Transaction marked as rollback only: How do I find the cause

Question

I am having issues with committing a transaction within my @Transactional method:

methodA() {
    methodB()
}

@Transactional
methodB() {
    ...
    em.pers         


        

Answer 1

I finally understood the problem:

methodA() {
    methodB()
}

@Transactional(noRollbackFor = Exception.class)
methodB() {
    ...
    try {
        methodC()
    } catch (...) {...}
    log("OK");
}

@Transactional
methodC() {
    throw new ...();
}

What happens is that even though the methodB has the right annotation, the methodC does not. When the exception is thrown, the second @Transactional marks the first transaction as Rollback only anyway.
