hirondelle.web4j.webmaster.Emailer

Send a simple email from the webmaster to a list of receivers.

See {@link hirondelle.web4j.BuildImpl} for important information on how this item is configured. {@link hirondelle.web4j.BuildImpl#forEmailer()} returns the configured implementation of this interface.

Implementations of this interface will be called by the framework when it needs to send an email. For example, {@link TroubleTicket} uses such an implementation to send diagnostic information to the webmaster. The from-address is taken from the webmaster email configured in web.xml.

Sending Email on a Separate Thread
Sending an email can be slow. It is often helpful to relegate that task to a worker thread, to improve response times. However, many containers restrict or prohibit creation of threads by a servlet.

The {@link EmailerImpl} default implementation of this interface allows the option of sending email either with or without a separate worker thread. See web.xml in the example application for more details.

      fLogger.fine("Sending email for password reset. Sending to : "  + user.getEmailAddress());
      String nonce = buildNonceFor(user);
      //technically should be done in a tx, but the likelihood of error is nearly zero.
      dao.setNewNonce(user, nonce);
      
      Emailer emailer = BuildImpl.forEmailer();
      List<String> toEndUser = new ArrayList<String>();
      toEndUser.add(user.getEmailAddress());
      emailer.sendFromWebmaster(toEndUser, buildEmailSubject(user), buildEmailBody(user, nonce));
      addMessage("An email has been sent to that email address. The email contains a special link to let you reset your password.");
    }
