TransactionAttributeannotation specifies whether the container is to invoke a business method within a transaction context. The
TransactionAttributeannotation can be used for session beans and message driven beans. It can only be specified if container managed transaction demarcation is used.
The annotation can be specified on the bean class and/or it can be specified on methods of the class that are methods of the business interface or no-interface view.
TransactionAttribute annotation on the
bean class means that it applies to all applicable business
methods of the class. Specifying the annotation on a
method applies it to that method only. If the annotation is applied
at both the class and the method level, the method value overrides
if the two disagree.
The values of the
TransactionAttribute annotation are
defined by the enum
TransactionAttribute annotation is not specified, and
the bean uses container managed transaction demarcation, the semantics of
REQUIRED transaction attribute are assumed.
