我是这样实现FCKeditor_2.4.2

      
经过数天调试，终于在seam中成功实现 FCKeditor_2.4.2。
        FCKeditor的上传目录为相对于web根目录的一个临时目录，每次jboss重启，临时目录都要改名，导致原先上传文件全部丢失，通过修改ConnectorServlet.java，实现了在web.xml中指定上传文件绝对路径，解决了上传文件保存问题。
        我的环境：winxp,jboss4.0.5,seam1.1.6,jboss-ide2.0

1、“FCKeditor”目录放置于view目录下。

2、修改“/FCKeditor/fckeditor.js”(以下2-8条摘自http://lingoosoft.blog.ccidnet.com/blog/ccid/do_showone/tid_139643.html)
将其中：
this.BasePath            = '/fckeditor/' ;
改为：
this.BasePath            = '/FCKeditor/' ;

3、修改“/FCKeditor/fckconfig.js”
将其中：
var _FileBrowserLanguage      = 'asp' ;
var _QuickUploadLanguage      = 'asp' ;
改为：
var _FileBrowserLanguage      = 'jsp' ;
var _QuickUploadLanguage      = 'jsp' ;

4、在SimpleUploaderServlet.java的约第113行附近，加入下面代码，避免构建null路径

if (typeStr==null || typeStr.trim().equals("")) typeStr = "File";
（这个是仿照fckeditor在upload.php,upload.asp等源码来修改的）

5、修改fck-faces-1.7.26.jar源码，在Servlet.java中加入如下代码：
（此代码解决了上传文件无响应的问题）
public void doPost(HttpServletRequest request, HttpServletResponse response)
           throws ServletException, IOException {
     doGet(request, response);
}

6、在FCKFaceEditorTag.java中加入处理编辑器宽和高的代码：
修改下面方法
protected void setProperties(UIComponent component) {
  super.setProperties(component);
  Tags.setString(component, "toolbarSet", toolbarSet);
}
为：
protected void setProperties(UIComponent component) {
  super.setProperties(component);
  Tags.setString(component, "toolbarSet", toolbarSet);
  Tags.setString(component, "height", height);
  Tags.setString(component, "width", width);
}

7、修改 org.fckfaces.component.html.FCKFaceEditor的saveState(FacesContext context)和restoreState(FacesContext context, Object state)方法，来保存和恢复宽和高的属性。
public Object saveState(FacesContext context) {
  Object values[] = new Object[4];
  values[0] = super.saveState(context);
  values[1] = height;
  values[2] = width;
  values[3] = toolbarSet;
  return ((Object) (values));
}

public void restoreState(FacesContext context, Object state) {
  Object values[] = (Object[])(Object[])state;
  super.restoreState(context, values[0]);
  System.out.println(values.length);
  height = (String)values[1];
  width = (String)values[2];
  toolbarSet = (String)values[3];
}

8、web.xml中的配置

}
通过取消String realBaseDir=getServletContext().getRealPath(baseDir);
使用File baseFile=new File(baseDir)，定义绝对路径。
这样，在web.xml中，即可直接指定绝对路径
<param-name>baseDir</param-name>
<param-value>C://fckUpload/</param-value>

10、根据web.xml中的参数
      <servlet-name>Connector</servlet-name>
      <url-pattern>/FCKeditor/editor/filemanager/browser/default/connectors/jsp/connector.jsp</url-pattern>
需要手工建立对应的文件夹，文件connector.jsp由test.html改名即可。

用同样方法修改
      <servlet-name>SimpleUploader</servlet-name>
      <url-pattern>/FCKeditor/editor/filemanager/upload/upload.jsp</url-pattern>
对应的文件夹和文件。
