getPersistenceBroker

public static org.apache.ojb.broker.PersistenceBroker getPersistenceBroker(org.apache.ojb.broker.PBKey pbKey,
                                                                           boolean allowCreate)

Get an OJB PersistenceBroker for the given PBKey. Is aware of a corresponding PersistenceBroker bound to the current thread, for example when using PersistenceBrokerTransactionManager. Will create a new PersistenceBroker else, if allowCreate is true.

Parameters:

pbKey - PBKey to create the PersistenceBroker for

allowCreate - if a non-transactional PersistenceBroker should be created when no transactional PersistenceBroker can be found for the current thread

Returns:

the PersistenceBroker

Throws:

DataAccessResourceFailureException - if the PersistenceBroker couldn't be created

IllegalStateException - if no thread-bound PersistenceBroker found and allowCreate false

                                                     org.apache.ojb.broker.PBKey pbKey)

Deprecated. in favor of releasePersistenceBroker

Close the given PersistenceBroker, created for the given PBKey, if it isn't bound to the thread.

See Also:

releasePersistenceBroker(org.apache.ojb.broker.PersistenceBroker, org.apache.ojb.broker.PBKey)

releasePersistenceBroker

public static void releasePersistenceBroker(org.apache.ojb.broker.PersistenceBroker pb,
                                            org.apache.ojb.broker.PBKey pbKey)
