can't upload images using java integration

So I've been able to successfully return files from 'GetFolderAndFiles' command to the image browser. However, when posting the multipart/formdata to the upload servlet it fails..adding further debugging it seems that the request does is empty..i.e. on the upload servlet, the following code

DiskFileUpload upload = new DiskFileUpload();
List items = upload.parseRequest(request);
if (debug) System.out.println("# of items: " + items.size()); // RETURNS 0

This is becoming quite urgent, can anyone help please ?
My custom config looks like:

var _FileBrowserLanguage   = 'jsp' ;   // asp | aspx | cfm | lasso | perl | php | py
var _QuickUploadLanguage   = 'jsp' ;   // asp | aspx | cfm | lasso | perl | php | py
FCKConfig.ImageBrowser = true ;
FCKConfig.ImageBrowserURL = FCKConfig.BasePath + 'filemanager/browser/default/browser.html?Type=Image&Connector=' + encodeURIComponent( FCKConfig.BasePath + 'filemanager/connectors/' + _FileBrowserLanguage + '/connector.' + _FileBrowserExtension ) ;

My connector.jsp contains:

<jsp:forward page="/Connector" />

My web.xml contains:

 <servlet>
     <servlet-name>Connector</servlet-name>
     .
     .
     .
</servlet>
<servlet-mapping>
    <servlet-name>Connector</servlet-name>
    <url-pattern>/Connector</url-pattern>
</servlet-mapping>
