Struts 2 Sending Mails

In this chapter we will teach you how to send an email using your Struts 2 application. For this application, you need to download and install the mail.jar from JavaMail API 1.4.7 and place the mail.jar file in your WEB-INF\lib folder and then proceed to follow the standard steps of creating action, view and configuration files.

Create Action:
The next step is to create an Action method that takes care of sending the email. Let us create a new class called MailAction.java with the following contents.

package com.dineshonjava.struts2.mail.action;

import java.util.Properties;
import javax.mail.Message;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

import com.opensymphony.xwork2.ActionSupport;

public class MailAction extends ActionSupport {

 private static final long serialVersionUID = 1L;
 private String from;
    private String password;
    private String to;
    private String subject;
    private String body;

    static Properties properties = new Properties();
    static
    {
       properties.put("mail.smtp.host", "smtp.gmail.com");
       properties.put("mail.smtp.socketFactory.port", "465");
       properties.put("mail.smtp.socketFactory.class",
                      "javax.net.ssl.SSLSocketFactory");
       properties.put("mail.smtp.auth", "true");
       properties.put("mail.smtp.port", "465");
    }

    public String execute() 
    {
       String ret = SUCCESS;
       try
       {
          Session session = Session.getDefaultInstance(properties,  
             new javax.mail.Authenticator() {
              protected PasswordAuthentication 
              getPasswordAuthentication() {
              return new 
              PasswordAuthentication(from, password);
             }});

          Message message = new MimeMessage(session);
          message.setFrom(new InternetAddress(from));
          message.setRecipients(Message.RecipientType.TO, 
             InternetAddress.parse(to));
          message.setSubject(subject);
          message.setText(body);
          Transport.send(message);
       }
       catch(Exception e)
       {
          ret = ERROR;
          e.printStackTrace();
       }
       return ret;
    }

    public String getFrom() {
       return from;
    }

    public void setFrom(String from) {
       this.from = from;
    }

    public String getPassword() {
       return password;
    }

    public void setPassword(String password) {
       this.password = password;
    }

    public String getTo() {
       return to;
    }

    public void setTo(String to) {
       this.to = to;
    }

    public String getSubject() {
       return subject;
    }

    public void setSubject(String subject) {
       this.subject = subject;
    }

    public String getBody() {
       return body;
    }

    public void setBody(String body) {
       this.body = body;
    }

    public static Properties getProperties() {
       return properties;
    }

    public static void setProperties(Properties properties) {
     MailAction.properties = properties;
    }
