Overview

JBossJTA is made up of a number of a components and interfaces. The interfaces can be used when

you change the transaction manager implementation, i.e. plugin a thirdparty implementation.

Interfaces

• JBossXATerminator - adds extra methods to the XATerminator interface required by JBossJCA

• LastResource - a tagging interface used by JBossJCA's LocalXAResource to say it wants to take part in the LastResourceGambit

• TransactionManagerServiceMBean - an interface to be implemented by other transaction manager implementations to give other mbeans access to the transaction manager

• TranactionPropagationContextFactory - used to obtain the TPC on the client side

• TransactionPropagationContextImporter - used to import a TPC

• TransactionTimeoutConfiguration - implement this to expose information about transaction timeout configuration

• XAExceptionFormatter - a plugin to format XAExceptions into human readable errors

Implementation

• GlobalId - identifies only the global part of a XID

• LocaIId - the internal id of a transaction

• TransactionImpl - the implementation of javax.transaction.[Transaction|Transaction]

• TransactionManagerService - the management service for the tranasction manager

• TxManager - the transaction manager implementation (also implements many of the above interfaces)

• XidFactory - a factory for XidImpls

• XidImpl - an implementation of Xid

Helpers

• TransactionLocalDelegateImpl - an implementation of TransactonLocalDelegate used when the transaction manager does not implement TransactionLocalDelegate

• TransactionLocalDelegate - methods to implement a transaction local

• TransactionLocal - stores values per transaction, similar to ThreadLocal, except per transaction

• TxUtils - some helper functions for transaction handling
