You can't invoke such admin components as a web service. Even
if you could it wouldn't work.
You can only call a method in a component as a webservice if
its access is
remote. However, the methods of the system components
/cfide/adminapi/administrator.cfc, /cfide/adminapi/datasource.cfc,
etc. have either
public or
package access. Verify this by running, for example,
<cfscript>
adminObj =
createObject("component","cfide.adminapi.administrator");
adminObj.login("your_admin_password");
</cfscript>
<cfdump var="#adminObj#">
