[jboss-user] [JBoss jBPM] - Strange Asynchronous Behaviour of JBPM(3.2.2)
Hi all,
I have deployed the jbpm-enterprise.ear into my existing jpm-jpdl-suite 3.2.2.The ear got
successfully deployed.
However when I am trying to achieve asynchronous execution by declaring one node as
asynch="true" which I tried with the following code:
| <?xml version="1.0" encoding="UTF-8"?>
| <process-definition xmlns="urn:jbpm.org:jpdl-3.2"
name="synch-process">
| <start-state name="start-state1">
| <task name="task-1"></task>
| <transition to="node1"></transition>
| </start-state>
| <node name="node1" async="true">
| <action name="action-1"
class="CustomerActionHandler1"></action>
| <transition to="node2"></transition>
| </node>
| <node name="node2">
| <action name="actio-2"
class="CustomActionHandler2"></action>
| <transition to="end-state1"></transition>
| </node>
| <end-state name="end-state1"></end-state>
| </process-definition>
|
I turned on SOPs in the following classes
:-JmsMessageServiceImpl.java,JobListenerBean.java,ExecuteJobCommand.java,CommandServiceBean.java,CommandListenerBean.java
and redployed the ear.
The classes generated the SOPs properly stating the job message was dumped into the jbpm
job queue and command was executed from the command service bean:
Following is the trace-

17:27:45,381 INFO [STDOUT] Action class of synchronous node is called
.
However in the action class attached with the asynch node I had to write the following
code snippet so that the process continued to the next node:-
| executionContext.getNode().leave(executionContext);
