Method Detail

afterBegin

public void afterBegin()
                throws javax.ejb.EJBException

Implementation of the SessionSynchronization interface. Calls connectToDataSource for acquiring the jdbc connection.

Throws:

javax.ejb.EJBException

beforeCompletion

public void beforeCompletion()
                      throws javax.ejb.EJBException

Implementation of the SessionSynchronization interface. Posts the changes in the bc4j cache to the database by calling postChanges. If a JboException is thrown by postChanges the transaction is marked for rollback and the exception is wrapped in java.rmi.RemoteException. The RemoteException is then thrown back to the container.

Throws:

javax.ejb.EJBException

See Also:

Transaction.postChanges()

afterCompletion

public void afterCompletion(boolean committed)
                     throws javax.ejb.EJBException

Implementation of the SessionSynchronization interface. Forwards the nofication to the transaction handler and then calls disconnectFromDataSource for releasing the jdbc connection.

Throws:

javax.ejb.EJBException

createTransactionHandlerFactory

protected TransactionHandlerFactory createTransactionHandlerFactory()

Overrides:

createTransactionHandlerFactory in class SessionBeanImpl

suspend

public void suspend()

resume

public void resume()

beginTransaction

public void beginTransaction()
                      throws javax.transaction.NotSupportedException,
                             javax.transaction.SystemException,
                             JboException

If the bean is managing the transaction, starts the bean transaction using the javax.transaction.UserTransaction interface and acquires the jdbc connection from the datasource. It's a noop if the bean's transaction is managed by the container.

Throws:

javax.transaction.NotSupportedException

javax.transaction.SystemException

JboException

SessionBeanImpl.connectToDataSource()

commitTransaction

public void commitTransaction()
                       throws javax.transaction.RollbackException,
                              javax.transaction.HeuristicMixedException,
