[Scala] GAE/JのMailサービス

本文は普通に日本語文章を与えたらOK。サブジェクトだけ自分でいじることにしました。

import java.util.Properties;

import javax.mail.Message;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.MessagingException;
import javax.mail.internet.AddressException;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeUtility;

class sendmail(strFrom:String) {

 var props:Properties = new Properties();
 var session:Session = Session.getDefaultInstance(props, null);

  def send(strTo:String, strSubject:String, strBody:String) {
  try {
         var msg:Message = new MimeMessage(session);
         msg.setFrom(new InternetAddress(strFrom));
         msg.addRecipient(Message.RecipientType.TO,
                          new InternetAddress(strTo, "Mr. User"));

         msg.setSubject(MimeUtility.encodeText(strSubject,"iso-2022-jp","B"));
         msg.setText(strBody+"\n");
 
         Transport.send(msg);
     
  } catch {
         case e:AddressException => printf("Exp_A(%s)\n", e.getMessage)
         case e:MessagingException => printf("Exp_B(%s)\n", e.getMessage)
         case e => e.printStackTrace
  }
  }
}

エラー処理とかとても適当ですが、何かの参考に。
