Managing web services
The Services Browser lets you manage a list of web services by adding or deleting WSDL URLs from a list. In addition,
when you are editing a ColdFusion file, you can use the Services Browser to generate CFML code to invoke a web
service or to create a web service object. Similarly, when you are editing an ActionScript file, you can use the Services
Browser to generate ActionScript.
To view the list of web services, click the Show Web Services button in the top right corner of the Services Browser view.

Right-click in the Services Browser view.

The code that the Service Browser generates appears in the ColdFusion file. The following is an example of the code
that the Service Browser generates:
<cfinvoke
webservice="http://arcweb.esri.com/services/v2/MapImage.wsdl"
method="convertMapCoordToPixelCoord"
returnVariable="convertMapCoordToPixelCoord" >
<cfinvokeargument name="mapCoord" type="" />
<cfinvokeargument name="viewExtent" type="" />
<cfinvokeargument name="mapImageSize" type="" />
</cfinvoke>
