Hello,

I am using the below code and despite multiple attempts the email is not being shown in "html" format but is always being showing as plain text format:

Output of the above code (<h1> tag is not getting parsed and is being displayed as a plain text): <h1> test email </h1>

Also tried the following options but none of them actually worked:

Same problem with this approach as well:
message.setContent(msgData, "text/html; charset=utf-8");

MimeBodyPart htmlPart = new MimeBodyPart();
String htmlContent = "<html><h1>Hi</h1><p>Nice to meet you!</p></html>";
htmlPart.setContent(htmlContent, "text/html");

Any advice on this will be greatly appreciated.

Start with the JavaMail FAQ page from Oracle. One of the questions there is "How do I send HTML mail?" which seems like a good start for your search.

I tried the oracle mail api that you mentioned but still I am seeing the same issue, that the <html> is being displayed in the form of plain text itself and pasting the logs below:

And no matter what e-mail address you send that message to, and no matter what e-mail client you use to read it, the same thing happens?

It might be that you are missing the Content-Type: text/html header.

How are you testing this?
Essentially Paul's question...does this happen on a number of different email recipients, including different hosts, applications, etc.

Hi Paul,

Yes, no matter to whom I send the email or irrespective of the email clients, I am seeing the same issue.

Thanks.

You need to use the MimeBodyPart and MimeMultipart for the email body to control whether it's plain text or html or whatever. The UTF-8 encoding can also be set.

------=_Part_0_735891530.1465314350219
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 7bit

some body

Rahul -- what email client are you using and on what platform?

Well .. I just took your original code, changed the SMTP host and the To/From addresses, and ran it. Using Outlook, I did see the HTML rendered (even when the HTML wasn't a proper document).

import java.util.Properties;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

public class Mailer {
	public static void main(String[] args) {
		new Mailer().run();
	}
	
	private void run() {
		Properties props = new Properties();
		MimeMessage message = null;
		 
		//TODO: Retrieve this information from PRODPERTIES file
		props.put("mail.smtp.host", "192.168.100.248");
		props.setProperty("mail.transport.protocol", "smtp");
		 
		Session session = Session.getDefaultInstance(props, null);
		message = new MimeMessage(session);
		 
		try {
			// Set From: header field of the header.
			message.setFrom(new InternetAddress("ron@xxxxxxxx.com"));
			message.setSubject("TEST");
			message.addRecipient(Message.RecipientType.TO, new InternetAddress("ron@xxxxxxxx.com"));
			message.setText("<h1> test email </h1>", "utf-8", "html");
			message.saveChanges();
			 
			// Send message
			Transport.send(message);
		} catch (MessagingException e) {
			e.printStackTrace();
		}
	}
}

My email server is sendmail 8.13; client is MS Outlook 14.0 (part of Office 2010).

Thank you. Fixing the different MAIL related jar file in the classpath helped to fix the issue.

Which mail jar you used to resolve this issue. I am facing the same issue with javax.mail

In my case it was due to https://issues.apache.org/jira/browse/GERONIMO-6536. So excluded Geronimo library to fix it.
