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(SMTPTra nsport.java:867)

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



any ideas? thanks!!

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");

OK Here is working code. I followed the instructions here, which, though it
does not even mention SMTP, still works with SMTP:

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:

What is it I'm doing wrong?

[theAmerican]

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.
