title: Reading html files for use as email templates
body: <p>I have webpage html templates that I want to use in my java code for sending html email with Java Mail.</p>
  
  <p><code>MimeMessage message = new MimeMessage(session);</code> </p>
  
  <p><code>message.setContent(html, "text/html");</code></p>
  
  <p>I want to use the method <code>message.setContent(html, "text/html");</code>
  I think html has to be a string. How do I get my webpage html templates into a String?</p>
