?? ?? 最近做项目的时候用到了在线编辑器fckeditor2.6,配置好了以后普通格式的文字都能保持到数据库，唯独需要用到上传图片或其他资源的时候出现问题。
????? 点击fckeditor面板上的图片选项，在浏览服务器的时候就会出现以下错误：
???? The server didn't send back a proper XML response.please contact your system administrator
????? XML request error:OK (200)
?? web.xml相关的配置如下：
?? <servlet>?
??? <servlet-name>Connector</servlet-name>?
??? <servlet-class>?
???? net.fckeditor.connector.ConnectorServlet?
??? </servlet-class>?
??? <load-on-startup>1</load-on-startup>?
</servlet>?
<servlet-mapping>
??? <servlet-name>Connector </servlet-name>
??? <url-pattern>/FCKeditor/editor/filemanager/browser/default/connectors/jsp/connector </url-pattern>
? </servlet-mapping>
???
?
后来在网上查的时候说是配置问题（路径问题），我改了web.xml文件配置如下：
? <servlet>?
??? <servlet-name>Connector</servlet-name>?
??? <servlet-class>?
???? net.fckeditor.connector.ConnectorServlet?
??? </servlet-class>?
??? <load-on-startup>1</load-on-startup>?
</servlet>?
?<servlet-mapping>?
??? <servlet-name>Connector</servlet-name>?
??? <url-pattern>?
???? /fckeditor/editor/filemanager/connectors/*?
??? </url-pattern>?
?</servlet-mapping>
?
后台结果又报错如下了：
