Problem fetching the mails

Question

I am writing a simple program to fetch the mails from the mail server using the following code :
public static void main (String args[]) throws Exception {
String username = args[0];
String password = args[1];
Properties props = new Properties();
Session session = Session.getDefaultInstance(props, null);
Store store = session.getStore("pop3");
store.connect("pop.mail.yahoo.com", username, password);
Folder folder = store.getFolder("INBOX");
folder.open(Folder.READ_ONLY);
BufferedReader reader = new BufferedReader (
new InputStreamReader(System.in));
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());
System.out.println("Do you want to read message? [YES to read/QUIT to end]");
String line = reader.readLine();
if ("YES".equals(line)) {
System.out.println(message[i].getContent());
} else if ("QUIT".equals(line)) {
break;
folder.close(false);
store.close();
In this code at the line :
Store store = session.getStore("pop3");
it throws an exception while executing the program : javax.mail.NoSuchProviderException : pop3
i have placed the pop3mail.jar, mail.jar & activation.jar in my classpath still this is the problem.
is there any other provider that is needed ? and if yes from where to get that and where to specify that ?
reply highly appreciable .
thanx

Answer 1

Try changing the store/connection portion of your code from:
Store store = session.getStore("pop3");
store.connect("pop.mail.yahoo.com", username, password);
tp:
Store store = session.getStore("pop.mail.yahoo.com",username,password);
store.connect();
