send SMTP mail using JavaMail with gmail account

J

jrefactors

I want the Java application to send email using google gmail account.

The following is the output, and it cannot display "sendMail() 3..."
in the following sendMail() method. The program just hangs after
printing "sendMail() 2...", and there is no errors.

output
===============
sendMail()...
sendMail() 2...

Basically it get stucks on line
transport.connect(smtpHost, 465, "gmail account", "gmail password");

----------------------------------------------------------
public void sendMail() throws MessagingException
{
System.out.println("sendMail()...");
Properties props = new Properties();
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.port", "465");

// props.put("mail.smtp.auth", "true");

Session session = Session.getDefaultInstance(props, null);
session.setDebug(false);
MimeMessage message = new MimeMessage(session);
message.setFrom(from);
Iterator itrto = toRecipients.iterator();
while(itrto.hasNext())
{
Object obj = (Address)itrto.next();
if(obj instanceof Address){
message.addRecipient(Message.RecipientType.TO, (Address)obj);
}
}
System.out.println("sendMail() 2...");

message.setSubject(subject);
message.setContent(msgText, "text/plain");

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

//***** GET STUCK HERE!!! ******
transport.connect(smtpHost, 465, "gmail account", "gmail password");

System.out.println("sendMail() 3...");

Transport.send(message);

System.out.println("sendMail() 4...");

}

I uncomment line props.put("mail.smtp.auth", "true");
but it still cannot display sendMail() 3...:

sendMail()...
sendMail() 2...

But it has exception this time:

javax.mail.MessagingException: Could not connect to SMTP host:
smtp.gmail.com, port: 465;
nested exception is:
java.net.ConnectException: Connection timed out: connect
at com.sun.mail.smtp.SMTPTransport.openServer(SMTPTransport.java:867)

at SMTPHandler.sendMail(SMTPHandler.java:145)
at SMTPHandlerTest.main(SMTPHandlerTest.java:33)
Exception in thread "main"

I have no time to try this myself, but you can give it a go and post
back:

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

I was searching Google for advice on Gmail + javamail and found this forum. I tried Gary's code (replacing the x's with appropriate info, of course) and got the following feedback:

Actually, nevermind. The code worked after I removed all the individual protocols from my /Library/Java/Extensions folder. I hadn't realized they were redundant.

Send from different Gmail domain

I'm trying to accessing mail from a different Google main Domain (custom google apps domain i.e. email(at)labs.com

Currently the application is accessing the mail from Gmail and sending it to same mail id

Does anyone know how to change this?

There are two solution for this:

1. You can generate the application specific password by the link given by "friek" i.e "https://accounts.google.com/IssuedAuthSubTokens" and **use the generated application specific password in place your original password**. I have done this and its working

or

2. The reason why the Exception (javax.mail.AuthenticationFailedException: 535-5.7.1 Application-specific password required) is occurring is that you may have activated the 2-step verification of your gmail account. If you use an account in which you do not activate the 2-step verification then you can send the email by you original password. I have also tried this and its working fine.
