Java Programming

Hi, I hope there will some help for my problem:

I'm using Windows + Tomcat 5.5

I have a javascript that does :

<script language="javascript">
function sendXML()
{
var str = "<testing1>1234</testing>";

var tempdom= new ActiveXObject("MSXML2.DOMDocument");
tempdom.async = false;
tempdom.loadXML(str);

var xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");

try{
xmlhttp.Open("POST","http://localhost:8081/emr/jsp/b.jsp",false);
xmlhttp.Send(tempdom.xml);
var s=xmlhttp.responseText;
alert (s);
}
catch(e){alert(e.reason)}
}
</script>

When this function is triggered, I wish to post the xml data <testing>1234</testing> to the b.jsp. I want b.jsp to receive the xml data and process it. The jsp is simple:

<%@ page import ="javax.xml.parsers.*"%>
<%
try
{
DocumentBuilderFactory Dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder bd = Dbf.newDocumentBuilder();
org.w3c.dom.Document mainDoc=bd.parse(request.getInputStream());

out.print ("OK");
}
catch (Exception ex)
{
ex.printStackTrace();
}

%>

When this b.jsp is executed, the message "OK" does not comes out. And checking the log file from tomcat gives me:

Any help will be appreciated.

Thanks a lot.
