我想从我的 jsp 页面发送电子邮件。我正在使用 Apache Tomcat 服务器并在本地主机上运行。我提到了这个链接 http://www.javabeat.net/send-mail-jsp/指导我。我还在 JangoSMTP 上创建了一个帐户，并在下面的代码中提供了用户名和密码。但是，我得到的错误是:
An error occurred at line: 24 in the jsp file: /index2.jsp
Session cannot be resolved to a type
21: props.put("mail.smtp.port", "25");
22:
23: //Get the Session object.
24: Session mailSession = Session.getInstance(props,
25: new javax.mail.Authenticator() {
26: protected PasswordAuthentication getPasswordAuthentication() {
27: return new PasswordAuthentication(username,
这是我的 index.html:-

String result;

String to = "xyz@gmail.com";
// Sender's email ID needs to be mentioned
String from = "abc@gmail.com";
final String username = "username";
final String password = "password";
// Assuming you are sending email through relay.jangosmtp.net
String host = "relay.jangosmtp.net";
Properties props = new Properties();
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.host", host);
props.put("mail.smtp.port", "25");
//Get the Session object.
Session mailSession = Session.getInstance(props,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username,
password);
}
});
try {
// Create a default MimeMessage object.
Message message = new MimeMessage(mailSession);
// Set From: header field of the header.
message.setFrom(new InternetAddress(from));
// Set To: header field of the header.
message.setRecipients(Message.RecipientType.TO,
InternetAddress.parse(to));
// Set Subject: header field
message.setSubject("Testing Subject");
// Now set the actual message
message.setText("Hello, this is sample for to check send "
+ "email using JavaMailAPI in JSP ");
// Send message
Transport.send(message);
System.out.println("Sent message successfully....");
result = "Sent message successfully....";
} catch (MessagingException e) {
e.printStackTrace();
result = "Error: unable to send message....";
