I have 3 Maven modules. The first is the GUI, the second is the orchestration and the last for Services, DAOs and the data model. I have 2 datasources, one for the needs of Activti and the other for the data model. I have access the data model data source through JPA/Hibernate.
Questions: - can i handle the data model in the orchestration (in service task by example)? - if yes, must i inevitably use JTA? - i use Spring in my application, can i easily integrate JTA to Activiti (i know the activiti-spring module)?
