oracle.jbo.server.DBTransactionImpl
oracle.jbo.server.DBTransactionImpl2
Implementation of DBTransaction
interface for representing both "connected" and "not connected" state. In pre 9.0.3 versions the disconnected and connected state implementation was provided by NullDBTransactionImpl and DBTransactionImpl respectivey. DBTransactionImpl instance was created only when clients initiated the acquisition of a jdbc connection by calling the one of Transaction.connect() or Transaction.connectToDataSource() methods.
Beginning from 9.0.3 Creation of root application module results in creation DBTransactionImpl2 instance in disconnected state. Later when clients request acquistion of jdbc connection this instance migrates from disconnected to connected state.
