Hi, Just to confirm, Tx Control doesn’t do @Transactional, but it does do JPA without the JPATemplate (i.e. you can just do normal JPA access within a managed block). As for bringing in Java EE guys, that’s great, but at least some of their usage patterns have to change if you want hot-swap and start up order independence to work!
