Class HtmlEmail

java.lang.Object

org.apache.commons.mail.Email

org.apache.commons.mail.MultiPartEmail

org.apache.commons.mail.HtmlEmail

public class HtmlEmail
extends MultiPartEmail

An HTML multipart email.

This class is used to send HTML formatted email. A text message can also be set for HTML unaware email clients, such as text-based email clients.

This class also inherits from MultiPartEmail, so it is easy to add attachents to the email.

To send an email in HTML, one should create a HtmlEmail, then use the setFrom, addTo, etc. methods. The HTML content can be set with the setHtmlMsg method. The alternate text content can be set with setTextMsg.

Either the text or HTML can be omitted, in which case the "main" part of the multipart becomes whichever is supplied rather than a multipart/alternative.
