testing mail with appengine development server (java)

Question

I\'m using javamail to send mails from my appengine application. It works perfectly in the deployment, but I can\'t figure out how to do this using the development server. Whene

Answer 1

You can do the following for setting up email on the development server

final String username = "xxxxxxxxx@gmail.com";//change accordingly
final String password = "xxxxxxx";//change accordingly

// Assuming you are sending email through gmail
String host = "smtp.gmail.com";

Properties props = new Properties();
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.host", host);
props.put("mail.smtp.port", "587");

// Get the Session object.
Session session = Session.getInstance(props,
new javax.mail.Authenticator() {
 protected PasswordAuthentication getPasswordAuthentication() {
    return new PasswordAuthentication(username, password);
 }
});
session.setProtocolForAddress("rfc822", "smtp");

And use the session normally to send emails:

try {
    Message msg = new MimeMessage(session);
    msg.setFrom(new InternetAddress("xxxx@gmail.com", "xxxx"));
    msg.addRecipient(Message.RecipientType.TO,
    new InternetAddress("user@testdomain.com,"Mr. User"));
    msg.setSubject("Test email from GAE/J development");
    msg.setText("This is test:);
    Transport.send(msg);

} catch (Exception e) {
    e.printStackTrace();
}

Additionally you need to add the following two libraries in build path and under war/WEB-INF/lib:

• javax.mail.jar
• javax.activation.jar

You can find the links easily by googling them.

Finally if you want to use gmail as the smtp server, you need to go to your account, and enable access for less seucre apps https://www.google.com/settings/security/lesssecureapps
