How to Configure the HttpService

Hi,

 I am a newbiee for flex developement .

 Through the HttpService how to Communicate from mxml to Servlet .

 How to specify  the url property to a servlet class .

 my application needs to send the data to servlet class through request ..

 can anybody help me for this

 thanks in advance.

    <mx:HTTPService id="serverSide" url="servlet.php"
useProxy="false" 
method="POST">
 	    <mx:request xmlns="">
 		  <saveData>{textarea1.text}</saveData>
 	    </mx:request>
     </mx:HTTPService>


 your servlet url goes into the url field there, on request the xml data 
contained in saveData would be sent to POST variable, which you should be able 
to retrieve in the normal way in your servlet code (ie. in php through $_POST).

u can use httpservice this way 

 suppose u r using login mxml file in that u can use

 <mx:HTTPService id="LogginReq" url="<a target=_blank 
class=ftalternatingbarlinklarge 
href="http://deepakt:8080/PopMailConnector/servlet/Login"">htt
p://deepakt:8080/P
opMailConnector/servlet/Login"</a> method="POST"
showBusyCursor="true"
  useProxy="false" 
result="event.result.response.result=='OK'?currentState='inbox':msg.text=ev
ent.r
esult.response.message"  
fault="mx.controls.Alert.show(event.fault.faultString)">
  <mx:request>
     <user>{uname.text}</user>
     <pass>{upass.text}</pass>
  </mx:request>
 </mx:HTTPService>
