问从jsp调用java类中的main方法？

EN

YourMainClass.main(new String[] {"some", "arguments"});

Runtime.getRuntime().exec("java -cp /path/to/root com.example.YourMainClass some arguments");

Public Class JavaMAil{
String d_email = "abc@gmail.com",//you email address
        d_password = "XXXX", //your email password
        d_host = "smtp.gmail.com",
        d_port = "465",
        m_to = "xyz@gmail.com    ", // Target email address
        m_subject = "Testing",
        m_text = "Hey, this is a test email.";



public JavaMail() {
    Properties props = new Properties();
    props.put("mail.smtp.user", d_email);
    props.put("mail.smtp.host", d_host);
    props.put("mail.smtp.port", d_port);
    props.put("mail.smtp.starttls.enable", "true");
    props.put("mail.smtp.auth", "true");
    //props.put("mail.smtp.debug", "true");
    props.put("mail.smtp.socketFactory.port", d_port);
    props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
    props.put("mail.smtp.socketFactory.fallback", "false");
    try {
        SMTPAuthenticator auth = new SMTPAuthenticator();
        Session session = Session.getInstance(props, auth);     
        MimeMessage msg = new MimeMessage(session);
        msg.setText(m_text);
        msg.setSubject(m_subject);
        msg.setFrom(new InternetAddress(d_email));
        msg.addRecipient(Message.RecipientType.TO, new InternetAddress(m_to));
        Transport.send(msg);
    } catch (Exception mex) {
        mex.printStackTrace();
    }
}

public static void main(String[] args) {
    JavaMail blah = new JavaMail();
}

private class SMTPAuthenticator extends javax.mail.Authenticator {
    public PasswordAuthentication getPasswordAuthentication() {
        return new PasswordAuthentication(d_email, d_password);
    }
}

**This is my mail.jsp**

And It is jsp it Invokes Main method from the class called JavaMail




<%@ page import="mail.JavaMail" %>
<%
JavaMail obj = new JavaMail();
%>
