public DataSource getDataSource()

isRollbackOnly

public boolean isRollbackOnly()

Deprecated. use TxService.isRollbackOnly() instead

Specified by:

isRollbackOnly in interface PersistenceService

setRollbackOnly

public void setRollbackOnly()

Deprecated. use TxService.setRollbackOnly() instead

Specified by:

setRollbackOnly in interface PersistenceService

setRollbackOnly

public void setRollbackOnly(boolean rollbackOnly)

Deprecated. use TxService.setRollbackOnly() instead

Specified by:

setRollbackOnly in interface PersistenceService

Throws:

IllegalArgumentException - if rollbackOnly is false

setSession

public void setSession(org.hibernate.Session session)

Injects an external Hibernate session, disabling transaction management.

setSessionWithoutDisablingTx

public void setSessionWithoutDisablingTx(org.hibernate.Session session)

Deprecated. call setSession(session, true) instead

Injects an external Hibernate session without affecting transaction management.

setSession

public void setSession(org.hibernate.Session session,
                       boolean keepTransactionEnabled)

Injects an external Hibernate session. Injecting a session normally disables transaction management. The keepTransactionEnabled parameter can be used to prevent transaction management from being disabled, according to the following table.

is currently enabled?	keep enabled?	enabled onward
true	true	true (no change)
true	false	false
false	any	false (no change)

setSessionFactory

public void setSessionFactory(org.hibernate.SessionFactory sessionFactory)

getTransaction

public org.hibernate.Transaction getTransaction()

setTransaction

public void setTransaction(org.hibernate.Transaction transaction)

isTransactionEnabled

public boolean isTransactionEnabled()

setTransactionEnabled

isPersistenceException

public static boolean isPersistenceException(Exception exception)

Tells whether the given exception or any of its causes is a persistence exception. Currently a persistence exception is an instance of HibernateException.

isLockingException

public static boolean isLockingException(Exception exception)

Tells whether the given exception or any of its causes is a locking exception. Currently a locking exception is an instance of StaleStateException or LockAcquisitionException. Note that Hibernate dialects have limited ability to map native locking error codes to LockAcquisitionExceptions.
