GetHttpRequest into fckxml.js

Hi all.
Application Server: WSAD 5.1.1
Platform J2EE.
fckeditor 2.1.1
fckeditor.java 2.3

I've encapsulated fckeditor into my application.
It works good except for filebrowsing.
I followed the instructions about fckeditor.java (http://wiki.fckeditor.net/Developer%27s ... ation/Java)
except for the loading of the editor whit the tag FCK.
So, I changed my web.xml and fckconfig.js

This is what happens when I push the "Look at on server" button into the Property Image Window (mypath= the path of my web application):
1) It is called the function OpenServerBrowser(type, url, width, height) into fck_image.js that calls window.open( url, "FCKBrowseWindow", sOptions ) where
url = mypath/FCKeditor/editor/filemanager/browser/default/browser.html?Type=Image&Connector=connectors/jsp/connector
2) Into browser.html it's called the function oXML.LoadUrl( sUrl, callBackFunction ) where sUrl is
mypath/FCKeditor/editor/filemanager/browser/default/browser.html?Type=Image&Connector=connectors/jsp/connector?Command=GetFoldersAndFiles&Type=Image&CurrentFolder=/
3) Into fckxml.js the function GetHttpRequest returns new ActiveXObject("MsXml2.XmlHttp").
At this time oXmlHttp.readyState = 0;
After oXmlHttp.open( "GET", urlToCall, bAsync )
oXmlHttp.readyState begins 1.
oXmlHttp.send( null ) returns the alert:
"XML Request error: Not found (404)".

The result is that the frame of the filesystem browsing is empty (I think that the servlets connector don't start).

Besides, the uploading function, after the choice of the file, remains in infinite wait....

Thanks a lot for any help.
