Interface TransactionServices

All Superinterfaces:

Service

public interface TransactionServices
extends Service

The container must implement the services related to transactional behavior used in JSR-299, if that behavior is going to be used.

The event framework specified by CDI includes the ability to create observer methods which are activated based on the phase and status of a currently active transaction. In order to use these abilities, the container must provide these intermediary services which in turn may interact with an application server and JTA.

Required in a Java EE environment

TransactionServices is a per-deployment service.
