配置 BlazeDS
BlazeDS 有 4 个配置文件：
messaging-config.xml：定义发布-订阅消息传送信息
proxy-config.xml：为 HTTP 和 Web 服务提供代理服务信息
remoting-config.xml：定义用于远程服务的信息，比如本文应用程序的配置文件
services-config.xml：引用其他配置文件且提供安全约束、通道和日志记录的优异配置文件
清单 6 展示了 services-config.xml 文件。注意，对于本文应用程序，只有 remoting-config.xml 文件是相关的，因为应用程序仅使用了 BlazeDS 远程服务。
