内容为HTML网页的邮件叫做HTML型邮件，它与文本型邮件的主要区别在于MIME类型的不同，一个为“text/html”，一个为“text/plain”。本文将使用javaMail发送HTML型邮件。用户通过在邮件书写页面attachMail.jsp填写表单然后提交给sendMail.jsp，，由sendMail.jsp调用实体bean实现邮件的发送。。
attachMail.jsp：
<%@ page language="java" import="java.util.*" pageEncoding="gb2312"%>
<%
String path =request.getContextPath();
String basePath =request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
