Package org.jboss.seam.transaction

Abstracts all possible transaction management APIs behind a JTA-compatible interface.

See: Description

Interface Summary

Interface	Description
LocalEjbSynchronizations	Local interface for EjbTransaction
Synchronizations	Interface for registering transaction synchronizations
UserTransaction	Extends the standard UserTransaction interface with a couple of helpful methods.

Class Summary

Class	Description
AbstractUserTransaction	Base implementation of UserTransaction
CMTTransaction	Wraps EJBContext transaction management in a UserTransaction interface.
EjbSynchronizations	Receives JTA transaction completion notifications from the EJB container, and passes them on to the registered Synchronizations.
EjbTransaction	Dummy component that lets us install the EjbSynchronizations via the tag transaction:ejb-transaction
EntityTransaction	Support for the JPA EntityTransaction API.
FacesTransactionEvents	Produces StatusMessages for JSF in response of certain transaction events.
HibernateTransaction	Support for the Hibernate Transaction API.
NoTransaction	When no kind of transaction management exists.
RollbackInterceptor	Automatically sets the current transaction to rollback only when an exception is thrown.
SeSynchronizations	This implementation does not have access to the JTA TransactionManager, so it is not fully aware of container managed transaction lifecycle, and is not able to register Synchronizations with a container managed transaction.
Transaction	Supports injection of a Seam UserTransaction object that wraps the current JTA transaction or EJB container managed transaction.
TransactionInterceptor	Implements transaction propagation rules for Seam JavaBean components.
UTTransaction	Wraps JTA transaction management in a Seam UserTransaction interface.

Package org.jboss.seam.transaction Description

Abstracts all possible transaction management APIs behind a JTA-compatible interface. Unfortunately, many otherwise-perfectly-intelligent-looking Java developers like to invent their own transaction management APIs when they get bored, even though JTA is well-known to be more than good enough. For example, one of the co-authors of this class was present at the creation of not one but two "alternative" transaction APIs (org.hibernate.Transaction and javax.persistence.EntityTransaction), and is more embarrassed by this than by any other of his many professional blunders.
