[jboss-jira] [JBoss JIRA] (JBRULES-2791) Spring JpaTransactionManager should be used instead of both: DroolsSpringTransactionManager and DroolsSpringJpaManager

[John Bize (JIRA)]

    [ https://issues.jboss.org/browse/JBRULES-2791?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12709875#comment-12709875 ] 

John Bize commented on JBRULES-2791:
------------------------------------

I tried to get some help with the fragile and broken DroolsSpringTransactionManager and it was suggested that I reference my post here.
 
This is my post on the issue: https://community.jboss.org/thread/203535

Can anyone offer some help or suggestions?  Is this issue going to be addressed?

Thanks, John

> 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.
