JavaMail - Como utilizar

Google is your friend, but GUJ is your BEST friend!

Veja:
Enviando emails com Java

Era só ir na seção Artigos/Tutoriais, apertar Ctrl+F e digitar mail. Violà!

Outro exemplo utilizando a API Commons-email da Jakarta

Falow!

Vendo esse exemplo da API Commons-email da Jakarta, eu fiz aqui mas deu erro.

[color=blue]package CommosEmail;

import org.apache.commons.mail.EmailException;
import org.apache.commons.mail.SimpleEmail;

public class EmailSimples {

/**

 * @throws EmailException

public static void main(String[] args) {
	SimpleEmail email = new SimpleEmail();

	email.setHostName("smtp.gmail.com"); // o servidor SMTP para envio do e-mail

	try {
		email.addTo("[email removido]", "JUNIOR");//destinatário
		email.setFrom("[email removido]", "HEHE"); // remetente

		email.setSubject("Mensagem de Teste"); // assunto do e-mail

		email.setMsg("Teste de Email utilizando commons-email"); //conteudo do e-mail

		email.send(); //envia o e-mail

	} catch (EmailException e) {
		System.err.print(e.getMessage());
	}

Que erro e esse?

Olá!

Falta colocar no seu classpath o arquivo .jar activation.jar que vem na Java Activation Framework (JAF) !

Abraço!

Eu coloquei, esse problema esta resolvido, valeu!!

Mas agora estou tendo problema para configurar o SMTP do gmail que requer autenticação.

Peguei um exemplo aqui, testei mas esta dando erro!

Para o Yahoo:

VI QUE PARA O yahoo DISSERAM QUE PRECISARIA DISSO.

Store store = mailSession.getStore(“pop3”);

store.connect(“pop.mail.yahoo.com.br”, auth.username , auth.password);

Mas ainda não consegui fazer funcionar… Se alguém conseguir, por favor, me digam como!!!

[email removido] :lol:

ola fiz o exemplo acima e funcionou certinho tanto no gmail como no yahoo , so que a forma como se coloca o nome de usuario é diferente no lugar de [email removido] , coloque apenas seuemail sem @yahoo.com.br
vou postar o codigo que fiz apenas alterndo o usuario para enviar pelo smtp do yahoo:

Ola Amigos

Tentei enviar o email pela web e nao consegui e desktpo consigo.

Utilizo netbeans 6 e o glassfish.

Sera que é alguma configuracao que preciso fazer, pois nao exibe nenhum erro.

O codigo segue abaixo:

protected void processRequest(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException ,MalformedURLException
    {
        response.setContentType("text/html;charset=UTF-8");
        PrintWriter out = response.getWriter();
        try 
        {
            String msg= "TESTE";

            SimpleEmail email = new SimpleEmail();
            email.setDebug(true);
            email.setHostName("smtp.gmail.com");
            email.setAuthentication("usuario", "senha");
            email.setSSL(true);
            email.addTo("[email removido]");
            email.setSubject("Teste");
            email.setMsg(msg);
            //email.send();   //Se eu descomentar esta linha, nao sera exibido a saida abaixo "TESTANDO", e independente de eu comentar ou nao, nao é enviado o email.
            
            out.println("<html>");
            out.println("<body>");
            out.println("TESTANDO");
            out.println("</body>");
            out.println("</html>");
        } 
        catch (EmailException ex) {
            Logger.getLogger(ServiceLoginAuth.class.getName()).log(Level.SEVERE, null, ex.getStackTrace()+ex.getMessage());
        } finally { 
            out.close();
        }
    }
