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
