百度编辑器UEditor 在J2EE下使用
一、百度编辑器UEditor 下载，最好自定义下载，只取需要的功能，我下载时的版本为：1.2.0
http://ueditor.baidu.com/website/download.html

二、解压到webapp的目录ueditor里


三、修改配置文件 image.html，将默认的上传改为jsp（约97行）

url:'../../server/upload/jsp/imageUp.jsp',   

四、上传的imageUp.jsp有点问题，更改如下：

//保存文件路径
String filePath = "ueditor/server/upload/uploadimages";
String realPath = request.getRealPath("/") + filePath;
String newFileName = "";
//判断路径是否存在，不存在则创建
File dir = new File(realPath);
if(!dir.isDirectory())
    dir.mkdir();

if(ServletFileUpload.isMultipartContent(request)){

    DiskFileItemFactory dff = new DiskFileItemFactory();
    dff.setRepository(dir);
    dff.setSizeThreshold(1024000);
    ServletFileUpload sfu = new ServletFileUpload(dff);
    FileItemIterator fii = sfu.getItemIterator(request);
    String title = "";   //图片标题
    String url = "";    //图片地址
    String fileName = "";
	String state="SUCCESS";
    while(fii.hasNext()){
        FileItemStream fis = fii.next();

        try{
            if(!fis.isFormField() && fis.getName().length()>0){
                fileName = fis.getName();
				Pattern reg=Pattern.compile("[.]jpg|png|jpeg|gif$");
				Matcher matcher=reg.matcher(fileName);
				if(!matcher.find()) {
					state = "文件类型不允许！";
					break;
				}
				newFileName = new Date().getTime()+fileName.substring(fileName.lastIndexOf("."),fileName.length());
                url = realPath+"/"+ newFileName;
                BufferedInputStream in = new BufferedInputStream(fis.openStream());//获得文件输入流
                FileOutputStream a = new FileOutputStream(new File(url));
                BufferedOutputStream output = new BufferedOutputStream(a);
                Streams.copy(in, output, true);//开始把文件写到你指定的上传文件夹                
            }else{
                String fname = fis.getFieldName();
                if(fname.indexOf("pictitle")!=-1){
                    BufferedInputStream in = new BufferedInputStream(fis.openStream());
                    byte c [] = new byte[10];
                    int n = 0;
                    while((n=in.read(c))!=-1){
                        title = new String(c,0,n);
                        break;
                    }
                }
            }

        }catch(Exception e){
            e.printStackTrace();
        }
    }
	title = title.replace("&", "&amp;").replace("'", "&qpos;").replace("\"", "&quot;").replace("<", "&lt;").replace(">", "&gt;");
    response.getWriter().print("{'url':'uploadimages/"+newFileName+"','title':'"+title+"','state':'"+state+"'}");

}
