messaging system

基本解釋

Some data, such as information from transactions, or some other messaging system, may already be in event format.
有些數(shù)據(jù)（比如來自事務(wù)或其他消息傳送系統(tǒng)的信息）可能已經(jīng)使用了事件格式。
When the two destinations are in the same messaging system, the receive and send can be done in a simple transaction because they involve a single transactional resource.
當兩個目的地在同一個消息傳遞系統(tǒng)中時，接收和發(fā)送可以在一個簡單事務(wù)中進行，這是因為它們只涉及單一的事務(wù)資源。
The JMS client can optionally control this transaction explicitly, such as to coordinate receiving a message from one queue with sending a message on another queue in the same messaging system.
JMS 客戶端可以任意的顯式控制該事務(wù)，比如在同一個消息傳遞系統(tǒng)中，協(xié)同處理從一個隊列接收消息和向另一個隊列發(fā)送消息。

The messaging system is not like traditional e-mail, according to fellow blogger Oliver Chiang.
