为了帮助我们调查EII技术如何使门户开发人员受益，我们构建了一个示例门户应用程序，用它来模拟对保险代理的客户服务中心的支持。
To help us investigate how EII technology might benefit portal developers, we built a simple portal application designed to simulate support for a customer service center of an insurance agency.
客户程序代理就是用该文件生成的。
这些代理程序可用于来自代表客户机程序进行操作的协调代理程序，或来自代表现有协调代理程序进行操作的子代理程序的请求。
These agents are available for requests from coordinator agents operating on behalf of client programs, or from subagents operating on behalf of existing coordinator agents.
代理类是客户程序的一部分，并且GSTC将会调用该类来存取服务。
The proxy class is part of the client and the GSTC will call this class to access the service.
这与客户端应用程序形成鲜明对比，其中连接的一端是消息通道代理，另一端是应用程序代码。
Contrast this with a client application where one side of the connection is a message channel agent and the other is application code.
首先，你可以提供一个代理需要实现的接口，并通过该接口从客户端应用程序中访问代理。
First of all, you can provide an interface that the proxy needs to implement and access the proxy from the client application through that interface.
另外，此方法的可扩展性不如中间件代理方法，因为需要对每个J2EE 1.3客户机应用程序进行手动修改。
Also, this approach is not as scalable as the middleware proxy approach, because it requires manual modification of each J2EE 1.3 client application.
这种模式允许应用程序正常运行，但不生成分析数据，直到客户机连接到代理并向其发布指令。
This mode allows the application to run normally, but produces no profiling data until a client attaches to the agent to give it instructions.
客户端应用程序调用通用代理(由它调用服务代理)来调用服务提供者。
The client application calls the general proxy that calls the service proxy to invoke the service provider.
客户机应用程序和ejb代理的源代码必须进行自定义，以反映运行时环境的主机名。
The source code of the client application and the EJB proxy must be customized to reflect the hostnames of your runtime environment.
第一级的必须建立的信任是在客户端连接器和流程代理程序之间。
The first level of trust that must be established is between the Client Connector and the Process Broker.
此部分描述如何创建合适的ejb代理，以便用于将客户机与提供者应用程序集成。
This section describes how to create a suitable EJB proxy that can be used to integrate your client and provider applications.
这种方法允许您逐个地迁移项目，尽管这可能要求客户端应用程序连接到带有不同连接特征的代理。
This approach lets you migrate projects individually, although it means that client applications may need to connect to a broker with different connection characteristics.
这样做将创建并编译代理，构建客户机应用程序，并一步执行它。
Doing so will create and compile the proxies, build the client application, and execute it in one step.
该服务器可让客户端访问由计算单元中的应用程序服务器、节点代理和odr生成的JMX通知。
This server enables the client to access JMX notifications generated by the application servers, node agents, and ODRs within the cell.
这种设计模式在中间层中引入了一个应用程序服务器，中间层代理客户端和数据层之间的代理。
This design pattern introduces an application server in the middle tier which brokers connections between clients and the data tier.
当用户通过KIOSK访问门户应用程序时，客户端显示给门户服务器的信息由用户代理决定。
When a user visits a portal application through a KIOSK, the client shown to the portal server is determined by the user agent.
客户端连接器和本机的流程代理程序建立一种安全的会话，并在基础架构中将玩家的标识与会话关联起来。
The Client Connector establishes a secure session with the local Process Broker, and associates the session with the player’s identity within the infrastructure.
应用程序为了能够使用消息代理进行通信，使用了消息传递客户机库。
In order for applications to communicate using the message broker, they use a messaging client library.
图4展示了一个流程代理程序的网络如何交互来提供客户端和服务提供者之间的连接。
Figure 4 shows how a network of Process Brokers may interact to provide connectivity between clients and service providers.
客户端应用程序可以实例化这些代理中的任一个，并且调用其中的方法。
A client application can instantiate any of these proxies and invoke methods on it.
演示表明代理和客户端应用程序运行在同一台机器上，这是因为使用了本地回环地址。
The illustration shows that the broker is running on the same machine as the client application since the local loopback address is used.
DII客户机可以使用能查找服务信息的服务代理程序在运行时发现这个信息。
A DII client can discover this information at runtime using a service broker that can look up the service's information.
因此，有可能彼此交互的客户端或许是使用了不同的流程代理程序。
Therefore, clients that will potentially interact with each other may be using different Process Brokers.
此客户机JAR文件是在创建EJB代理应用程序时由工具创建的（请参见表2中的任务1）。
This client JAR file was generated by default by the tooling when the EJB proxy application was created (see Task 1 in Table 2).
XML代理还将结果缓存到结果缓存，因为它通过 XML 代理流回到客户端应用程序。
The XML proxy will also cache the result to the result cache as it flows back through the XML proxy to the client application.
图6显示了两个游戏客户端和一个游戏服务器通过流程代理程序进行交互。
Figure 6 shows two game clients and a game server interacting via a Process Broker.
传统的负载测试工具作为代理程序在几台客户机机器上运行。
Conventional load testing tools run as agents on several client machines.
EJB客户机的文件同时包括在客户机应用程序EAR和 EJB代理 EAR 中。
The file for the EJB client is included in both the client application EAR and the EJB proxy EAR.
清单2给出了一个简单的微代理JMS客户机应用程序。
Listing 2 shows a simple micro broker JMS client application.
