jsp中jsp中群发邮件群发邮件
jsp中群发邮件
1、获取需要的jar文件，mail.jar( [url]http://java.sun.com/products/javamail/[/url])和activation.jar( [url]http://java.sun.com/products/javabeans/glasgow/jaf.html[/url])，将activation.jar和mail.jar复制到应用程序的\WEB-INF\lib中，即可使用。
2、sendmail.jsp文件代码：
< % @page contentType="text/html;charset=gb2312"%>
<%@ page import="java.sql.*,java.io.*,java.util.*,java.text.*, javax.mail.*, javax.mail.internet.*" %>
<jsp:useBean id="connBean" scope="session" class="opendb.opendb"/><html>
<head>
<title>JavaMail 电子邮件发送系统</title>
</head>
<body>
< % @page contentType="text/html;charset=gb2312"%>
<%@ page import="java.sql.*,java.io.*,java.util.*,java.text.*, javax.mail.*, javax.mail.internet.*" %>
<jsp:useBean id="connBean" scope="session" class="opendb.opendb"/><html>
<head>
<title>JavaMail 电子邮件发送系统</title>
</head>
<body>
