Stream Error when calling a REST Service

I am trying to do a REST client using AS3, I am following this tutorial :http://help.adobe.com/en_US/as3/dev/WSb2ba3b1aad8a27b061afd5d7127074bbf44-8000.html

My code is the following:

import flash.events.Event;

import flash.events.ErrorEvent;

import flash.events.IOErrorEvent;

import flash.events.SecurityErrorEvent;

import flash.net.URLLoader;

import flash.net.URLRequest;

import flash.net.URLRequestMethod;

import flash.net.URLVariables; 

var url:String = "https://localhost:8443/restcomponent/tesimalex"; 

var requestor:URLLoader = new URLLoader(); 

function restServiceCall():void

{

  trace("Calling REST Service...");

  //Create the HTTP request object

  var request:URLRequest = new URLRequest( url );

  request.method = URLRequestMethod.GET;

  //Initiate the transaction

  requestor = new URLLoader();

  requestor.addEventListener( Event.COMPLETE, httpRequestComplete );

  requestor.addEventListener( IOErrorEvent.IO_ERROR, httpRequestError );

  requestor.addEventListener( SecurityErrorEvent.SECURITY_ERROR, httpRequestError );

  requestor.load( request );

}

function httpRequestComplete( event:Event 😞void

{

  trace( event.target.data );

}

function httpRequestError( error:ErrorEvent 😞void

{

  trace( "An error occured: " + error.toString() );

}

The only diference between my code and the one in the tutorial is the URL variables, that I commented, and the url used.

My REST service is a simple GET, if I type the url in the browser it shows me the JSON returned.

But in my AS3, when I call the method restServiceCall() it returns the following error:

Error opening URL 'https://localhost:8443/restcomponent/tesimalex?' An error occured: [IOErrorEvent type="ioError" bubbles=false cancelable=false eventPhase=2 text="Error #2032: Stream Error. URL: https://localhost:8443/restcomponent/tesimalex?"]

Anyone knows whats wrong?
