Flex RemoteObject 简单应用Demo

主要实现java类方法调用，java对象数组传递，flex数据传递

程序在以下环境编译执行通过：
flex 1.5 Trail Edition
Tomcat/5.0.19
j2sdk1.4.2_10
WindowsXp Sp2


java文件编译后未打包，.class文件直接放到{flex-dir}\WEB-INF\classes 目录下
实体User.java注意要实现Serializable接口，否则无法将对象传递到Flex。

注意修改Flex的访问控制， flex-config.xml 增加<source>*</source>

<remote-objects>
<whitelist>
<!--whitelistconfigforunnamedobjects-->
<unnamed>
<source>*</source>
</unnamed>
</whitelist>
</remote-objects>
