jsp的文件怎么上传
1.文件上传：
有关jsp的文件上传，我们需要导一个叫jspsmartupload.jar的包。
例 1.1.1
upload.jsp:
<%@ page contentType="text/html; charset=GBK" %>
<html>
<body>
<h1>
<%
if(request.getParameter("i")!=null)
{
out.print("上传了"+request.getParameter("i")+"个文件");
}
%>
</h1>
we must use post, otheriwse, report negativeArray error.
<form method="post" action="ServletHello2" enctype="multipart/form-data">
<br>
<input type="text" name="user" value="可以中文"/>
<!--the following name does not matter.-->
