JBPM + Spring Transaction Exchange

I have inherited an application using jBPM and Spring and am trying to figure out if it is configured the way it should be.

First question: Does jBPM support one JTA transaction (JDBC and / or Hibernate) for multiple activities in the same default transition? If not, can it be customized? So the example below has a way to cover the transaction through Action1 and Action2.

The jBPM activities in this project retrieve services or DAO (JDBC) from the Spring context. For the configuration below, are the jBPM actions and the service / DAO methods they call encapsulated in a single transaction? DAOs and service methods are annotated by @Transactional themselves.

State definition:

<state name="SomeState">
    <event type="node-enter">
    <action class="SomeAction"/>
    </event>
    <transition name="transition1" to="finish">
    <action class="Action1"/>
    <action class="Action2"/>
    </transition>
    <transition name="transition.stop" to="finish"/>
</state>

      

        
        
        
      

    

My jBPM config:

<jbpm-configuration>

    <jbpm-context>
