Why session bean method throw EjbTransactionRolledbackException when RuntimeException was thrown

Question

I am trying to persist the entity with constraint validation, when invoke persist - there is constraint that thrown and the caller get EjbTransactionRolledbackException

Answer 1

so I try to call the validation explicit and throw ConstraintViolationException/RuntimeException and still the caller get EjbTransactionRolledbackException...

Providing the full stacktrace might help. Anyway, I wonder how you are calling your EJB and if you're propagating a transaction, in which case throwing a EJBTransactionRolledbackException is the right behavior in case of a system exception. But the following blog post might help:

Constraint violated, transaction rolled back

When using bean validation on JPA entities within an EJB 3 bean you would actually get an EJBTransactionRolledbackException if there is a constraint violation.

javax.ejb.EJBTransactionRolledbackException: Invalid object at persist time for groups [javax.validation.groups.Default, ]
Caused by: javax.validation.ConstraintViolationException: Invalid object at persist time for groups [javax.validation.groups.Default, ]

This is all nicely according to specification, but not really interesting information. You don't really want to know what happened, you want to know what went wrong.

So I recommend adding the following to your ejb-jar.xml:

   
      
         javax.validation.ConstraintViolationException
         true
      
   

That way you can directly access your violations.
