Spring's JpaTransactionManager should be used instead of both: DroolsSpringTransactionManager and DroolsSpringJpaManager ------------------------------------------------------------------------------------------------------------------------ Key: JBRULES-2791 URL: https://jira.jboss.org/browse/JBRULES-2791 Project: Drools Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: 5.1.1.FINAL, FUTURE Environment: Spring Based Applications Reporter: Anatoly Polinsky Assignee: Mark Proctor Instead of having two different components: "DroolsSpringTransactionManager" and "DroolsSpringJpaManager" that aim to do the work of "org.springframework.orm.jpa.JpaTransactionManager", and trying to fit a JTA model into it, the Spring's "JpaTransactionManager" itself should be used. And instead of manually managing and constantly getting references to a "proper entity manager" from JpaManger within a SingleSessionCommandService, a @PersistenceContext should be injected. This will decouple SingleSessionCommandService from JpaManager interface, and will allow _any_ JPA provider to inject an entity manager. It has more benefits, such as trust in underline JPA providers ( e.g. Hibernate ) and Spring Transaction Management capabilities to manage the process that they are actually excellent at. /Anatoly -- This message is automatically generated by JIRA. - For more information on JIRA, see: http://www.atlassian.com/software/jira
