In a real life implementation, you use the activities in the palette to add logic in case a fault was returned, retries if the service is not available, or other processing logic you may need.

可以从这里下载PriceCheckerWeb服务的源代码，它们实现了本文中讨论的故障处理。
This article shows you how to facilitate fault handling within a BPEL process so you can make use of modeled faults, even though the Web service does not expose any.
本文将向您介绍如何促进BPEL流程中的错误处理，以便您能够使用建模的错误，即使Web服务未公开任何建模错误。
The interface element defines the Web service operations, including the specific input, output, and fault messages that are passed, and the order in which they are passed.
interface元素定义Web服务操作，包括特定的输入、输出和所传递的错误消息，以及传递那些错误消息的顺序。
And you have a sort of frustrating situation where iPhone users are annoyed that their service is shoddy, but it's kind of their own fault.

Since the fault is not handled inside the BPEL process, it will result in the global transaction rollback, consequently undoing what the EmployeeRegistry Web service has done.
由于未在BPEL流程内处理错误，该错误会导致全局事务回滚，因此会撤销EmployeeRegistryWeb服务已执行的操作。
Since web service clients rely on WSDL to understand the format of request and response messages, WSDL also describes the fault details returned by the web services.
由于Web服务客户机依靠WSDL理解请求和响应消息的格式，WSDL还描述Web服务返回的故障详细信息。
