先去下載一個(gè)FCKeditor，再下一個(gè)FCKeditor.java 2.3 (FCKeditot for java) 這個(gè)文件就是用來(lái)讓它支持JSP的，我找了FCKeditor的官網(wǎng)，不過(guò)下載地址好像不大好用，建議去http://sourceforge.net/下載。網(wǎng)上說(shuō)還有一個(gè)東西要下，就是xalan.jar，xml.apache.org是它的網(wǎng)站。

現(xiàn)在開(kāi)始設(shè)置，先到tomcat->webapps里建立一個(gè)文件夾叫mysite。把FCKeditor里的/editor和fckconfig.js, fckeditor.js, fckstyles.xml, fcktemplates.xml四個(gè)文件copy到mysite文件夾里，因?yàn)閯e的文件對(duì)我們來(lái)說(shuō)沒(méi)有什么意義。再把FCKeditor.java 2.3中的web目錄下的WEB-INF目錄copy到mysite下(里面有commons-fileupload.jar, FCKeditor-2.3.jar,web.xml等幾個(gè)文件), 把其中的src目錄下的FCKeditor.tld文件copy到mysite/WEB-INF/下.這樣它才支持JSP。

下面我們要對(duì)其中的一些文件進(jìn)行修改：
打開(kāi)fckconfig.js 文件，修改 FCKConfig.DefaultLanguage = 'zh-cn' ;
把FCKConfig.LinkBrowserURL等的值替換成以下內(nèi)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' ;

打開(kāi)WEB-INF下面的web.xml文件：
把SimpleUploader中的配置屬性enabled定義為true(開(kāi)啟文件上傳功能)
添加標(biāo)簽定義:
<taglib>
<taglib-uri>/mysite</taglib-uri>
<taglib-location>/WEB-INF/FCKeditor.tld</taglib-location>
</taglib>

這樣文件就設(shè)置完了,這時(shí)建立一個(gè)jsp文件試試：
<%@ page contentType="text/html; charset=gb2312" language="java" import="java.sql.*" import="java.util.*" import="java.text.*" errorPage="" %>
<%@ page language="java" import="com.fredck.FCKeditor.*" %>
<%@ taglib uri="/mysite" prefix="FCK" %>
<script type="text/javascript" src="/mysite/fckeditor.js"></script>
<form method="POST" action="Bs_Bulletin_save.jsp">
<table width="100%" border="0" cellspacing="1" cellpadding="2">
　　<tr>
<td width="19%" bgcolor="#F0F0F0" height="25" align="right">標(biāo)題：</td>
<td width="81%" bgcolor="#F0F0F0"><INPUT TYPE="text" NAME="title" size="58"></td>
</tr>
<tr>
<td width="19%" height="300" bgcolor="#F0F0F0">
<div align="center">中文信息設(shè)置<BR><BR>
<span style="color: #FF0000">支持html（圖片大小寬度不要超過(guò)170個(gè)象素）</span></div>
</td>
<td width="81%" bgcolor="#F0F0F0">
<textarea name="content" cols="58" rows="15"></textarea>
<script type="text/javascript">
var oFCKeditor = new FCKeditor('content') ;
oFCKeditor.BasePath = "/mysite/" ;
oFCKeditor.Height = 400;
oFCKeditor.ToolbarSet = "Default" ;
oFCKeditor.ReplaceTextarea();
</script>
</td>
</tr>
<tr>
<td width="19%" height="25" bgcolor="#F0F0F0">發(fā)布時(shí)間：</td>
<td width="81%" bgcolor="#F0F0F0"><INPUT TYPE="text" NAME="datatimes" value="<%=time%>" size="58"></td>
</tr>

<tr>
<td colspan="2" bgcolor="#F0F0F0">
<div align="center"><input type="submit" value=" 添　加 " name="cmdok">&nbsp;<input type="reset" value=" 重 寫(xiě) " name="cmdcancel"></div></td>
</tr>
</table>
</form>

加紅字的部分，就是調(diào)用這個(gè)在線編輯器了。現(xiàn)在上傳的圖看一下，提示internal server error 500，還記得一開(kāi)始時(shí)，我們提到的xalan.jar嗎，現(xiàn)在把xalan.jar放到lib文件夾里，關(guān)掉tomcat再重起一下，應(yīng)該好用了……

注意，如果想把這個(gè)控件融入你現(xiàn)有的web應(yīng)用系統(tǒng)中，就不需要新建mysite了，你可以這樣做：

１、把FCKeditor里的/editor和fckconfig.js, fckeditor.js, fckstyles.xml, fcktemplates.xml四個(gè)文件直接copy到現(xiàn)有web應(yīng)用的某個(gè)目錄下。

２、把FCKeditor.java 2.3中WEB-INF目錄里的commons-fileupload.jar, FCKeditor-2.3.jar放在現(xiàn)有系統(tǒng)的lib目錄下。

３、在現(xiàn)有系統(tǒng)的web.xml中加入FCKeditor.java 2.3中web.xml的配置信息，并添加標(biāo)簽定義:
<taglib>
<taglib-uri>/mysite</taglib-uri>
<taglib-location>/WEB-INF/FCKeditor.tld</taglib-location>
</taglib>
這里別忘了把SimpleUploader中的配置屬性enabled定義為true以開(kāi)啟文件上傳功能！

４、然后把FCKeditor.tld文件copy到現(xiàn)有系統(tǒng)的WEB-INF/下，這樣就可以了。當(dāng)然，F(xiàn)CKeditor.tld的位置不是絕對(duì)的，你可以放在其它地方，只要在前面的標(biāo)簽定義中指定相應(yīng)的位置就行了。
