complete task */
| taskService.completeTask(task.getId());
|
| /* Find tasks for freiburger (0 expected) */
| taskList = taskService.findPersonalTasks("freiburger");
| assertEquals(0, taskList.size());
|
| /* Find active activities ("wait" expected) */
| Set<String> expectedActivityNames = new HashSet<String>();
| expectedActivityNames.add("wait");
| assertEquals(expectedActivityNames, processInstance
| .findActiveActivityNames());
| }

Problem description
So obviously the task was not removed from the current activities after completion. Still the engine moves on to the next activity, but it doesn't show up in the activity list at all. I quite don't understand this behaviour if it is intended, any help is greatly appreciated.
Thanks!

[JBoss jBPM] - What all the required Mbenas for jBPM 3.1.3
by contactnagesh
Hi,
I have downloaded Jboss 4.0.5 GA version from the jboss site and downloaded jBPM 3.1.3, trying to integrate with Jboss 4.0.5 GA. I have made that to work by removing the dom4j.jar file and script changes.
Now we have stripped version of Jboss 4.0.5, deploying jBPM 3.1.3. I am hitting the below Eorror
2009-08-04 10:29:37,775 ERROR [org.jboss.deployment.scanner.URLDeploymentScanner] (main) Incomplete Deployment listing:
â MBeans waiting for other MBeans â
ObjectName: jboss.jdbc:service=metadata,datasource=DefaultDS
State: CONFIGURED
I Depend On:
jboss.jdbc:service=metadata
â MBEANS THAT ARE THE ROOT CAUSE OF THE PROBLEM â
ObjectName: jboss.jdbc:service=metadata
State: NOTYETINSTALLED
Depends On Me:
jboss.jdbc:service=metadata,datasource=DefaultDS
Can any one Help me, why this error was hitting? what all the required MBenas for the jBPM 3.1.3 to work.
Thanks,
Nag

I follow exactly as JBPM Developers Guide session "16.3 Usage" to setup related XML. However, still cannot find the Spring Bean (my case is "TestCon" ).
The following are the XML and result.
