sending emails using Servlet

[nikita.chandra]

Hi all,
I am trying to send email using a java class and gmail mail server given below is the code for this but its not working UnknownHostException found.I have replaced all the email addresses with actual email addresses.

import javax.mail.*;

import javax.mail.internet.*;

import java.util.*;

 

public class Mail

{

         String  d_email = "[e-mail]",

            d_password = "****",

           d_host = "smtp.gmail.com",

            d_port  = "465",

            m_to = "[e-mail]",

            m_subject = "Testing",

            m_text = "Hey, this is the testing email using smtp.gmail.com.";

    public static void main(String[] args)

    {

                String[] to={"[e-mail]"};

                String[] cc={"[e-mail]"};

                String[] bcc={"[e-mail]"};

                //This is for google

                        Mail.sendMail("[e-mail]","password","smtp.gmail.com","465","true",

"true",true,"javax.net.ssl.SSLSocketFactory","false",to,cc,bcc,

"hi baba don't send virus mails..","This is my style...of reply..

If u send virus mails..");             

    }

 

        public synchronized static boolean sendMail(String userName,String passWord,String host,String port,String starttls,String auth,boolean debug,String socketFactoryClass,String fallback,String[] to,String[] cc,String[] bcc,String subject,String text){

                Properties props = new Properties();

                //Properties props=System.getProperties();

        props.put("mail.smtp.user", userName);

        props.put("mail.smtp.host", host);

                if(!"".equals(port))

        props.put("mail.smtp.port", port);

                if(!"".equals(starttls))

        props.put("mail.smtp.starttls.enable",starttls);
#
        props.put("mail.smtp.auth", auth);

                if(debug){

                props.put("mail.smtp.debug", "true");

                }else{

                props.put("mail.smtp.debug", "false");         

                }

                if(!"".equals(port))

        props.put("mail.smtp.socketFactory.port", port);

                if(!"".equals(socketFactoryClass))

        props.put("mail.smtp.socketFactory.class",socketFactoryClass);

                if(!"".equals(fallback))

        props.put("mail.smtp.socketFactory.fallback", fallback);

 

        try

        {

                        Session session = Session.getDefaultInstance(props, null);

            session.setDebug(debug);

            MimeMessage msg = new MimeMessage(session);

            msg.setText(text);

            msg.setSubject(subject);

            msg.setFrom(new InternetAddress("[e-mail]"));

                        for(int i=0;i<to.length;i++){

            msg.addRecipient(Message.RecipientType.TO, new InternetAddress(to[i]));

                        }

                        for(int i=0;i<cc.length;i++){

            msg.addRecipient(Message.RecipientType.CC, new InternetAddress(cc[i]));

                        }

                        for(int i=0;i<bcc.length;i++){

            msg.addRecipient(Message.RecipientType.BCC, new InternetAddress(bcc[i]));

                        }

            msg.saveChanges();

                        Transport transport = session.getTransport("smtp");

                        transport.connect(host, userName, passWord);

                        transport.sendMessage(msg, msg.getAllRecipients());

                        transport.close();

                        return true;

       }

        catch (Exception mex)

        {

            mex.printStackTrace();

                        return false;

        }

        }

 

}

I think that some changes is required here but unable to understand as i have never used this before.

Thanks in advance
