**1.配置及说明**

*  jar包说明

从官方上下的Blazeds中，默认的配置有四个文件,都在WEB-INF/Flex目录下：services-config.xml、remoting-config.xml、proxy-config.xml、messaging-config.xml。要使用他，首先把lib目录下的jar包拷贝到你自己创建的web项目中去，当然你可以用maven来管理jar包，这样就会方便很多。这里作为demo，我把目录的截图展示一下：

![23114217-b901690b0cc744bc94e8f314ae947da0.png][]

其中xalan.jar在本例中并没有用到，它是处理xml文档的一个jar包。

*  web.xml配置文件

在web.xml中加入监听（就是个设计模式中的观察者模式），来将HttpFlexSession类作为监听器注册到web.xml中，这样当J2EE HttpSession属性和代理属性的变化时候，就会通知FlexSession属性和目前绑定的listener做相应处理。

<listener>
            <listener-class>flex.messaging.HttpFlexSession</listener-class>
        </listener>

加入blazeds提供的servlet，这样当URL请求符合/messagebroker/\*（这个和后面展示的channel中的那个路径对应）模式时候，它会在Servlet容器启动时启动,并在启动时读取配置文件/WEB-INF/flex/services-config.xml.

<servlet>
            <servlet-name>MessageBrokerServlet</servlet-name>
            <display-name>MessageBrokerServlet</display-name>
            <servlet-class>flex.messaging.MessageBrokerServlet</servlet-class>
            <init-param>

                <param-value>/WEB-INF/flex/services-config.xml</param-value>
           </init-param>
            <load-on-startup>1</load-on-startup>
        </servlet>
     
    
        <servlet-mapping>
            <servlet-name>MessageBrokerServlet</servlet-name>
            <url-pattern>/messagebroker/*</url-pattern>
        </servlet-mapping>

配置文件就简单说明到这，有兴趣自己googling。。。。。

**2.创建简单remote例子。**

这里面我就用flexbuilder4.6和myeclipse两个分开来创建项目。我觉得这样舒服，你要是不爽，你也可以装插件，都在eclipse中编译。

*   后代java代码

![复制代码][copycode.gif]

1 package com.bing.test;
    2 
    3 public class HelloWorld {
    4 
    5     public String getHelloWorld(String name){
    6         System.out.println("hello "+name);
    7         return "this is a test for " +name;
    8     }
    9 }

*  远程服务配置文件

![复制代码][copycode.gif]

1 <?xml version="1.0" encoding="UTF-8"?>
     2 <service id="remoting-service" class="flex.messaging.services.RemotingService">
     3 
     4     <adapters>
     5         <adapter-definition id="java-object"
     6             class="flex.messaging.services.remoting.adapters.JavaAdapter"
     7             default="true" />
     8     </adapters>
     9 
    10     <default-channels>
    11         <channel ref="my-amf" />
    12     </default-channels>
    13     
    14     <destination id="helloWorld" channels="my-amf">
    15         <properties>
    16             <source>com.bing.test.HelloWorld</source>
    17         </properties>
    18     </destination>
    19 </service>

*  前台flexbuilder中配置及代码

新建flex项目dstest，在服务器设置这一步，选择如下，当然你也可以创建好项目后在设置。

创建好之后，编写flex代码

编译之后，在myeclipse的项目目录下会出现一个debug目录，如下：

![23163241-e9577ff2ea074058a33a5a292fee4c71.png][]

修改index.jsp页面，加入超链接

![复制代码][copycode.gif]

<html>
    <body>
    <h2>Hello World!</h2>
    <a href="dstest-debug/dstest.html">ddd</a>
    </body>
    </html>

![复制代码][copycode.gif]

好了，这样就可以启动访问了。
