The ColdFusion sample application sends a request to the page

featureInfo.cfm in the Feature Info frame. As this page is parsed, the map is

cleared, a feature_info request is sent to Autodesk MapGuide LiteView, and

the XML result is captured.

featureInfo.cfm has a custom embedded Java tag that represents the parseXml

Java class (not a Java servlet). The Java class uses the XML, a style-sheet vari-

able, and Xerces and Xalan to parse XML and XSL to create an HTML stream.

The custom tag embeds the HTML, which describes the feature information,

directly in the page. After the ColdFusion page is loaded completely, the

onload tag calls the JavaScript function, showMapSelected():

function showMapSelected(layer,id)

{

var selectFeatureRequest = "map.cfm?FEATURELAYER=" + escape

(layer) + "&ID=" + id + "&BBOX=<cfoutput>#Form.bbox#

</cfoutput>&MODE=identify";

parent.map.document.location = selectFeatureRequest;

}

The function showMapSelected() sends a request to map.cfm, which formulates

the correct request to show the selected feature on the map.

The custom Java tag, embedded in the page, handles XML received by the

CFM in response to a feature_info request. When the ColdFusion server reads

this tag, it executes a small Java class method that accepts XML and a style

sheet as input and returns HTML to the ColdFusion page.

The following diagram shows the process of requesting feature information.
