2，在其他应用程序引用该组建
xmlns:common="com.primeton.common.*" 〉
3.使用组建
<common:PagingBar width="100%" height="5%" id="pageBar"/>
4.组建提供使用函数localFunction
protected function test_clickHandler():void
{ firstStart=0;
pageSize=pageBar.pageSize;
pageBar.localFunction=fun;
}
public function fun(pageNo:int):void
{
this.firstStart=(pageNo - 1) * pageBar.pageSize;
pageSize=pageBar.pageSize;
remote.destination = "service";
//remote.endpoint="messagebroker/amf";
//调用J2EE端类中的方法
remote.getFenYeXmls(firstStart,pageSize);
//监听调用成功事件
remote.addEventListener(ResultEvent.RESULT,lineresult);
//监听失败事件
remote.addEventListener(FaultEvent.FAULT,linefault);
} ok
