中介流——通过中介传递请求和/或服务请求者和服务提供者之间的响应消息。
Mediation flows -- perform mediation on request and/or response messages between the service requester and the service provider.
在中介模块内，根据定义消息流逻辑的一个或多个中介原语，可以将消息增强、转换、记录和传送到不同的服务提供者。
Within the mediation module, messages can be augmented, transformed, logged, and routed to different service providers depending on one or more mediation primitives that define the message flow logic.
当然，这个输入参数包含了来自于原始请求者的输入消息或负载，而返回参数则包含了来自于提供者的响应。
Of course, the input parameter contains the input message, or payload, from the original requestor, while the returned parameter contains the response from the provider.
服务提供者是接受来自服务请求者的消息以执行某项工作(某个任务或活动)的对象。
A service provider is an object that accepts messages from service requestors to execute an item of work? A task or an activity.
每个ESB都必须能够通过JMS从服务使用者接收消息，并将其转发到相应的服务提供者(通过JMS或其他协议，如HTTP)，反之亦然。
Each ESB must be capable of receiving messages via JMS from a service consumer and forward them to the appropriate service provider, over JMS, or over a different protocol (like HTTP), and vice versa.
承载运行时所执行的消息相关性操作从使用者或提供者的角度称为隐式相关性。
Message correlation that's performed by a hosting run time is called implicit correlation from the perspective of the consumer or provider.
资源管理器存储应用程序状态，常常是数据库，但也可能是消息队列服务器（在J2EE 应用程序中，它们将是 JMS提供者）或其他事务性资源。
The RMs store the application state and are most often databases, but could also be message queue servers (in a J2EE application, these would be JMS providers) or other transactional resources.
DebugHandler是一个简单的JAX - RPC处理程序，用于打印服务使用者或提供者发出的SOAP消息。
DebugHandler is a simple JAX-RPC handler, used to print a SOAP message by either the service consumer or provider.
消息进入网关，并路由到最终提供者、提供者Facade或其他中介流。
Messages enter the gateway and are routed onwards to an end provider, to a provider facade or to a further mediation flow.
换句话说就是，JMS提供者可以向消息的发送方保证将消息发送到目的地(一个队列或主题)，并且是一次性发送。
In other words, the JMS provider can assure a message's sender that it was delivered to it's destination (a queue or topic) once and only once.
换句话说，JBI的规范化特性就是所有BC将从各自的消息使用者或提供者接收到的消息转换成通用格式。
In other words, JBI's normalizing feature is a common format into which all BCs transform messages received from their respective service consumers or producers.
相关可以由消息传递中间件自动完成，或由服务提供者使用消息传递中间件提供的相关性api来进行。
Correlation can be either automatically done by messaging middleware, or by the service provider with correlation APIs provided by messaging middleware.
一个或多个提供者应用程序通过发送请求消息并处理响应消息来提供服务，请求者应用程序调用这些服务。
The requestor application invokes services offered by one or more provider applications by sending request messages and processing response messages.
然而，在更典型的提供者场景中，消息流将部分工作委托给一个或多个外部代理。
However, a more typical provider scenario is one in which the message flow delegates some of the work to one or more external agents. For example, a message flow can do one of the following.
