Probleme javamail

Bonjour,
je souhaite compiler une class d'envoi des email sous eclipse elle est basé sur javamail j'ai installé un srveur smtp et ajouter mail.jar et activation.jar voila le code source:
import java.util.*;
import javax.mail.*;
import javax.mail.internet.*;

public class sendmessage {
public static void main(String[] args) {
if (args.length != 4) {
System.out.println("usage: sendmessage <to> <from> <smtphost>" +"<true|false>");
System.exit(1);
}
boolean debug = false; // change to get more information
String msgText = "A body.\nthe second line.";
String msgText2 = "Another body.\nmore lines";
boolean sendmultipart =
Boolean.valueOf(args[3]).booleanValue();
// set the host
Properties props = new Properties();
props.put("mail.smtp.host", args[2]);
// create some properties and get the default Session
Session session = Session.getDefaultInstance(props, null);
session.setDebug(debug);
try {
// create a message
Message msg = new MimeMessage(session);
// set the from
InternetAddress from = new InternetAddress(args[1]);
msg.setFrom(from);
InternetAddress[] address =
{new InternetAddress(args[0])};
msg.setRecipients(Message.RecipientType.TO, address);
msg.setSubject("JavaMail APIs Test");
if (!sendmultipart) {
// send a plain text message
msg.setContent(msgText, "text/plain");
} else {
// send a multipart message
// create and fill the first message part
MimeBodyPart mbp1 = new MimeBodyPart();
mbp1.setContent(msgText, "text/plain");
// create and fill the second message part
MimeBodyPart mbp2 = new MimeBodyPart();
mbp2.setContent(msgText2, "text/plain");
// create the Multipart and its parts to it
Multipart mp = new MimeMultipart();
mp.addBodyPart(mbp1);
mp.addBodyPart(mbp2);
// add the Multipart to the message
msg.setContent(mp);
}
Transport.send(msg);
} catch (MessagingException mex) {
mex.printStackTrace();
}
}
}
en compilant la class eclipse affiche le message d'erruer suivant :
javax.mail.SendFailedException: Invalid Addresses;
nested exception is:
