jbossを設定してメールを送信する

Question

jbossのサーブレットから電子メールを送信したいと思います。私はjboss mail-service.xmlファイルを変更しました。ここに私のサーブレットのコードです。

import java.io.*; 
import java.net.*; 

import java.util.Properties; 
import javax.mail.AuthenticationFailedException; 
import javax.mail.Authenticator; 
import javax.mail.PasswordAuthentication; 
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; 
import javax.servlet.*; 
import javax.servlet.http.*; 

public class Email extends HttpServlet { 

    protected void processRequest(HttpServletRequest request, 
            HttpServletResponse response) 
        throws IOException, ServletException { 

     final String err = "/error.jsp"; 
     final String succ = "/success.jsp"; 

     String from = "*******@gmail.com"; 
     String to = "*******@yahoo.in"; 
     String subject = "from servlet"; 
     String message = "HI"; 
     String login = "***@gmail.com"; 
     String password = "*******"; 

     try { 
      Properties props = new Properties(); 
      props.setProperty("mail.host", "smtp.gmail.com"); 
      props.setProperty("mail.smtp.port", "465"); 
      props.setProperty("mail.smtp.auth", "true"); 
      props.setProperty("mail.smtp.starttls.enable", "true"); 

      Authenticator auth = new SMTPAuthenticator(login, password); 

      Session session = Session.getInstance(props, auth); 

      MimeMessage msg = new MimeMessage(session); 
      msg.setText(message); 
      msg.setSubject(subject); 
      msg.setFrom(new InternetAddress(from)); 
      msg.addRecipient(Message.RecipientType.TO, new InternetAddress(to)); 
      Transport.send(msg); 

     } catch (AuthenticationFailedException ex) { 
      /*request.setAttribute("ErrorMessage", "Authentication failed"); 

      RequestDispatcher dispatcher = request.getRequestDispatcher(err); 
      dispatcher.forward(request, response);*/ 
      System.out.println("Authentication failed"); 

     } catch (AddressException ex) { 
      /*request.setAttribute("ErrorMessage", "Wrong email address"); 

      RequestDispatcher dispatcher = request.getRequestDispatcher(err); 
      dispatcher.forward(request, response);*/ 
      System.out.println("Wrong Email Address"); 

     } catch (MessagingException ex) { 
      /*request.setAttribute("ErrorMessage", ex.getMessage()); 

      RequestDispatcher dispatcher = request.getRequestDispatcher(err); 
      dispatcher.forward(request, response);*/ 
      System.out.println("asdsad"+ex.getMessage()); 
     } 
      /*RequestDispatcher dispatcher = request.getRequestDispatcher(succ); 
      dispatcher.forward(request, response);*/ 
      System.out.println("Success"); 
    } 

    private class SMTPAuthenticator extends Authenticator { 

     private PasswordAuthentication authentication; 

     public SMTPAuthenticator(String login, String password) { 
      authentication = new PasswordAuthentication(login, password); 
     } 

     protected PasswordAuthentication getPasswordAuthentication() { 
      return authentication; 
     } 
    } 

    protected void doGet(HttpServletRequest request, 
         HttpServletResponse response) 
        throws ServletException, IOException { 
     processRequest(request, response); 
    } 

    protected void doPost(HttpServletRequest request, 
          HttpServletResponse response) 
        throws ServletException, IOException { 
     processRequest(request, response); 
    } 
} 

ここは私のmail-service.xmlファイルです。

mbean code="org.jboss.mail.MailService" name="jboss:service=Mail"> 
<attribute name="JNDIName">java:/Mail</attribute>

    <!-- Enable debugging output from the javamail classes --> 
    <property name="mail.debug" value="false" /> 
    </configuration> 
</attribute> 
<depends>jboss:service=Naming</depends> 

しかし、私は次の例外と根本的な原因を取得しています実行しています。

どこが間違っていますか？

Answer 1

mailservice.xmlに変更はありません。サーブレットのdoPostメソッドで他のものをすべて削除して貼り付けます。私はそれがあなたのために働くことを望む。

String host = "smtp.gmail.com"; 
     String from = "user@gmail.com"; 
     String pass = "*******"; 
     Properties props = System.getProperties(); 
     props.put("mail.smtp.starttls.enable", "true"); // added this line 
     props.put("mail.smtp.host", host); 
     props.put("mail.smtp.user", from); 
     props.put("mail.smtp.password", pass); 
     props.put("mail.smtp.port", "587"); 
     props.put("mail.smtp.auth", "true"); 

     String[] to = {"usr@yahoo.in"}; // added this line 

     Session session = Session.getDefaultInstance(props, null); 
     MimeMessage message = new MimeMessage(session); 
     message.setFrom(new InternetAddress(from)); 

     InternetAddress[] toAddress = new InternetAddress[to.length]; 

     // To get the array of addresses 
     for(int i=0; i < to.length; i++) { // changed from a while loop 
      toAddress[i] = new InternetAddress(to[i]); 
     } 
     System.out.println(Message.RecipientType.TO); 

     for(int i=0; i < toAddress.length; i++) { // changed from a while loop 
      message.addRecipient(Message.RecipientType.TO, toAddress[i]); 
     } 
     message.setSubject("sending in a group"); 
     message.setText("Welcome to JavaMail"); 
     Transport transport = session.getTransport("smtp"); 
     transport.connect(host, from, pass); 
     transport.sendMessage(message, message.getAllRecipients()); 
     transport.close();
