IE ok but problems with Chrome

IE ok but problems with Chrome

Hi, I am having trouble with Chrome runing my first jQuery+ajax code, IE is working fine.
My script retrieves a web service via SOAP XML.
I tried CORS=true but Chrome keeps reporting: Origin (ip address) is not allowed by Access-Control-Allow-Origin.
I am testing my code indoors but final destination will be an Android device.
Page is loaded from standart 80 port, web service is called on the 8181 port.
I am using IE ver 9.0.8112.16421, Chrome ver 22.0.1229.94 m, running on Windows 7.
This is a portion of the code:

<!DOCTYPE html>
<html>
<head>
<script src="jquery.js"></script>
<!--   <script src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>  -->
<script>
   $(document).ready(function(){
     $("button").click(function(){
// alert('entrando en script - en button click');
      var productServiceUrl = 'http://172.16.128.111:8181/demows/MV/Buscaseguradogm'; 
      var soapMessage = '';   /* Configure Parameters */
   
      soapMessage =  '<?xml version="1.0"?>';
      soapMessage += '<soapenv:Envelope ';
      soapMessage += 'xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" ';
      soapMessage += 'xmlns:mv="http://172.16.128.111:8181/demows/MV/Buscaseguradogm">';
      soapMessage += '   <soapenv:Header/>';
      soapMessage += '   <soapenv:Body>';
      soapMessage += '      <mv:MV_Buscaseguradogm>';
      soapMessage += '         <mv:programa>'+    $("#programa").val()    +'</mv:programa>';
      soapMessage += '         <mv:nombre1>'+     $("#nombre1").val()     +'</mv:nombre1>';
      soapMessage += '         <mv:nombre2>'+     $("#nombre2").val()     +'</mv:nombre2>';
      soapMessage += '         <mv:apellido1>'+   $("#apellido1").val()   +'</mv:apellido1>';
      soapMessage += '         <mv:apellido2>'+   $("#apellido2").val()   +'</mv:apellido2>';
      soapMessage += '         <mv:apellido3>'+   $("#apellido3").val()   +'</mv:apellido3>';
      soapMessage += '         <mv:certificado>'+ $("#certificado").val() +'</mv:certificado>';
      soapMessage += '         <mv:grupo>'+       $("#grupo").val()       +'</mv:grupo>';
      soapMessage += '      </mv:MV_Buscaseguradogm>';
      soapMessage += '   </soapenv:Body>';
      soapMessage += '</soapenv:Envelope>';

// alert('**ya asigne variable - antes de llamada ajax'+soapMessage);
      $.support.cors = true; 
      $.ajax({
              url: productServiceUrl,
              type: "POST",
              data: soapMessage,
              dataType: "xml",
              crossDomain: true,
              complete: function(){alert("busqueda completada");},
              success: resultado, 
              error:    function(xhr){alert("***** busqueda con error *****"+ xhr.status + ">" + xhr.statusText + ">>" + xhr.errorThrown);}
      });
    });
  });
</script>

Can you please point me in the right direction?
Best regards,
Roberto
