另外，此方法的可扩展性不如中间件代理方法，因为需要对每个J2EE 1.3客户机应用程序进行手动修改。
Also, this approach is not as scalable as the middleware proxy approach, because it requires manual modification of each J2EE 1.3 client application.
中间件代理方法的一个优势在于，不需要进行任何应用程序开发任务。
One advantage to the middleware proxy approach is that no application development tasks are required.
这种设计模式在中间层中引入了一个应用程序服务器，中间层代理客户端和数据层之间的代理。
This design pattern introduces an application server in the middle tier which brokers connections between clients and the data tier.
这是在没有设置代理的情况下用于从应用程序中间件收集数据的合理选择。
This is a logical choice for collecting data from application middleware in cases where you do not have agents set up.
要实现这些操作，需要有一个应用程序在呼叫的中间位置充当背靠背的用户代理，并提供对上述服务的访问。
To make these actions happen, you need an application to sit in the middle of the call, act as a back-to-back user agent, and provide access to the services mentioned.
在消息传递中间件中，通过使用一个名为消息代理(或队列管理程序)的服务器组件以消息的形式在系统间传递数据来实现连接。
In messaging middleware, connectivity is achieved by passing data between systems through a server component known as a message broker (or a queue manager) in the form of messages.
由于数字化的资产被定义为中间件的构件(artifact)，所以它们可以与其他流程代理程序服务一起进行操作(在一个事务处理中)。
Since the digital assets are defined as an artifact of the middleware, they can be manipulated in conjunction with other Process Broker services, under a single transaction.
Manager组件可以是EMS应用程序或管理多个代理和相关资源的中间智能层。
Manager components can be EMS applications or an intermediate intelligence layer that manages multiple agents and associated resources.
Web服务提供者和使用者应用程序无需更改就可以通过中间件代理进行互操作。
The Web services provider and consumer applications can interoperate through the middleware proxy without changes.
注意：生产者、消费者和消息代理（中间人）不是必须在一个机器上，确实如此，大多数应用程序都这样。
Note that the producer, consumer, and broker do not have to reside on the same machine; indeed in most applications they don't.
CORBA就是一种用于简化分布式应用程序和服务开发的对象请求代理(orb)的中间件标准。
CORBA is an emerging middleware standard for Object Request Brokers (ORBs) that simplifies the development of distributed applications and services.
