＜servlet＞
＜servlet-name＞Connector＜/servlet-name＞
＜servlet-class＞com.fredck.FCKeditor.connector.ConnectorServlet＜ /servlet-class＞

＜servlet-mapping＞
＜servlet-name＞SimpleUploader＜/servlet-name＞
＜url-pattern＞/fckeditor/simpleuploader＜/url-pattern＞
＜/servlet-mapping＞
4. Modify /WebRoot/fckeditor/ fckconfig.js, the modified part is as follows:
FCKConfig.LinkBrowserURL = FCKConfig.BasePath + 'filemanager/browser/
default/browser.html?Connector=/fckeditor/connector' ;
FCKConfig.ImageBrowserURL = FCKConfig.BasePath + 'filemanager/browser /
default/browser.html?Type=Image&Connector=/fckeditor/connector' ;
FCKConfig.FlashBrowserURL = FCKConfig.BasePath + 'filemanager/browser/
default/browser.html?Type=Flash&Connector=/fckeditor/connector' ;
FCKConfig.LinkUploadURL = '/fckeditor/simpleuploader?Type=File' ;
FCKConfig.ImageUploadURL = '/fckeditor/simpleuploader?Type=Image' ;
FCKConfig.FlashUploadURL = '/fckeditor/simpleuploader?Type=Flash';
Note:
(1) Steps 3 and 4 set up the configuration of file browsing and uploading. The of the Servlet in web.xml must be consistent with the URL reference in fckconfig.js;
(2) Prerequisites for the normal operation of this example WebRoot is deployed as the root path. If a virtual path is set, the servlet will not be found.
4. Use
This example uses the most direct js method. For API and TagLib methods, please refer to the example under _samples after decompression of FCKeditor-2.3.zip.

＜%@ page contentType="text/html;charset=GBK"%＞

String content=request. getParameter("content");
if (content != null) {
content = content.replaceAll("rn", "");
content = content.replaceAll("r", "");
content = content.replaceAll("n", "");
content = content.replaceAll(""", "'");
}else{
content = "";
}
