<p>I have successfully sent email in my web application using JMS, but the result only displays in plain text. I want the content to be able to display html. How do I do it? Here is roughly what I have:</p>
<pre><code>Message msg = new MimeMessage(mailSession);
try{
    msg.setSubject(&quot;Test Notification&quot;);
    msg.setRecipient(Message.RecipientType.TO, new InternetAddress(sentTo, false));
    String message = &quot;&lt;div style=\&quot;color:red;\&quot;&gt;BRIDGEYE&lt;/div&gt;&quot;;
    msg.setText(message);
    msg.setSentDate(new Date());
    Transport.send(msg);
}catch(MessagingException me){
    logger.log(Level.SEVERE, &quot;sendEmailNotification: {0}&quot;, me.getMessage());
}
</code></pre>


How do I send an HTML email?

我已经使用JMS在我的web应用程序中成功地发送了电子邮件，但结果仅以纯文本显示。我希望内容能够显示html。我该怎么做呢？下面是我所掌握的大致情况：Message msg = new MimeMessage(mailSession);try{    msg.setSubject("Test Notification"...
