Dispatcher? Manages an Activation queue of service requests that are pending execution; it decides which request to de-queue next and execute on a service Delegate object that implements the request.

Dispatcher——管理等待执行的服务请求的激活队列；它决定接下来哪个请求退出队列并在实现该请求的Service Delegate对象上执行。

Activation Queue? Maintains method requests pending for execution.

Activation Queue——维护等待执行的方法请求。

Manager - plays the role of Proxy of the active object model; using instances of EventMessage, the Manager determines service invocation requests that are placed into an Activation Queue.

Manager——扮演活动对象模型的代理角色；通过使用EventMessage的实例，Manager确定放入激活队列中的服务调用请求。

Because your Web service also accepts requests using the JMS, you need to create a bus, two queue destinations for incoming and replies, and an activation spec for the message driven bean (MDB).

由于您的Web服务还接受使用JMS的请求，因此需要创建一个总线、两个用于传入和应答的队列目的地和一个用于消息驱动Bean (Message Driven Bean, mdb)的激活规范。

This forms an unbroken chain of requests that include the same activation context.

这形成了一个连续的包含同样活化上下文的请求链。
