对于FCK edit我尝试了2种方式：

一种是jsp标签导入 ，但我们写的页面是xhtml，标签用不了，尝试找资料去写标签，没成功。
第二种是javascript  方式，这种方式我现在有个问题就是我在每个textarea写一段js，还没想到写成工具调用，各位有时间可以想想。

现在说下具体的配置
1.
 将FCKeditor_2.5.1解压缩,目录结构是 FCKeditor_2.5.1\fckeditor\editor
 将目录editor复制到项目的WebRoot下的fck里面（WebRoot里面建一个目录 叫 fck ，名字随你取），
 将目录fckeditor中的 fckconfig.js、fckeditor.js、fckstyles.xml、fcktemplates.xml拷贝到 fck里面
 然后将FCKeditor-2.3.zip（java）压缩包中\web\WEB-INF\lib\目录下的两个jar文件拷到项目的\WEB-INF\ lib\目录下。
 把其中的src目录下的FCKeditor.tld文件copy到工程的WEB-INF下面。
 
 
 2. 配置web.xml文件，我直接贴我那个了：
 
 <servlet>
        <servlet-name>Connector</servlet-name>
       <servlet-class>com.fredck.FCKeditor.connector.ConnectorServlet</servlet-class>
        <init-param>
           <param-name>baseDir</param-name>
            <!-- 此为文件浏览路径 -->
           <param-value>/UserFiles/</param-value>
        </init-param>
        <init-param>
           <param-name>debug</param-name>
            <param-value>true</param-value>
        </init-param>
       <load-on-startup>1</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>
            <!-- 此为文件上传路径，需要在WebRoot 目录下新建 UserFiles 文件夹 -->
            <!-- 根据文件的类型还需要新建相关的文件夹 Image、 Flash -->
           <param-value>/UserFiles/</param-value>
       </init-param>
        <init-param>
            <param-name>debug</param-name>
            <param-value>true</param-value>
        </init-param>
        <init-param>
            <!-- 此参数为是否开启上传功能 -->
            <param-name>enabled</param-name>
            <param-value>true</param-value>
        </init-param>
        <init-param>
            <param-name>AllowedExtensionsFile</param-name>
            <param-value></param-value>
        </init-param>
       <init-param>
            <!-- 此参数为文件过滤，以下的文件类型都不可以上传 -->
            <param-name>DeniedExtensionsFile</param-name>
            <param-value>php|php3|php5|phtml|asp|aspx|ascx|jsp|cfm|cfc|pl|bat|exe|dll|reg|cgi</param-value>
        </init-param>
        <init-param>
            <param-name>AllowedExtensionsImage</param-name>
            <param-value>jpg|gif|jpeg|png|bmp</param-value>
        </init-param>
        <init-param>
            <param-name>DeniedExtensionsImage</param-name>
            <param-value></param-value>
        </init-param>
        <init-param>
            <param-name>AllowedExtensionsFlash</param-name>
           <param-value>swf|fla</param-value>
        </init-param>
        <init-param>
            <param-name>DeniedExtensionsFlash</param-name>
            <param-value></param-value>
        </init-param>
       <load-on-startup>1</load-on-startup>
    </servlet>
   
<servlet-mapping>
    <servlet-name>Connector</servlet-name>
   <url-pattern>/fck/editor/filemanager/browser/default/connectors/jsp/connector</url-pattern>
</servlet-mapping>

<servlet-mapping>
    <servlet-name>SimpleUploader</servlet-name>
    <url-pattern>/fck/editor/filemanager/upload/simpleuploader</url-pattern>
</servlet-mapping>
 
 
 3.更改fckconfig.js
 
 对应的六个URL等的值替换成以下内容：
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.LinkUploadURL = FCKConfig.BasePath + 'filemanager/upload/simpleuploader?Type=File' ;

FCKConfig.FlashUploadURL = FCKConfig.BasePath + 'filemanager/upload/simpleuploader?Type=Flash' ;

FCKConfig.ImageUploadURL = FCKConfig.BasePath + 'filemanager/upload/simpleuploader?Type=Image' ;

4.就到页面了
先导入js, :  <script type="text/javascript" src="#{adminAccountBean.contextPath}/fck/fckeditor.js"></script>

在对应的texarea 加上一段代码，只要关注javascript 那段：

 <td class="edit-value">
    
         <h:inputTextarea id="description" styleClass="textbox" value="#{adminJobEditBean.jobRow.description}" />
          <script type="text/javascript">
                     var oFCKeditor = new FCKeditor('jobForm:description') ;    <!--  参数为textarea名字   -->
                     oFCKeditor.BasePath = "#{adminAccountBean.contextPath}/fck/" ;  <!--  fck路径   -->
                     oFCKeditor.Height = 400;
                     oFCKeditor.ToolbarSet = "Default" ;
                     oFCKeditor.ReplaceTextarea();
                  </script>
