Is there a problem in mixing @Transactional with “jpaApi.withTransaction”?

Play Framework

I was having some trouble making transactions work properly in my play application, and my code is structured in such a way that I cannot afford the time to do it “properly” as it shows in the Play Framework documentation.

Only using @Transactional was not enough because for some reason it was not rolling back when I threw my own exceptions.

So this is the way I managed to make transactions work:

@Transactional
public Result myAction() {
    try {
        return ok(Json.toJson(myServiceClass.doStuff()));
    } catch (BusinessRuleException e) {
        return badRequest(Json.toJson("error"));
    }
}

...

public class MyServiceClass {
    public Bill doStuff() throws BusinessRuleException {
        return jpaApi.withTransaction(() -> {

               //...do a bunch of stuff here

        });
    }
}

Is this fine? Can it cause problems later for some reason?

Turns out the problem was in my Security.Authenticator, which was not finding an EntityManager when I removed the @Transactional. The jpaApi.withTransaction was working fine.
