JavaMail 发送验证邮件(JSP/Servlet实例源码)
转载自 bladecrazy最终编辑 bladecrazy● 发送email：包括文本邮件、HTML邮件、带附件的邮件、SMTP验证
● 接收email：pop3远程连接、收取不同MIME的邮件、处理附件
首先需要配置环境。需要mail.jar和activation.jar两个包。地址在java.sun.com上，很容易找到。放到classpath中，比如我的是这样.;E:\Tomcat5\common\lib\activation.jar;E:\Tomcat5\common\lib\mail.jar;E: \Tomcat5\common\lib\mailapi.jar;E:\Tomcat5\common\lib\;E:\jdk1.5\lib\dt.jar; E:\jdk1.5\lib\tool.jar;E:\jdk1.5\lib\;E:\jdk1.5\bin\;E:\jdk1.5。
