Error loading folders and files using virtual host

I'm interested in using FCKEditor for my Java Servlet application.
I am using virtual host and the FCKeditor-2.3.jar.

I haven't got any problem if not use virtual host, for example: http://localhost:9030/myApp, so, I can see the folder, files and I can upload files too to any directory.

I have problem using, for example, the following url: http://demo.example.domain.com:9030

Tomcat conf (virtual host):
--------------------
<Host appBase="C:\virtual\myApp" name="demo.example.domain.com">
<Context docBase="" path="">
<ResourceLink global="jdbc/myApp" name="ds/myApp" type="javax.sql.DataSource" />
</Context>
</Host>
--------------------

I have the followwing error:
--------------------
The server didn't send back a proper XML response. Please contact your system administrator.
XML request error: /scripts/Connector (404)
Requested URL:
http://demo.example.domain.com:9030/scr ... 2063018681

HTTP Status 404 - /scripts/Connector
type Status report
message /scripts/Connector
description The requested resource (/scripts/Connector) is not available.
--------------------
The error appear in the oConnector.SendCommand = function( command, params, callBackFunction ) method in the browser.html file (editor/filemanager/browser/default/browser.html), when trying to do the following:
--------------------
oXML.LoadUrl( sUrl, callBackFunction ) ; // Asynchronous load.
--------------------
Does anyone know why this does not work?
Thanks in advance.
