I don't know about the error, but I do know that this won't work:
employeeSrv.send();
s = employeeSrv.result.locale.country;
Data Service calls are asynchronous and the result does not exist yet
when you are trying to reference it.
You MUST use a resultHandler called by the result event.
<mx:HTTPService id="employeeSrv" ...
result="onResult(event)".../>
private function onResult(oEvent:Object):Void
{
sLocale = oEvent.result.locale.country;
}

Subject: [flexcoders] why can not get the value?
the purpose of my code is to get the client locale with httpservice
1.locale.jsp
<locale>
<%
String s = request.getHeader("Accept-Language");
System.out.print("locale:"+s);
%>
<language><%=s.substring(0,2)%></language>
<country><%=s.substring(3,5)%></country>
</locale>
if I visit the locale.jsp,it can display the the client locale
2.test.mxml
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml"; >
<mx:HTTPService id="employeeSrv" url="locale.jsp">
</mx:HTTPService>
<mx:Script>
<![CDATA[
var s:String;
function initApp(){
employeeSrv.send();
s = employeeSrv.result.locale.country;
}
]]>
</mx:Script>
<mx:Label text="{s}"></mx:Label>
<mx:Button label="test" click="initApp();"></mx:Button>
</mx:Application>
if I visit the test.mxml,
it show a error in my server :
