一、我们可以通过任何支持sun规范中的sun.net.smtp包的JSP引擎(如JSWDK)发送mail。
(警告:使用内置的internal Sun规范包,这将影响到你的jsp程序的可移植性。)
以下scriptlet利用SmtpClient类在jsp文件中发送email。
二、 JavaMail是官方的 Java mail API,可参考 http://java.sun.com/products/javamail/。虽然该API比 sun.net.smtp.SmtpClient更丰富或者说更复杂,但它是可移植的。这里重新创建了一个 MailSender类,它包含了 JavaMail API。如下所示:
// ms_ prefix is for MailSender class variables
// str prefix is for String
// astr prefix is for array of Strings
// strbuf prefix is for StringBuffers, etc.
public MailSender(
String strFrom, // sender 网管论坛bbs_bitsCN_com
String[] astrTo, // recipient(s)
String[] astrBCC, // bcc recipient(s), optional
String strSubject, // subject
boolean debugging)
{
ms_strFrom = strFrom; // who the message is from
ms_astrTo = astrTo; // who (plural) the message is to
ms_debugging = debugging; // who (plural) the message is to
// set the host
Properties props = new Properties();
props.put(\"mail.smtp.host\", ms_strSMTPHost);
// create some properties and get the default Session
Session session = Session.getDefaultInstance(props, null);
session.setDebug(ms_debugging);
try {
// create a message
ms_msg = new MimeMessage(session);
// set the from

InternetAddress from = new InternetAddress(strFrom);
System.out.println(\"Caught exception in MailSender.ms_send: \" + ex);
}
}
