为了强调这两种新元素所造成的不同,请看以下两图,在每个图中,EAR文件用蓝颜色遮蔽,表示应用程序汇编器的影响范围。

与此相反,在图2中,应用程序汇编器可以通过将两个message - destination - ref链接到同一个message - destination,而清楚地表明他或者她的意图。
In contrast, in Figure 2 the application assembler can make his or her meaning entirely clear by linking the two message-destination-refs to the same message-destination.
在这种情况下,应用程序汇编器可以在MDB的部署描述符中指定一个message - destination - link,以表明mdb应当从中收取消息的message - destination。
In this scenario, the application assembler can specify a message-destination-link in the MDB's deployment descriptor to indicate the message-destination from which the MDB should receive messages.
