Ive been banging my head on the wall for hours with this one, hopefully
someone will know what Im doing wrong here :\
The Goal:
I have an xml file that is generated on the fly via JSP which I want to
load into a Microsoft.XMLHT TP ActiveX object and manipulate via
javascript on the client side. Data is retreived from the server at the
request of the javascript without having to reload the page.
The Problem:
For the JSP to dynamically output xml, the file must have the extension
JSP, which is set to the mime type of dynamo-internal/html on the
server side (as we are using ATG Dynamo). But the javascript on the
client side will not retrieve anything unless the file extension is
..xml (or the mime type is recognized as text/xml). So the only way I
can get it to work is to change the extension to .xml, which then of
course amkes it so that the server will not process any of the JSP
code.
Ive tried to override the mime type within the javascript, using the
setRequestHeade r method after opening the file, but no luck. A call to
alert the value of req.responseXML .xml after the send() turns up empty.
Ive only gotten it to work if I use a static xml file in palce of the
jsp. Sample of the javascript code is below:
if (window.XMLHttp Request) {
// branch for native XMLHttpRequest object - THIS WORKS
req = new XMLHttpRequest( );
req.overrideMim eType("text/xml");
req.onreadystat echange = processReqChang e;
req.open("GET", "models.jsp?cId =300006&mId=TAC 24", true);
req.send(null);
} else if (window.ActiveX Object) {
// branch for IE/Windows ActiveX version - NOT WORKING
req = new ActiveXObject(" Microsoft.XMLHT TP");
if (req) {
req.onreadystat echange = processReqChang e;
req.open("GET", "models.jsp?cId =300006&mId=TAC 24", true);
req.setRequestH eader("Content-Type","text/xml");
req.send();
}
}
In looking at the following example the Microsoft gives (bottom of
page):
http://support.microsoft.com/default...;EN-US;Q290591
I just dont see what could be going wrong here.
I should note that I successfully got the script to work using the
XMLHttpRequest object and the overrideMimeTyp e() method. This works
with FireFox adn I think some Mozilla clients, but not with the all
important IE5, which instead uses the XMLHTTP ActiveX control.
Thanks for any help,
Mike
