[jbossts-issues] [JBoss JIRA] (JBTM-3106) Firing an @Initialized(TransactionScoped.class) event

Firing an @Initialized(TransactionScoped.class) event ----------------------------------------------------- Key: JBTM-3106 URL: https://issues.jboss.org/browse/JBTM-3106 Project: JBoss Transaction Manager Issue Type: Enhancement Components: JTA Affects Versions: 5.9.2.Final Reporter: Ondra Chaloupka Assignee: Laird Nelson Priority: Major It would be beneficial to have the CDI-specific wrapper around Narayana's TransactionManagerImple that fires an @Initialized(TransactionScoped.class)-qualified event. For the CDI, it's a good practice. The all built-in scopes have to provide this behaviour. The CDI specification says (in section 6.7): {quote} Portable extensions are encouraged to synchronously fire: * an event with qualifier @Initialized(X.class) when a custom context is initialized, i.e. ready for use, * an event with qualifier @BeforeDestroyed(X.class) when a custom context is about to be destroyed, i.e. before the actual destruction, * an event with qualifier @Destroyed(X.class) when a custom context is destroyed, i.e. after the actual destruction, where X is the scope type associated with the context. A suitable event payload should be chosen. {quote} The {{begin()}} method a Narayana-supplied but CDI-specific transaction manager wrapping Narayana's "ordinary" one should do: {code} @Inject @Initialized(TransactionScoped.class) private Event<Transaction> initializationBroadcaster; @Inject @BeforeDestroyed(TransactionScoped.class) private Event<Transaction> beforeDestructionBroadcaster; @Inject @Destroyed(TransactionScoped.class) private Event<TransactionManager> destructionBroadcaster; // in its begin() method: super.begin(); initializationBroadcaster.fire(this.getTransaction()); // in its commit() and rollback() methods and anywhere else I'm forgetting: beforeDestructionBroadcaster.fire(this.getTransaction()); super.commit(); // or rollback or whatever destructionBroadcaster.fire(this); {code}
