4.修改web.xml:
把SimpleUploader中的配置屬性enabled定義為true(開啟文件上傳功能）
添加標簽定義:
<taglib>
<taglib-uri>/FCKeditor</taglib-uri>
<taglib-location>/WEB-INF/FCKeditor.tld</taglib-location>
</taglib>

5.解壓FCKeditor2.2后，把目錄/editor和fckconfig.js, fckeditor.js, fckstyles.xml, fcktemplates.xml四個文件copy到/FCKeditor下
刪除目錄/editor/_source,
刪除/editor/filemanager/browser/default/connectors/下的所有文件
刪除/editor/filemanager/upload/下的所有文件
刪除/editor/lang/下的除了fcklanguagemanager.js, en.js, zh.js, zh-cn.js四個文件的所有文件

6.打開/FCKeditor/fckconfig.js
修改 FCKConfig.DefaultLanguage = 'zh-cn' ;
把FCKConfig.LinkBrowserURL等的值替換成以下內容：
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' ;

7.添加文件 /FCKeditor/test.jsp:
<%@ page language="java" import="com.fredck.FCKeditor.*" %>
<%@ taglib uri="/FCKeditor" prefix="FCK" %>
<script type="text/javascript" src="/FCKeditor/fckeditor.js"></script>

<%--
三種方法調用FCKeditor
1.FCKeditor自定義標簽 (必須加頭文件 <%@ taglib uri="/FCKeditor" prefix="FCK" %> )
2.script腳本語言調用 (必須引用 腳本文件 <script type="text/javascript" src="/FCKeditor/fckeditor.js"></script> )
3.FCKeditor API 調用 (必須加頭文件 <%@ page language="java" import="com.fredck.FCKeditor.*" %> )

<form action="show.jsp" method="post" target="_blank">
<FCK:editor id="content" basePath="/FCKeditor/" width="700" height="500" skinPath="/FCKeditor/editor/skins/silver/"
???toolbarSet = "Default" >
input
</FCK:editor>
<input type="submit" value="Submit">
</form>
--%>

<form action="show.jsp" method="post" target="_blank">
<table border="0" width="700"><tr><td>
<textarea id="content" name="content" style="WIDTH: 100%; HEIGHT: 400px">input</textarea>
<script type="text/javascript">
var oFCKeditor = new FCKeditor('content') ;
oFCKeditor.BasePath = "/FCKeditor/" ;
oFCKeditor.Height = 400;
oFCKeditor.ToolbarSet = "Default" ;
oFCKeditor.ReplaceTextarea();
</script>
<input type="submit" value="Submit">
</td></tr></table>
</form>

<%--
<form action="show.jsp" method="post" target="_blank">
<%
FCKeditor oFCKeditor ;
oFCKeditor = new FCKeditor( request, "content" ) ;
oFCKeditor.setBasePath( "/FCKeditor/" ) ;
oFCKeditor.setValue( "input" );
out.println( oFCKeditor.create() ) ;
%>
<br>
<input type="submit" value="Submit">
</form>
--%>

添加文件/FCKeditor/show.jsp:
<%
String content = request.getParameter("content");
out.print(content);
%>

8.瀏覽 http://localhost:8080/FCKeditor/test.jsp
ok!

9.上傳遇到錯誤: internal server error 500,
直接引用servlet(com.fredck.FCKeditor.connector.ConnectorServlet)也遇到錯誤: "Provider org.apache.xalan.processor.TransformerFactoryImpl not found",
拷貝xalan.jar到lib目錄就可以了
