ConnectionEventListener interface provides an event
callback mechanism to enable an application server to receive
notifications from a ManagedConnection instance.
An application server uses these event notifications to manage its connection pool, to clean up any invalid or terminated connections and to manage local transactions.
An application server implements the
ConnectionEventListener interface. It registers a connection
listener with a ManagedConnection instance by using
ManagedConnection.addConnectionEventListener method.
javax.resource.spi.ConnectionEvent
| Modifier and Type | Method and Description |
|---|---|
| public void | connectionClosed(ConnectionEvent
event object describing the source of
the event event)Notifies that an application component has closed the connection. |
| public void | connectionErrorOccurred(ConnectionEvent
event object describing the source of
the event event)Notifies a connection related error. |
| public void | localTransactionCommitted(ConnectionEvent
event object describing the source of
the event event)Notifies that a Resource Manager Local Transaction was committed on the ManagedConnection instance. |
| public void | localTransactionRolledback(ConnectionEvent
event object describing the source of
the event event)Notifies that a Resource Manager Local Transaction was rolled back on the ManagedConnection instance. |
| public void | localTransactionStarted(ConnectionEvent
event object describing the source of
the event event)Notifies that a Resource Manager Local Transaction was started on the ManagedConnection instance. |
| connectionClosed | back to summary |
|---|---|
| public void connectionClosed(ConnectionEvent event) Notifies that an application component has closed the connection. A ManagedConnection instance notifies its registered set of listeners by calling ConnectionEventListener.connectionClosed method when an application component closes a connection handle. The application server uses this connection close event to put the ManagedConnection instance back in to the connection pool.
| |
| connectionErrorOccurred | back to summary |
|---|---|
| public void connectionErrorOccurred(ConnectionEvent event) Notifies a connection related error. The ManagedConnection instance calls the method ConnectionEventListener.connectionErrorOccurred to notify its registered listeners of the occurrence of a physical connection-related error. The event notification happens just before a resource adapter throws an exception to the application component using the connection handle. The connectionErrorOccurred method indicates that the associated ManagedConnection instance is now invalid and unusable. The application server handles the connection error event notification by initiating application server-specific cleanup (for example, removing ManagedConnection instance from the connection pool) and then calling ManagedConnection.destroy method to destroy the physical connection.
