Hi
The following code causes an error. Please help me understand what's wrong.
import javax.mail.*;
import javax.mail.internet.*;
import java.util.*;
public class SendMail
{
public static void main(String [] args)throws MessagingException
{
SendMail sm=new SendMail();
sm.postMail(new String[]{"
[email protected]"},"hi","hello","
[email protected]");
}
public void postMail( String recipients[ ], String subject, String message , String from) throws MessagingException
{
boolean debug = false;
//Set the host smtp
address
Properties props = new Properties();
props.put("mail.smtp.host", "webmail.emailmyname.com");
// 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);
// Optional : You can also set your custom headers in the Email if you Want
msg.addHeader("MyHeaderName", "myHeaderValue");
// Setting the Subject and Content Type
msg.setSubject(subject);
msg.setContent(message, "text/plain");
Transport.send(msg);
}
}
