9:55 a.m.
Hi,
I would like to know if somebody could help me.
I have a process with a timer launched at the node-leave event of start-state (t=0 second
in my example). This timer have a duedate of 60 seconds then it takes a transition.
Here is my process:
<?xml version="1.0" encoding="UTF-8"?>
|
| <process-definition xmlns="urn:jbpm.org:jpdl-3.2"
name="process7">
|
| <start-state name="start-state">
| <event type="node-leave">
| <script>System.out.println("Validity period timer
launched.");</script>
| <create-timer name="ValidityPeriodTimer" duedate="2 minutes"
transition="to timeout">
| <script>System.out.println("Validity period expired! Transition to
timeout.");</script>
| </create-timer>
| </event>
| <transition to="state1" name="to state1"/>
| </start-state>
|
| <state name="state1">
| <transition to="state2" name="to state2"/>
| <transition to="timeout" name="to timeout"/>
| </state>
|
| <state name="state2">
| <transition to="end-state" name="to end-state"/>
| <transition to="timeout" name="to timeout"/>
| </state>
|
| <end-state name="end-state"/>
|
| <state name="timeout">
| <transition to="end-state" name="to end-state"/>
| </state>
|
| </process-definition>
I deploy it on my JBoss AS and I start it in my jsf-console.
All is good. Now, i'm doing some tests:
1- If i stop JBoss at 20 seconds and if I restart it at 50 seconds, the transition is
taken at 60 seconds, it's OK.
2- If i stop JBoss at 20 seconds and if I restart it a 70 seconds, the transition is taken
at 71 seconds, it's OK.
BUT:
3- If is stop my DB at 20 sec with JBoss AS always alive and i restart it at 50 seconds,
it's not OK, i have this exception:

and 4- If is stop my DB at 20 sec with JBoss AS always alive and i restart it at 50
seconds, it's not OK, i have the exception. I restart JBoss AS and the transition is
taken.
So my question is : What are all these exceptions? Could somebody help me? I would like to
have my timer working when my DB is relaunched without restart my JBoss AS.
Thx.
