Uses of TransactionNotInProgressException in org.exolab.castor.jdo.engine
 

Methods in org.exolab.castor.jdo.engine that throw TransactionNotInProgressException
protected  TransactionContext AbstractDatabaseImpl.getTransaction()
          Returns the currently active transaction, if any.
abstract  void AbstractDatabaseImpl.commit()
          Commits and closes the transaction. All changes made to persistent objects during the transaction are made persistent; objects created during the transaction are made durable; and, objects removed during the transaction are removed from the database.

In other words, any modifications to any data objects which are queried/loaded/created/update to this database is automatically stored to the database and visible to subsequence transactions. (ie. update is solely used for long transaction support and should not be called for any data object queried/loaded/created in the this transaction.)

If the transaction cannot commit, the entire transaction rolls back and a TransactionAbortedException exception is thrown.

After this method returns, the transaction is closed and all persistent objects are transient. Using Database.begin() to open a new transaction will not restore objects to their persistent stage.

abstract  void AbstractDatabaseImpl.rollback()
          Rolls back and closes the transaction. All changes made to persistent objects during the transaction are lost, objects created during the transaction are not made durable and objects removed during the transaction continue to exist.
 TransactionContext AbstractDatabaseImpl.getCurrentTransaction()
          Gets the current Castor transaction in use.
 void GlobalDatabaseImpl.commit()
           
 void GlobalDatabaseImpl.rollback()
           
 void LocalDatabaseImpl.commit()
           
 void LocalDatabaseImpl.rollback()
