から呼び出されます。電子メールはアクティベーションコードで構成されています。は、電子メールを送信するためにクラスを設定する支援が必要、それは私は、ユーザーが最初にログインしたときに自分のアプリケーションから電子メールを送信しようとしていますメインクラス
アップデート：私は、最新のJavaMail APIをダウンロードし、また、最新のJAF（JavaBeansの起動フレームワーク）と、それは未知のシンボルであること輸入のためにコンパイルされません。 javaxパッケージからインポートするにはどうすればいいですか？ここで
は、私がこれまでに得たコードは次のとおりです。ここで
import java.util.ArrayList;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.AddressException;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
public class Email {
static String smtpHost;
static int smtpPort;
static String from;
static String to;
static String subject;
static String content;
public Email(String toEmail, String code){
smtpHost = "localhost";
smtpPort = 25;
from = "[email protected]";
to = toEmail;
subject = "Hello from Nestroia.com";
content = "This is your activation code: " + code;
}
public Email(String toEmail, String name, String password){
smtpHost = "localhost";
smtpPort = 25;
from = "[email protected]";
to = toEmail;
subject = "Hello from Nestroia.com";
content = "This is your Login information.\n"
+ "Name: " + name + "\n"
+ "Password: " + password;
}
public static void send() throws AddressException, MessagingException {
// Create a mail session
java.util.Properties props = new java.util.Properties();
props.put("mail.smtp.host", smtpHost);
props.put("mail.smtp.port", ""+smtpPort);
Session session = Session.getDefaultInstance(props, null);
// Construct the message
Message msg = new MimeMessage(session);
msg.setFrom(new InternetAddress(from));
msg.setRecipient(Message.RecipientType.TO, new InternetAddress(to));
msg.setSubject(subject);
msg.setText(content);
// Send the message
Transport.send(msg);
