If a MDB has been configured to use the listener port, it will start processing any messages on the queue immediately.
如果 MDB配置为使用该侦听器端口，则它将立即开始处理队列中的任何消息。 ibm
In addition, a task agent can be used to filter messages sent to the MDB by specifying a message selector.
此外，任务代理还可以用于通过指定消息选择器对发送到 MDB的消息进行筛选。 ibm
In the activation spec itself, you identify the queue that the MDB should listen to.
对于激活规范本身，您确定 MDB应该监听的队列。 ibm
In the code show in Listing6, the default value is derived from an EJB environment variable set in the deployment descriptor of the EJB module containing the MDB.
在清单6所示的代码中，缺省值派生自一个 EJB环境变量，该变量是在包含 MDB的 EJB模块的部署描述符中设置的。 ibm
Similarly, for the proxy you can only invoke methods on the interface declared in the MDB's deployment descriptor.
类似地，对于代理，也只能调用在 MDB的部署描述符中声明的接口上的方法。 ibm
The existing MDB application is not affected by this change either.
现有的 MDB应用程序也不受此更改影响。 ibm
The corresponding MDB instance running in that servant region processes the message based on goals set for that class of message.
运行在该服务区域中的对应 MDB实例基于为该消息分类设定的目标处理消息。 ibm
The messages on this bus are the events that are picked up by a special MDB to be transferred for further processing to the so called Event Server application.
此总线上的消息是由一个特殊 MDB选取的事件，这些事件将传输到所谓的“事件服务器”应用程序以作进一步的处理。 ibm
The object returned also implements the interface that the MDB declared in its deployment descriptor.
返回的对象还实现了 MDB在它的部署描述符中声明的接口。 ibm
The work that the MDB method does would then be part of that transaction, including calls to other EJBs.
这样， MDB方法执行的工作，包括对其它 EJB的调用，就会成为事务的一部分。 ibm
This could change in a later version, but currently you must define an MDB for each destination that you want to listen on.
这一限制在以后的版本中可以改变，但目前您只能为每个您想侦听的目的地定义一个 MDB。 ibm
We will also look at some limitations and possible problems you may encounter, how to detect them and how they might be overcome, and also discuss some best practices for MDB load injectors.
我们还将介绍您可能遇到的一些限制和问题，以及如何检测和处理它们，同时讨论有关 MDB负载注入器的一些最佳实践。 ibm
When the Event Service is configured, the Event Service MDB for the default messaging provider is installed along with all resources to receive Events asynchronously.
当配置事件服务时，缺省消息传递提供者的事件服务 MDB与所有资源一起安装，并以异步方式接收事件。 ibm
Before we can run the client, we have to install and deploy the MDB into the application server, which we will do next.
在我们运行客户端之前，必须将 MDB安装并部署到应用程序服务器中。我们接下来就进行操作。 ibm
If the number of deliveries is exceeded and the activation specification is appropriately configured, the failing MDB is paused, providing an opportunity for the failure to be investigated.
如果超过提交次数，并且正确地配置了激活规范，则失败的 MDB会暂停，从而提供调查故障的机会。 ibm
If the MDB is deployed on a different server, the client application does not need to change.
如果将 MDB部署在不同的服务器上，则不需要更改客户机应用程序。 ibm
If we were to specify it, then your MDB could not be configured to work with either programming model at configuration time.
如果我们要指定它，那么就不能在配置时配置 MDB来使用任一编程模型。 ibm
If you wish, you can use this feature to test our sample MDB as well.
如果愿意，您也可以使用该特性来测试样例 MDB。 ibm
In our scenario, however, we are not using this, since the MDB only supports one operation anyway.
不过在本文的示例中，我们不使用此应用程序，因为 MDB仅支持一种操作。 ibm
The last thing we need is the activation specification, which is new for J2EE1.4 and binds the MDB to the queue.
