Envio de email com javamail e gmail

Front-end
#1

Ola turma, estou tentando criar uma classe responsavel por enviar emails e estou utilizando a ultima versao do javamail.


import java.security.Security;
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.InternetAddress;
import javax.mail.internet.MimeMessage;
 
public class SendMail {
 
    private static final String SMTP_HOST_NAME = "smtp.gmail.com";
    private static final String SMTP_PORT = "465";
    private static final String emailMsgTxt = "Test Message Contents";
    private static final String emailSubjectTxt = "A test from gmail";
    private static final String emailFromAddress = "### LOGIN ###@gmail.com";
    private static final String SSL_FACTORY = "javax.net.ssl.SSLSocketFactory";
    private static final String[] sendTo = { "### LOGIN ###@gmail.com"};
    
    
    public static void main(String args[]) throws Exception {
 
        Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
        new SendMail().sendSSLMessage(sendTo, emailSubjectTxt,emailMsgTxt, emailFromAddress);
        System.out.println("Sucessfully Sent mail to All Users");
    }
 
    public void sendSSLMessage(String recipients[], String subject,
            String message, String from) throws MessagingException {
        boolean debug = true;
 
        Properties props = new Properties();
        props.put("mail.smtp.host", SMTP_HOST_NAME);
        props.put("mail.smtp.auth", "true");
        props.put("mail.debug", "true");
        props.put("mail.smtp.port", SMTP_PORT);
        props.put("mail.smtp.socketFactory.port", SMTP_PORT);
        props.put("mail.smtp.socketFactory.class", SSL_FACTORY);
        props.put("mail.smtp.socketFactory.fallback", "false");
 
        Session session = Session.getDefaultInstance(props,
                new javax.mail.Authenticator() {
 
                    protected PasswordAuthentication getPasswordAuthentication() {
                        return new PasswordAuthentication("### LOGIN ###", "### SENHA ###");
                    }
                });
 
        session.setDebug(debug);
 
        Message msg = new MimeMessage(session);
        InternetAddress addressFrom = new InternetAddress(from);
        msg.setFrom(addressFrom);
 
        InternetAddress[] addressTo = new InternetAddress[recipients.length];
        for (int i = 0; i < recipients.length; i++) {
            addressTo[i] = new InternetAddress(recipients[i]);
        }
        msg.setRecipients(Message.RecipientType.TO, addressTo);
 
        // Setting the Subject and Content Type
        msg.setSubject(subject);
        msg.setContent(message, "text/plain");
        Transport.send(msg);
    }
}

so que toda vez que e ele tenta enviar retornar o erro:

Meu modelo de envio com o gmail é o Seguinte :

Tem que ter as Bibliotecas mail.jar , activation.jar

[code]Essa é a Página de Recepção do FORM que encaminha os dados pro SERVLET e obtem o retorno se foi enviada ou não .

<%@ page contentType="text/html; charset=ISO-8859-1" %> <% 
        try {
           
            String assunto = "Sugestões e Críticas ::: Ifranca";

            String de = request.getParameter("email_email");
            String Usuario = request.getParameter("nome_email");
            String Email = request.getParameter("email_email");
            String mensagem =  request.getParameter("mensagem_email");

Espero que tenha ajudado , este é o código que eu uso no meu site … sou iniciante ainda mas já aprendi um pouquinho pelo menos

#3

cara eu copiei seu codigo trocando apenas os emails e continua dando o mesmo erro:

exception

javax.servlet.ServletException: Sending failed;
nested exception is:

#4

Você habilitou o pop no Gmail ?talvez seja isso
ou talvez esteja faltando alguma biblioteca ,
verifica isso

#5

Tente colocar essa string como seu host_smtp: gmail-smtp.l.google.com
E verifique as bibliotecas activation e mail se estão no projeto.
