问FCKeditor在jsp中文件上传的配置问题。点“发送到服务器上”，没反应啊！！！！！！！！！！

         我配置好的FCKeditor，是可以用的。但是上传文件功能不能用，点击“发送到服务器上”按钮没反应，无论我按照网上怎么配置都不好使，困扰我一个多月了啊
          
           我把FCKeditor放在项目的webroot目录下，webroot下新建文件夹UserFiles ，也建了File和Image
          下面是web.xml
          <servlet>
<servlet-name>Connector</servlet-name>
<servlet-class>com.fredck.FCKeditor.connector.ConnectorServlet</servlet-class>
<init-param>
<param-name>baseDir</param-name>
<param-value>/UserFiles/</param-value>
</init-param>
<init-param>
<param-name>debug</param-name>
<param-value>true</param-value>
</init-param>
<load-on-startup>2</load-on-startup>
</servlet> <servlet>
<servlet-name>SimpleUploader</servlet-name>
<servlet-class>com.fredck.FCKeditor.uploader.SimpleUploaderServlet</servlet-class>
<init-param>
<param-name>baseDir</param-name>
<param-value>/UserFiles/</param-value>
</init-param>
<init-param>

</init-param>
<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>
  
        <servlet-mapping>
            <servlet-name>SimpleUploader</servlet-name>
            <url-pattern>/FCKeditor/editor/filemanager/upload/simpleuploader</url-pattern>
       </servlet-mapping>
       fckconfig.js也改了，如下：       FCKConfig.LinkBrowserURL =FCKConfig.BasePath + "filemanager/browser/default/browser.html?Connector=connectors/jsp/connector" ;  
       FCKConfig.ImageBrowserURL =FCKConfig.BasePath + "filemanager/browser/default/browser.html?Type=Image&Connector=connectors/jsp/connector" ;  
       FCKConfig.FlashBrowserURL = FCKConfig.BasePath + "filemanager/browser/default/browser.html?Type=Flash&Connector=connectors/jsp/connector" ;   
       FCKConfig.LinkUpload = true ;
       FCKConfig.LinkUploadURL = FCKConfig.BasePath + 'filemanager/upload/simpleuploader?Type=File' ;   
       FCKConfig.ImageUpload = true ;
       FCKConfig.ImageUploadURL = FCKConfig.BasePath + 'filemanager/upload/simpleuploader?Type=Image' ;   
       FCKConfig.FlashUpload = true ;
       FCKConfig.FlashUploadURL = FCKConfig.BasePath + 'filemanager/upload/simpleuploader?Type=Flash' ;  
       jsp文件：
        <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>       <%@taglib uri="/WEB-INF/FCKeditor.tld" prefix="FCK"%>       <html>       <head>       <title>index</title>        </head>       <body bgcolor="#ffffff">       <form action="postdata.jsp" name="form1" method="POST">       文档标题：<input type="text" name="test" value="测试数据" />       <FCK:editor id="EditorDefault" basePath="/FCKeditor/"                            fontNames="宋体;Arial;Courier New;Times New Roman;Verdana"                            imageBrowserURL="/FCKeditor/editor/filemanager/browser/default/browser.html?Type=Image&Connector=connectors/jsp/connector"                            linkBrowserURL="/FCKeditor/editor/filemanager/browser/default/browser.html?Connector=connectors/jsp/connector"                            flashBrowserURL="/FCKeditor/editor/filemanager/browser/default/browser.html?Type=Flash&Connector=connectors/jsp/connector"                            imageUploadURL="/FCKeditor/editor/filemanager/upload/simpleuploader?Type=Image"                            linkUploadURL="/FCKeditor/editor/filemanager/upload/simpleuploader?Type=File"                            flashUploadURL="/FCKeditor/editor/filemanager/upload/simpleuploader?Type=Flash">                            以下内容为 <strong>测试数据</strong>. 欢迎使用 <a href="http://www.fredck.com/fckeditor/">FCKeditor</a>.              </FCK:editor>              <input type="submit" value="提交"/>              </form>              </body>              </html>
