In the BPMN service task in JBPM 4.3 you define the service operation to call as (eg from
the example)
<bpmn:interface id="myInterface"
name="org.jbpm.examples.bpmn.task.service.JavaService">
<bpmn:operation id="myOperation" name="myMethod">
<bpmn:inMessageRef>inputMessage</bpmn:inMessageRef>
<bpmn:outMessageRef>outputMessage</bpmn:outMessageRef>
</bpmn:operation>
</bpmn:interface>
From what I can see in the example unit test this creates a new
instance of the specified java class (JavaService) when the process executes, in fact if
you call the method twice it creates the object twice.
Surely a service is more likely to have a lifecycle external to the process? How can I
'inject' a prexisting service instance into the process? Specifically is it
possible to access externally defined spring beans?
Thanks
