    <p>I'm trying to use javamail in a groovy script to send out an email via gmail. I've looked many places online and have been unable to get it working thus far. The error I'm getting when running my script is:</p> <pre><code>DEBUG SMTP: useEhlo true, useAuth false DEBUG SMTP: trying to connect to host "smtp.gmail.com", port 25, isSSL false Caught: javax.mail.SendFailedException: Send failure (javax.mail.MessagingException: Could not connect to SMTP host: smtp.gmail.com, port: 25 (javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?)) </code></pre> <p>It appears to be trying to use port 25 even though I've specified that it should use port 587. Does anyone know what could be causing this problem, I've used telnet to connect to the smtp server on port 587, and thunderbird uses port 587 with STARTTLS security and is able to successfully send mail using the smtp server. This tells me that it is not a blocked port or connectivity issue. Here is the code I'm using to try and send the email:</p> <pre><code>import javax.mail.* import javax.mail.internet.* private class SMTPAuthenticator extends Authenticator { public PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication('email@gmail.com', 'password'); } } def d_email = "email@gmail.com", d_password = "password", d_host = "smtp.gmail.com", d_port = "587", //465,587 m_to = "email@gmail.com", m_subject = "Testing", m_text = "This is a test." def props = new Properties() props.put("mail.smtp.user", d_email) props.put("mail.smtp.host", d_host) props.put("mail.smtp.port", d_port) props.put("mail.smtp.starttls.enable","true") props.put("mail.smtp.debug", "true"); props.put("mail.smtp.auth", "true") props.put("mail.smtp.socketFactory.port", d_port) props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory") props.put("mail.smtp.socketFactory.fallback", "false") def auth = new SMTPAuthenticator() def session = Session.getInstance(props, auth) session.setDebug(true); def msg = new MimeMessage(session) msg.setText(m_text) msg.setSubject(m_subject) msg.setFrom(new InternetAddress(d_email)) msg.addRecipient(Message.RecipientType.TO, new InternetAddress(m_to)) Transport.send(msg) </code></pre> <p>Any help would be greatly appreciated. Thanks in advance!</p> <p>-Bryan</p>

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
