flex和java工程可以集成到一起。但这个动作，至少要下载eclipse的plug-in。我要演示的是在flex builder3中建立独立的flex工程，然后在eclipse里建立独立的webservice服务。两者松散耦合，只需要webservice接口连接。
直接进入主题，看看java的webservice。
定义一个接口和一个实现：
packagemars.flex;publicinterfaceITest{publicStringtest();publicStringsum(inta,intb);publicStringsum1(String[]s);}
packagemars.flex;publicclassTestimplementsITest{publicStringsum1(String[]ss){intresult=0;for(Strings:ss){intn=0;try{n=Integer.parseInt(s);result+=n;}catch(Exceptione){}}return”thesumis:”+result;}publicStringsum(inta,intb){intsum=a+b;return”thesumis:”+sum;}publicStringtest(){return”javawebservicewelcome!”;}}
发布到tomcat下，地址为：http://localhost:8888/ws4flex/services/ws4flex?wsdl

这里定义了三个方法：
test()是最简单的测试通信。sum(int a,int b)测试传入两个参数时，通信问题。sum1(String[] s)测试数组参数是否能被正确传递。
下面，我们来看看flex工程。

mx:WebService用来定义webservice调用。mx:operation定义webservice中调用的方法。mx:request 定义该方法需要哪些参数
