I've a web including fckeditor component.

I downloaded a 4.5.7 release, installed it and tried with demo data.

when I try to upload a image, the server returns a error "The server didn\'t reply with a proper XML data. Please check your configuration."

<script type="text/javascript" src="${ctx.contextPath}/.resources/fckeditor/fckeditor.js"></script>
<script type="text/javascript" src="${ctx.contextPath}/.resources/fckeditor/fckconfig.js"></script>
<script type="text/javascript">
window.onload=function(){
var oFCKeditor = new FCKeditor('messageText') ;
oFCKeditor.Value = '';
oFCKeditor.Height = '600px';
oFCKeditor.BasePath = "${ctx.contextPath}/.resources/fckeditor/";
oFCKeditor.ReplaceTextarea();
}
