Javamail 'NoSuchMethod' error during connect

Question

Code JDC Tech Tip "RETRIEVING MAIL WITH THE JAVAMAIL API" (http://java.sun.com/developer/JDCTechTips/2002/tt0122.html#tip1):
import java.io.*;
import java.util.Properties;
import javax.mail.*;
import javax.mail.internet.*;
public class Fetch {
public static void main (String args[])
throws Exception {
String host = args[0];
// Get system properties
Properties props = System.getProperties();
props.put("mail.pop3.host", host);
// Setup authentication, get session
Authenticator auth = new PopupAuthenticator();
Session session = Session.getDefaultInstance(props, auth);
// Get the store
Store store = session.getStore("pop3");
store.connect();
// Get folder
Folder folder = store.getFolder("INBOX");
folder.open(Folder.READ_ONLY);
// Get directory
Message message[] = folder.getMessages();
for (int i=0, n=message.length; i<n; i++) {
System.out.println(i + ": "
+ message.getFrom()[0]
+ "\t" + message[i].getSubject());
String content =
message[i].getContent().toString();
if (content.length() > 200) {
content = content.substring(0, 200);
System.out.print(content);
// Close connection
folder.close(false);
store.close();
System.exit(0);
The authenticator class is runs through fine, but when it tries to connect I get the following error:
java.lang.NoSuchMethodError: javax.mail.Session.getDebugOut()Ljava/io/PrintStream;
at com.sun.mail.pop3.POP3Store.getPort(POP3Store.java:160)
at com.sun.mail.pop3.POP3Store.protocolConnect(POP3Store.java:102)
at javax.mail.Service.connect(Service.java:246)
at javax.mail.Service.connect(Service.java:131)
at javax.mail.Service.connect(Service.java:87)
at Fetch.main(Fetch.java:21)
The mail jars are in both my <Java home>\hre\lib\ext and <JRE home>\lib\ext directories, and I can see the getDebugOut() method described in the same javax.mail.Session class that was used to build the Fetch class. Using J2SE V1.4.2 and Javamail V1.3.1 / JAFafvaa.Any help you folks can offer with this problem would be greatly appreciated. Thanks in advance!

OK, SUE, I forgot to change the host name to my POP server. Did that and now I'm getting:
javax.mail.AuthenticationFailedException
at javax.mail.Service.connect(Service.java:252)
at javax.mail.Service.connect(Service.java:131)
at javax.mail.Service.connect(Service.java:87)
at Fetch.main(Fetch.java:21)
I've used two ID's that I have under Yahoo, both of which work w/Outlook Express and and the Yahoo web portal. Any ideas what's wrong here?
