如何配置与使用CKEDITOR
安装：　
1.　下载CKEDITOR的文件，解压后复制到工程的WEBROOT目录下就OK！
引用CKEDITOR的JS文件：
2.新建JSP页面，添加其JS文件
<link rel="stylesheet" type="text/css" href="richtext.css">
<script type="text/javascript" src="<%=basePath%>/fckeditor/ckeditor.js"></script>
<script type="text/javascript" src="<%=basePath%>/fckeditor/richtext.js"></script>

替换textarea标签：
<textarea rows="15" cols="40" name="Content" ></textarea>
    <script type="text/javascript">
     var uri = encodeURIComponent("/upload/");
CKEDITOR.replace( 'Content' ,{
   filebrowserImageUploadUrl : 'servlet/uploadImage?filePath='+uri   // 点击上传到服务器会执行uploadImage这个servlet
    });
               </script>

// uploadImage servlet
