Transport.send problem

[Harry Jones]

I send an email once in a while from my web application on a virtual dedicated server. Usually the email works. But sometimes Transport.send hangs up. Processing just stops at that statement. I don't get anything from debug.

Here is the call:

        try {
            SendEmail sendemail = new SendEmail();

            sendemail.SendEmail(toAddress, fromAddress,
                    smtphost, subject, content);
        } catch (Exception e) {
        } finally {
        }

Here is the sendmail:

public class SendEmail {

    public void SendEmail(String toEmailAddress,
            String fromEmailAddress,
            String smtphost, String subject, String content)
            throws AddressException, MessagingException {

        // Create a mail session
        java.util.Properties props = new java.util.Properties();
        props.put("mail.smtp.host", smtphost);
        props.put("mail.debug", "true");

        Session session = Session.getInstance(props, null);

        // Construct the message
        Message msg = new MimeMessage(session);
        msg.setFrom(new InternetAddress(fromEmailAddress;));
        msg.setRecipient(Message.RecipientType.TO, new InternetAddress(toEmailAddress));
        msg.setSubject(subject);
        msg.setText(content);
        // Send the message
        Transport.send(msg);

        return;
    }
}

What could be causing the problem with Transport.send? I researched this but can't find an answer. Thanks.

Don't ignore exceptions like that; at least print its stack trace.

I actually cut this out to keep the post short:

getServletContext().log("servlet: " + getServletName() + "; message: " + e.getMessage(), e);

I would like to use try/catch /finally with the Transport.send, but I don't know how to write to the log from there. Any help would be appreciated.
