按以下方式调mySmartUpload的方法即可<%@page contentType="text/html;charset=gb2312"%> <%@ page language="java" import="com.htyz.fileUtil.*"%> <jsp:useBean id="mySmartUpload" scope="page" class="com.htyz.fileUtil.UploadFiles" /><HTML> <BODY BGCOLOR="white"> <% // Variables int count=0; // Initialization mySmartUpload.initialize(pageContext); // Upload mySmartUpload.upload(); try { // Save the files with their original names in the virtual path "/upload" // if it doesn't exist try to save in the physical path "/upload" count = mySmartUpload.save("/elearning/news/upload/");
//filename="http://"+"/upload/mysmartUpload.getFieldName()" // Save the files with their original names in the virtual path "/upload" // count = mySmartUpload.save("/upload", mySmartUpload.SAVE_VIRTUAL); // Display the number of files uploaded out.println(count + " file(s) uploaded."); } catch (Exception e) { out.println(e.toString()); }
有没有说明什么的。
jspsmartupload是不是得注册啊？
不注册是不是有时间限制啊？

我是刚开始接触这儿，
因此不明白，呵呵。
那个Apache + Jserv 要运行JSP是不是得再安装gnujsp啊？
没有那个文件是不是还不能解析JSP？
还有yuanyifileup是不是存成yuanyifileup.class放到servlets目录下？
最好给我一个例子！
我是对这个一点也不明白哦.......
真是伤心
