下载后将blazeds.war部署到tomcat下即可。

Flex Builder插件的安装不再作介绍

开发工作为MyEclipse:

1.新建一个Flex工程

按照图中进行配置
2.下一步:

指定已经下载的blazeds.war
3.下一步.

配置url
4.完成后右键配置工程属性:

注意context的修改，不然运行程序会报404.

5.新建一个测试类:

[html]? 
   view plain 
   copy 
    
   
 package?com;??
 ??
 public?class?HelloWorld??
 {??
 ????public?String?say(String?username)??
 ????{??
 ????????System.out.println("hello");??
 ????????return?"你好!"?+?username;??
 ????}??
 ??????
 ????public?String?login(String?username,String?password)??
 ????????System.out.println("login");??
 ????????if(username.equals("admin")?&&?password.equals("admin"))??
 ????????{??
 ????????????return?"success";??
 ????????}??
 ????????else??
 ????????????return?"failure";??
 ????}??
 }??

6.配置web-inf/flex 下的remoting-config.xml文件：

copy 
    
   

<?xml?version="1.0"?encoding="UTF-8"?>??

<service?id="remoting-service"???
????class="flex.messaging.services.RemotingService">??
????adapters ????????adapter-definition?id="java-object"?class="flex.messaging.services.remoting.adapters.JavaAdapter"?default="true"/>??
</default-channelschannel?ref="my-amf" ??????
destination?id="helloworld"properties>??
????????????source>com.HelloWorlddestination>??????
service>??

7.编写mxml文件：

copy 
    
   

version

"1.0"

encoding

"utf-8"

mx:Application

xmlns:mx

"http://www.adobe.com/2006/mxml"

layout

"absolute"

mx:Script ????<![CDATA[?

????????import?mx.rpc.events.ResultEvent;?

????????import?mx.controls.Alert;?

????????//hello事件?

????????private?function?helloClick():void?

????????{?

????????????this.hello.say(this.username.text);?

????????}?

?????????

????????//登录事件??

????????private?function?loginClick():void?

????????????this.login.login(this.username.text,this.password.text);?

????????//处理hello事件?返回值?

????????private?function?resultHandler(e:ResultEvent):void?

????????{?

????????????Alert.show(e.result.toString());?

????????}?

????????//处理登录事件返回值?

????????private?function?resultLoginHandler(e:ResultEvent):void?

????????????Alert.show(e.result?as?String);?

????]]>??

??????

mx:RemoteObject?id="hello"?destination="helloworld"?result="resultHandler(event)"?/>??????

mx:RemoteObject?id="login"?destination="helloworld"?result="resultLoginHandler(event)"?/>??????????

mx:TextInput?id="username"?x="187"?y="99"?width="119"/>??

????mx:Label?x="123"?y="101"?text="username:"mx:Label?x="123"?y="141"?text="password:"mx:TextInput?id="password"?x="187"?y="139"?width="119"? ??????

mx:Button?x="241"?y="184"?label="Login"?click="loginClick()"mx:Button?x="123"?y="184"?label="HelloWorld"?click="helloClick()"mx:Application>??
