servlet 返回到flex问题···

[skyqqjie]

servlet 端

if(panchaItem.size()!=0 || whList.size()!=0  || item.size()!=0){
       request.getRequestDispatcher("/exportTemplate/pcBGHJB.jsp").forward(
		request, response);
}else{
	out.write(str);        /*****         我要在这里返回到 页面  弹出提示框  *******/
	}
	}
		
out.flush();
out.close();

页面

var request:URLRequest = new URLRequest();
	           	request.url="/asset/servlet/OutComputerBookServlet";
	           	request.data=sendData;
	           	request.method=URLRequestMethod.GET;
	           	navigateToURL(request,"_self");

我要在else 的时候返回到页面 代码要怎么改啊·····

[水中影子]

<mx:HTTPService id="srv" url="/asset/servlet/OutComputerBookServlet" result="resultHandler(event);"/>

private function resultHandler(evt:ResultEvent):void{
var xml:XML=XML(evt.result);
Alert.show(xml.@node);
}

out.write("<xml node='需要写的内容'></xml>");
