Help me to run my first JavaMail app

[Hussein Baghdadi]

Hey all.
this is my first day in JavaMail.
I want to send an email from [email protected] to [email protected] address.
I have the following class :

  
import java.util.Properties;
import javax.mail.*;
import javax.mail.internet.*;
 
public class SendMail {
 public static void main(String[] args) {
 // Get properties object
 Properties props = System.getProperties();
 // Define SMTP host property
 props.put("mail.smtp.host","mail.yahoo.com");
 try {
  // Get a session
  Session session = Session.getDefaultInstance(props,null);
  // Create a new message object
  MimeMessage message = new MimeMessage(session);
  // Populate message object
  message.setText("Hello from first JavaMail message");
  message.setSubject("Hi!");
  message.setFrom(new InternetAddress("[e-mail]"));
  message.addRecipient(Message.RecipientType.TO,new InternetAddress("[e-mail]"));
  // Send the message
  Transport.send(message);
 }catch (MessagingException me) {
   System.err.println(me.getMessage());
 }
   System.out.println("Message Sent");
 }
} 

connecting to the internet and running the application, I got :

 
Sending failed;
  nested exception is:
        class javax.mail.MessagingException: Could not connect to
l.yahoo.com, port: 25;
  nested exception is:
        java.net.SocketException: Network is unreachable: connect

note : I am behind a proxy, so any special configuration here ?
thanks for help.

try this and see if there is any difference:

 
systemSettings.put("proxySet", "true");
systemSettings.put("proxyHost", PROXY_SERVER_IPADDRESS);
systemSettings.put("proxyPort", PROXY_SERVER_PORT);
 

Obviously substiture PROXY_SERVER_IPADDRESS and PROXY_SERVER_PORT for your proxy ip and port.

The same result.

Mine problem is similar to yours. My code is a little different but does the same thing. The servlet worked successfully. But the message was not sent.

......
......
 
       // get the message parameters from the HTML page
       String from = request.getParameter( "sender" );
       String to = request.getParameter( "receiver" );
       String subject = request.getParameter( "messageTopic" );
       String text = request.getParameter( "messageBody" );
/*
       if (from == null) from = mailOption.defaultEmailFrom;
 */
 
       PrintWriter out = response.getWriter();
       response.setContentType( "text/html" );
 
       try
       {
           // set the SMTP host property value
           Properties props = System.getProperties();
           props.put( "mail.smtp.host", "XP-JENC-C.milky-way.smtp.NameOfMyCompany.org" );
 
           // create a JavaMail session
           Session session = Session.getInstance( props, null );
 
           // create a new MIME message
           MimeMessage message = new MimeMessage( session );
 
           // set the from address
           Address fromAddress = new InternetAddress( from );
           message.setFrom( fromAddress );
 
           // set the to address
           if ( to != null )
           {
               Address[] toAddress = InternetAddress.parse( to );
               message.setRecipients( Message.RecipientType.TO, toAddress );
           }
           else
               throw new MessagingException( "No \"To\" address specified" );
 
           // set the subject
           message.setSubject( subject );
 
           // set the message body
           message.setText( text );
 
           // send the message
           Transport.send( message );
 
           out.println( "Message sent successfully."  );
      }
      catch (AddressException e)
      {
         out.println( "Invalid e-mail address.<br>" + e.getMessage() );
      }
      catch (SendFailedException e)
      {
         out.println( "Send failed.<br>" + e.getMessage() );
      }
      catch (MessagingException e)
      {
         out.println( "Unexpected error.<br>" + e.getMessage() );
      }

Well you need to be sure that your proxy supports SMTP, which would be unusual.
