JavaMail发送邮件

1、使用JavaMail发送邮件需要用到mail.jar和activtion.jar两个包。该类实现了较完整的邮件发送功能，包括以HTML格式发送，添加附件和抄送人。下面是具体的代码：Mail.java：Java代码1. packagecn.cgw.util.mail;2. 3. importjava.util.Properties;4. 5. importjavax.activation.DataHandler;6. importjavax.activation.FileDataSource;7. importjavax.mail.Address;8. importjavax.mail.Body
