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

disable the transactionmanager in your Bean.xml

comment out these lines, and you'll see the exception causing the rollback ;)
