Question

我正在尝试在jsp页面上调用java函数。该功能应该按需发送邮件。

这是java代码：

package s;

import java.io.UnsupportedEncodingException;
import java.util.Properties;

import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.AddressException;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

        public class SendMail {

            public static void send() {

                final String username = "";
                final String password = "";

                Properties props = new Properties();
                props.put("mail.smtp.starttls.enable", "true");
                props.put("mail.smtp.auth", "true");
                props.put("mail.smtp.host", "smtp.gmail.com");
                props.put("mail.smtp.port", "587");

                Session session = Session.getInstance(props,
                  new javax.mail.Authenticator() {
                    protected PasswordAuthentication getPasswordAuthentication() {
                        return new PasswordAuthentication(username, password);
                    }
                  });

                try {

                    Message message = new MimeMessage(session);
                    message.setFrom(new InternetAddress("shov.rz@gmail.com"));
                    message.setRecipients(Message.RecipientType.TO,
                        InternetAddress.parse("shov.rz@gmail.com"));
                    message.setSubject("Testing Subject");
                    message.setText("Dear Mail Crawler,"
                        + "\n\n No spam to my email, please!");

                    Transport.send(message);

                    System.out.println("Done");

                } catch (MessagingException e) {
                    throw new RuntimeException(e);
                }
            }

    }

我正在jsp页面上调用它：

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
    <%@import page="s.SendMail"%>
    <%
    s.SendMail.send();
    %>
    <html>
<head>
</head>
</html>

它没有编译，eclipse抛出异常：org.apache.jasper.JasperException 我究竟做错了什么？谢谢你的帮助！

“页面”和“导入”术语是错误的方式。应该是：

    <%@ page import="s.SendMail" %>

从jsp文件调用java函数
