acctually I imitated Philip McCarthy's cart example. but I couldn't get same result.

1. send parameter to servlet

var queryString = "SelectWarehouse=" + param;


var handlerFunction = getReadyStateHandler(xmlhttp4 , updateStockQty );

var youRL = "/StockQtyArryServlet";

xmlhttp4.open("POST", youRL, true);

xmlhttp4.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');

xmlhttp4.onreadystatechange = handlerFunction;

xmlhttp4.send(queryString);

2. here's servlet code

pstmt = con.prepareStatement(query);

pstmt.setString(1, StorageCd);

rs = pstmt.executeQuery();

response.setContentType("application/xml");

response.setHeader("Cache-Control", "no-cache");


out.println (" <?xml version="1.0"?>");


while (rs.next()) {

out.println (" ");

out.println (" ");

out.println (" ");

out.println (rs.getString("GOODS_NM"));

out.println (" ");

out.println (" ");

out.println (rs.getString("STORE_QTY"));

out.println (" ");

out.println (" ");

out.println ("
");



3. then retrieve this xml object here

function getReadyStateHandler( xmlhttp4, responseXmlHandler) {


return function () {


if (xmlhttp4.readyState == 4) {

if (xmlhttp4.status == 200) {
responseXmlHandler(xmlhttp4.responseXML);



} else if (xmlhttp4.status == 404) {

//error
alert("Request URL does not exist");


} else {

//error
alert("Error: status code is " + xmlhttp4.status);


}

}

}

}

4. finally I want to test this xml object whether to correct like this

function updateStockQty (responsedXML){
items =
responsedXML.getElementsByTagName("item");

alert(items.length);

}

Q1. but javascript returns 0, I am not sure that xml file was created properly. how can I prove it?

Q2. I tried to use various DOM command but it didn't work.

thanks in advance and Merry X-mas
