Thread: JavaMail and Gmail

Hi!

The program of JavaMail to send email by using gmail SMTP server was working correctly in Windows 7. When I tested the program in Windows XP in a different machine, then the email is not going. Either Messaging or SendMail exception comes. I have used JDK1.6 and NetBeans 5.5 in both the machines.

Kindly let me know whether the problem is because of change of OS (in which case some changes in coding may be needed) or some setting needs to be done in NetBeans, which was taken automatically in Windows 7.

The code is=

/*

*

public class SendMail {
 
String username=null;
String password=null;
 
/** Creates a new instance of SendMail */
public SendMail() {
}
 
public void postMail( String recipients[ ], String subject, String message, String from, String pwd) throws MessagingException
{
boolean debug = false;
 
//Set the host smtp address
Properties props = new Properties();
//props.put("mail.smtp.host", "smtp.live.com");
 
String host="smtp.gmail.com";
props.put("mail.smtps.auth", "true"); 
 
 
// Authenticator a1= new PopupAuthenticator();
 
 
// create some properties and get the default Session
Session session = Session.getDefaultInstance(props, null);
session.setDebug(debug);
 
// create a message
Message msg = new MimeMessage(session);
 
// set the from and to address
//InternetAddress addressFrom = new InternetAddress(from);
//msg.setFrom(addressFrom);
 
InternetAddress[] addressTo = new InternetAddress[recipients.length]; 
for (int i = 0; i < recipients.length; i++)
{
addressTo[i] = new InternetAddress(recipients[i]);
}
msg.setRecipients(Message.RecipientType.TO, addressTo);
 
// Setting the Subject and Content Type
msg.setSubject(subject);
msg.setContent(message, "text/plain");
//msg.setText(message);
//Transport.send(msg); 
 
username = from;
password = pwd; 
 
Transport t = session.getTransport("smtps");
try {
t.connect(host, username, password);
//t.connect(host, username);
t.sendMessage(msg, msg.getAllRecipients());
} 
catch(Exception ex)
{
out.println(ex);
}
finally {
t.close();
}
 
}
 
}

The exception generated is:

javax.mail.MessagingException: can't determine local email address
