jsp中jsp中群发邮件群发邮件
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
jsp中群發郵件 1、獲取需要的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])，將activation.jar和mail.jar復制到應用程序的\WEB-INF\lib中，即可使用。 2、sendmail.jsp文件代碼：
<% @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 電子郵件發送系統</title>

<body> <%

?String from = "";
?String to = "";

?String user = "zyf0808"; // 填寫自己的郵件服務器登錄用戶名

?String subject = connBean.change(request.getParameter("txtSubject")); // 郵件標題
?String body =connBean.change(request.getParameter("txtContent"));// 郵件內容
??? if(userName!=null && !userName.equals(""))
??{
