If a change is made to any aspect of a service that is coupled, then either the requester or the provider application code (or, more likely, both) will have to change.
如果耦合的服务任何方面有所变化，那么，请求者或提供者的应用程序代码(更可能是两者同时)必须改变。
The third approach assists in the creation of a COBOL-based service requester, which is essentially dealing with a new application.
第三种方法帮助创建基于COBOL的服务请求者，它本质上是创建一个新的应用程序。
The application request (in XML) is put inside a SOAP envelope (also XML) and sent from the requester to the provider; the response that the provider sends back takes the same form.
将应用程序请求（在XML中）放入SOAP信封中（也是 XML ），并从请求者到提供者发送应用程序请求，提供者发回的响应也采用相同的形式。
While the fine-grained interface offers more flexibility to the requester application, it also means that patterns of interaction may vary between different service requesters.
虽然细粒度的接口为请求者应用程序提供了更多的灵活性，它同样也意味着交互的模式可能随着不同的服务请求者而不同。
Thus development environments can use them to automate the process of integrating a service into a requester application.
这样开发环境使用WSDL将集成服务的流程自动处理到请求者应用程序。
You also need to do some JMS configuration to enable the J2EE client application (the service requester) to connect to the WebSphere ESB server using its JMS resources.
您还需要进行一些JMS配置，以便J2EE客户机应用程序(服务请求程序)能够使用其JMS资源连接到WebSphereESB服务器。
This instructs the WebSphere runtime to process any received WS-AT context and dispatch the application component under a global transaction that is coordinated by the external requester.
这将指示WebSphere运行时处理接收的任何WS-AT上下文，并在外部请求程序协调的全局事务下分派应用程序组件。
Now, let's take a look at the SOAP messages between the Web service requester and the Web service provider, and between the browser and the Web application.
现在，让我们研究一下Web服务请求者和Web服务提供者、以及浏览器和Web应用程序之间的SOAP消息。
Restricting the number of things that the requester application code and the provider application code know about each other.
限制请求者应用程序代码和提供者应用程序代码的相互了解。
With one line of code, the catalog controller can now use the requester-side caching capabilities for caching the catalogs returned from the legacy catalog application.
现在只需使用一行代码，Catalog控制器就能够使用请求端缓存功能来缓存从遗留Catalog应用程序返回的Catalog了。
Since the existing catalog application is immutable, and the catalog items are largely read-only, this is an ideal candidate for the requester-side caching pattern.
由于现有Catalog应用程序不能修改，而 Catalog项目大部分都是只读的，因此这就非常适合采用请求端缓存模式。
