[JBoss jBPM] - Transition Exception Handling with Tasks
by kaisor
I am using jbpm 3.1.2.
suppose there are two tasks.
Task-A with actor-A
Task-B with actor-B.
Transition t from task-A to Task-B.
i add an actionHandler in this transition t.
At beginning, actor A has a task and triggers the transition t.
If there is no exception-handler defined and this actionhandler throws an exception, then actor-B receive no new task and actor-A lost this task.
so i add an default exception-handler which does nothing indeed. And now if the actionhandler throws exceptions, actor B will receive a new TaskInstance. TaskA of Actor A will be closed.
but what i really want is in case the actionhandler throws exception, the actor A should still hold the task, and Actor B by no means receives any new tasks.
How can I achieve this?

[EJB 3.0] - Service MBean dependencies (on EJB 3.0)
by gsferra＠imnet.it
Hello,
I've a standard JBoss Service MBean that depends on two EJB 3.0, an entity (accessed by a stateless facade bean) and a message driven (that create and bind a JMS queue).
The Service MBean implementation
| import org.jboss.system.ServiceMBean;
|
| public interface MyServiceMBean extends ServiceMBean {
| }
|
| import org.jboss.system.ServiceMBeanSupport;
|
| public class MyService extends ServiceMBeanSupport implements MyServiceMBean {
| ...
| }
|
jboss-service.xml
| <?xml version="1.0" encoding="UTF-8"?>
| <!DOCTYPE server PUBLIC "-//JBoss//DTD MBean Service 4.0//EN" "http://www.jboss.org/j2ee/dtd/jboss-service_4_0.dtd">
| <server>
| <mbean code="MyService" name="test:service=MyService">
| <depends>jboss.j2ee:service=EJB3,name=MyEntityFacadeBean</depends>
| <depends>jboss.j2ee:service=EJB3,name=MyMessageDrivenBean</depends>
| </mbean>
| </server>
|
When I start up JBoss AS I got these messages:
...

--- MBeans waiting for other MBeans ---
ObjectName: test:service=MyService
State: CONFIGURED
I Depend On:
jboss.j2ee:service=EJB3,name=MyEntityFacadeBean
jboss.j2ee:service=EJB3,name=MyMessageDrivenBean
--- MBEANS THAT ARE THE ROOT CAUSE OF THE PROBLEM ---
ObjectName: jboss.j2ee:service=EJB3,name=MyEntityFacadeBean
State: NOTYETINSTALLED
Depends On Me:
test:service=MyService
Looking at the JMX console everything seems to be ok, the service is registered (but it doesn't work), the EJB 3.0 its working and bounded and the message driven bean JMS queue is bounded. What I missing?
