FCKeditor在本地上传图片正常,一到服务器就出现XML request error:not found (404),急呀

web.xml中Servlet的<url-pattern>要和fckconfig.js中的URL引用一致，例如：
web.xml:  <servlet-mapping>
    <servlet-name>Connector</servlet-name>
    <url-pattern>/fckeditor/connector</url-pattern>
  </servlet-mapping>
  
  <servlet-mapping>
    <servlet-name>SimpleUploader</servlet-name>
    <url-pattern>/fckeditor/simpleuploader</url-pattern>
  </servlet-mapping>fckconfig.js：FCKConfig.LinkBrowserURL = FCKConfig.BasePath + 'filemanager/browser/default/browser.html?Connector=/fckeditor/connector' ;
FCKConfig.ImageBrowserURL = FCKConfig.BasePath + 'filemanager/browser/default/browser.html?Type=Image&Connector=/fckeditor/connector' ;
FCKConfig.FlashBrowserURL = FCKConfig.BasePath + 'filemanager/browser/default/browser.html?Type=Flash&Connector=/fckeditor/connector' ;
FCKConfig.LinkUploadURL = '/fckeditor/simpleuploader?Type=File' ;
FCKConfig.ImageUploadURL = '/fckeditor/simpleuploader?Type=Image' ;
FCKConfig.FlashUploadURL = '/fckeditor/simpleuploader?Type=Flash';
