You don't need to learn a whole new templating language to use Seam Mailan email is just facelet!

<m:message xmlns="http://www.w3.org/1999/xhtml"
    xmlns:m="http://jboss.com/products/seam/mail"
    xmlns:h="http://java.sun.com/jsf/html">
  
    <m:from name="Peter" address="peter@example.com" />
    <m:to name="#{person.firstname} #{person.lastname}">#{person.address}</m:to>
    <m:subject>Try out Seam!</m:subject>
    
    <m:body>
        <p><h:outputText value="Dear #{person.firstname}" />,</p>
        <p>You can try out Seam by visiting 
        <a href="http://labs.jboss.com/jbossseam">http://labs.jboss.com/jbossseam</a>.</p>
        <p>Regards,</p>
        <p>Peter</p>
    </m:body>
    
</m:message>

The <m:message> tag wraps the whole message, and tells Seam to start rendering an email. Inside the <m:message> tag we use an <m:from> tag to set who the message is from, a <m:to> tag to specify a sender (notice how we use EL as we would in a normal facelet), and a <m:subject> tag.

The <m:body> tag wraps the body of the email. You can use regular HTML tags inside the body as well as JSF components.

So, now you have your email template, how do you go about sending it? Well, at the end of rendering the m:message the mailSession is called to send the email, so all you have to do is ask Seam to render the view:

@In(create=true)
private Renderer renderer;
   
public void send() {
    try {
       renderer.render("/simple.xhtml");
       facesMessages.add("Email sent successfully");
   } 
   catch (Exception e) {
       facesMessages.add("Email sending failed: " + e.getMessage());
   }
}

If, for example, you entered an invalid email address, then an exception would be thrown, which is caught and then displayed to the user.
