Ask help on javamail

Question

When I run the following code, "javax.mail.NoSuchProviderException: No provider for Address type: rfc822" is throwed when it comes to the line "Transport.send(message);".
Does anyone can tell me the reason?
Thanks a lot!
import java.util.*;
import javax.mail.*;
import javax.mail.internet.*;
public class HshSendMessage
public static void main(String[] a)
try
/* if(args.length < 5)
System.out.println("java com.psol.xslist.SendMessage" +
" [email protected] [email protected] mailhost.domain.com" +
" subject \"mail content\"");
return;
String args[]={"[email protected]","[email protected]","mail.hotmail.com","subject","You have a task!"};
          Properties props = System.getProperties();
          props.put("mail.smtp.host",args[2]);
     Session session = Session.getDefaultInstance(props, null);
//     if (debug)
          session.setDebug(true);
Message message = new MimeMessage(session);
InternetAddress from = new InternetAddress(args[1]);
InternetAddress to[] = InternetAddress.parse(args[2]);
message.setFrom(from);
message.setRecipients(Message.RecipientType.TO,to);
message.setSubject(args[3]);
message.setSentDate(new Date());
message.setText(args[4]);
Transport.send(message);
catch(MessagingException e)
System.err.println(e.getMessage());

Have you downloaded and installed Java Activation Framework from Sun?
You need the activation.jar in your classpath to have Java mail works, I think I have
this problem before and that solved it.
