A distrihuted a- synchronous transaction model hased on JMS is provided in this pape r. The model uses non-hlocking transaction disposal mechanism , namely asynchronous transaction disposal , and it supports disposing suh-transitions parallelly , roll-hacking and resuming glohal transaction partly. Using this model in practice can improve the efficiency of transaction disposal and the reliahility of application systems. Distrihuted application systems can use this model to dispose transactions under complex network en- vironment and transactions which need a long time to execute. Key w
